Star houseplants and garden plants in 2026: the guide to plant trends

Daniel Platteau Articles indoor plant

In 2026, plants are no longer mere decoration: they follow aesthetic trends, respond to drier summers and sometimes become genuine collector's items. Whether you want to turn your home into an urban jungle or plant a garden that copes better with heat, some plants stand out. 🌿

This guide reviews the most sought-after houseplants with graphic foliage (Alocasia, Philodendron 'Pink Princess', Strelitzia, variegated Monstera), then a few garden stars that combine looks and resilience ('Violet de Provence' artichoke, dark foliage, pollinator plants). For each: what makes it desirable, its drawbacks, and how to grow it.

Part 1: star houseplants, XXL and graphic foliage

Houseplants with spectacular foliage have been among the most searched-for purchases of recent years, with cultivars such as Alocasia 'Pink Dragon' or Philodendron 'Pink Princess'. Their success comes from their exotic, graphic and lush look.

1. Alocasias: the queens of graphic foliage

Alocasia 'Pink Dragon': pink stems and silvery leaves

Description: Alocasia 'Pink Dragon' is a cultivar that stands out for:

• pink petioles (leaf stalks);
• arrow-shaped leaves, silvery green on top with strongly marked dark veins, and a purplish underside;
• an adult size of 60 cm to 1 m indoors.

Origin: Alocasia are native to the tropical forests of Southeast Asia and Oceania. 'Pink Dragon' is a horticultural selection, widely spread in recent years by specialist growers and social media.

Advantages: ✅ Guaranteed "wow" effect: its graphic foliage makes it a very sought-after plant. ✅ Fairly fast growth: in good conditions it regularly produces new leaves during the growing season.

Drawbacks and precautions: ⚠️ Toxic: like all Alocasia, it contains calcium oxalate crystals that irritate the mouths of cats, dogs… and children. ⚠️ Sensitive to overwatering: watering too often rots the roots. ⚠️ Needs bright indirect light: without enough light, it becomes leggy and slows down. ⚠️ Possible winter dormancy: it may drop leaves in winter; this is not necessarily a sign of disease.

Growing tips:

• Light: bright indirect light (east- or west-facing window). Avoid direct sun, which scorches the leaves.
• Watering: let the top 2 to 3 centimetres of mix dry out between waterings; water less in winter.
• Humidity: ideally 60 to 70% (humidifier or tray of damp clay pebbles).
• Temperature: 18 to 25 °C, away from cold draughts.
• Feeding: liquid houseplant fertiliser at half strength every 2 to 3 weeks in spring and summer.

Where to buy it? From specialist tropical-plant growers and nurseries, garden centres, or online marketplaces (check reviews and ask for a recent photo of the plant). Expect to pay a few tens of euros depending on size.

Alocasia 'Black Velvet': dark velvet

Description: Alocasia reginula 'Black Velvet' is a compact plant (30 to 50 cm) with almost black, matt foliage criss-crossed by strongly contrasting silvery veins. Its leaves are velvety to the touch, hence its name.

Origin: Alocasia reginula is native to Borneo. Its mysterious look has made it a collectors' favourite.

Advantages: ✅ Dramatic effect: perfect for modern interiors. ✅ Compact size: ideal for small spaces.

Drawbacks: ⚠️ Toxicity: like all Alocasia, keep it out of reach of pets and children. ⚠️ Prone to mites: watch out for red spider mites, especially in dry air. ⚠️ Slow growth: it produces few leaves a year.

Specific tips:

• Light: medium to bright indirect light.
• Watering: let the surface dry slightly; it hates excess water.
• Growing medium: a very airy mix (tropical-plant compost, perlite, bark).

2. Philodendron 'Pink Princess': the pink variegated one

Description: Philodendron erubescens 'Pink Princess' ("PPP" to its friends) is a cultivar with dark green foliage variegated with pink, and elongated heart-shaped leaves.

Origin and popularity: The species Philodendron erubescens is native to the tropical forests of Colombia. The pink variegation of 'Pink Princess' is unstable: it varies from leaf to leaf and can disappear. The cultivar went through a spectacular craze around 2018–2021, with prices reaching dizzy heights, before falling sharply thanks to mass production.

Advantages: ✅ Unique look: few plants offer such marked pink variegation. ✅ Easier than Alocasias: copes better with average humidity. ✅ Versatile: can climb a moss pole.

Drawbacks: ⚠️ Toxic: contains calcium oxalate crystals (take care with pets and children). ⚠️ Reversion to green: some plants lose their variegation. Choose a plant whose recent leaves are well variegated, and be wary of plants sold very cheaply or of all-pink leaves, which are more fragile. ⚠️ Very pink leaves are fragile: the pink areas have no chlorophyll and brown easily.

Growing tips:

• Light: bright indirect light; too little light encourages reversion.
• Watering: let the surface of the mix dry between waterings.
• Humidity: around 50%; raise it a little in winter if the air is dry.
• Feeding: diluted houseplant fertiliser in spring and summer.

Tip: If a stem is producing only green leaves, cut it back just above a leaf that is still well variegated: the new shoot is more likely to be variegated too.

3. Strelitzia (bird of paradise): living architecture

Description: Strelitzia ("bird of paradise") is a monumental plant from South Africa. Its large, leathery leaves arranged in a fan give it an architectural look. Two species dominate the market:

• Strelitzia nicolai: the big one, with leaves resembling a banana's; 2 m or more indoors, much more in the ground in hot climates.
• Strelitzia reginae: more compact (1 to 1.5 m), famous for its orange and blue flowers.

Origin and symbolism: The genus was named in honour of Queen Charlotte of Mecklenburg-Strelitz, wife of King George III. It is an emblematic plant of "urban jungle" interiors.

Advantages: ✅ Statement effect: a single plant can transform a living room. ✅ Longevity: it can live for many years in a pot.

Drawbacks: ⚠️ Imposing size: it needs room (conservatory, high-ceilinged room). ⚠️ Needs a lot of light: without enough light, it does not flower and becomes leggy. ⚠️ Not entirely harmless: the ASPCA lists Strelitzia reginae as toxic to dogs and cats (digestive upset), especially the fruit and seeds.

Growing tips:

• Light: as much as possible, including a few hours of direct sun (south- or west-facing window); put it outside in summer, acclimatising it gradually.
• Watering: let the surface dry between waterings; water much less in winter.
• Temperature: 15 to 25 °C; frost-free in winter. In our climate it is an indoor or conservatory plant.
• Feeding: houseplant fertiliser in spring and summer.

Flowering (S. reginae): Indoors, flowers only come on a mature plant, often after several years. To encourage them: maximum light (outdoors in summer), a slightly cramped pot, flowering-plant fertiliser in season and a cooler (around 12 to 15 °C), drier winter.

4. Variegated Monstera: queen of variegated leaves

Description: Monstera deliciosa 'Variegata' (often sold as 'Albo Variegata' or 'Thai Constellation') has leaves variegated with white or cream, perforated and split like those of the species. In a pot, its leaves commonly reach 40 to 60 cm.

Origin and popularity: Monstera deliciosa is native to Mexico and Central America. The variegated forms ('Albo', unstable, from a mutation; 'Thai Constellation', more stable, from tissue culture) have become collector's plants.

Advantages: ✅ Graphic effect: unique variegated, perforated leaves. ✅ Easier to grow than Alocasias.

Drawbacks: ⚠️ Toxic: contains calcium oxalate crystals; chewing causes mouth irritation and heavy drooling. ⚠️ High price: often several tens to several hundred euros, depending on size and the quality of the variegation. ⚠️ Slower growth and reversion: the white areas do not photosynthesise; 'Albo' can also revert to green or, conversely, produce all-white leaves that do not survive.

Growing tips:

• Light: bright indirect light; too little light encourages reversion.
• Watering: let the top 3 to 4 centimetres dry out between waterings.
• Humidity: 50 to 60%.
• Support: a moss or coir pole to guide its growth.
• Feeding: balanced fertiliser at half strength every 3 to 4 weeks in spring and summer.

What about the "air-purifying plant" claim?

You read everywhere that these plants "purify the air". The often-quoted 1989 NASA study was carried out in small sealed chambers; in a real, ventilated home, more recent work shows that the effect of a few plants on air quality is negligible. Buy them for their beauty, and air your home.

Part 2: garden stars in 2026, good-looking vegetable plots and resilience

In the garden, trends are driven by:

• climate change (drier summers, milder winters);
• the wish to combine the useful and the beautiful (a vegetable garden that is edible and attractive);
• biodiversity (pollinator plants that need little care).

1. The 'Violet de Provence' artichoke: the ornamental vegetable

Description: The artichoke (Cynara cardunculus, Scolymus group) 'Violet de Provence' is a variety with purple heads, both edible and ornamental. Its large, silvery, deeply cut leaves bring a graphic touch to the garden, and unharvested heads open into spectacular blue-violet flowers.

Origin: The artichoke comes from the Mediterranean basin and has been grown for centuries. 'Violet de Provence' is a traditional variety from the south of France, harvested young.

Advantages: ✅ Dual use: edible (heart and base of the bracts) and ornamental. ✅ Copes well with heat once established. ✅ Attracts pollinators: the open flowers are heavily visited by bees and bumblebees.

Drawbacks: ⚠️ A bulky perennial: it stays in place for 3 to 5 years and can reach 1.5 m high and 1 m wide. ⚠️ Sensitive to cold and wet: 'Violet de Provence' is one of the least hardy; protect the crown with a thick mulch from the first frosts, especially in heavy soil. ⚠️ Modest harvest in the first year.

Growing tips:

• Position: full sun.
• Soil: rich, deep and well drained; add compost at planting.
• Watering: regular during the first year and while the heads are forming.
• Feeding: compost or well-rotted manure in spring.
• Winter protection: earth up and mulch the crown in autumn.

Companions in the vegetable garden:

• with Mediterranean herbs (thyme, rosemary, sage);
• with flowers (nasturtiums, calendula) to attract beneficial insects.

Where to find it? As plants from nurseries and garden centres in spring, or as seed from seed companies (for example Kokopelli). Plants grown from offsets reproduce the variety better than seedlings.

2. Dark foliage and flowers: striking contrast

Gardens in purple, chocolate or almost black tones are fashionable for creating striking contrasts.

Lilium 'Night Rider': the almost-black lily

Description: Lilium 'Night Rider' (sometimes written 'Nightrider') is a hybrid lily with very dark purple, almost black flowers with a lighter centre. Its stems reach about 1 m.

Advantages: ✅ Dramatic effect: perfect for dark-toned borders. ✅ Easy: like most hybrid lilies, it flowers well from the first year.

Drawbacks: ⚠️ Highly toxic to cats: every part of the lily, including the pollen and the vase water, can cause acute kidney failure in cats. Avoid it completely if you have a cat. ⚠️ Lily beetle: this small red beetle and its larvae devour the foliage; check plants from spring onwards. ⚠️ Slugs: they attack young shoots.

Growing tips:

• Position: sun, with the base in shade (low perennials around it work well).
• Soil: rich and well drained; bulbs rot in waterlogged soil.
• Planting: bulbs about 15 cm deep, in autumn or early spring.
• Watering: regular in spring and summer, without excess.

Tip: Pair it with pale foliage (such as heuchera 'Lime Rickey') for maximum contrast.

Dark heucheras: stars of the border

Description: Heuchera (coral bells) are perennials with colourful foliage, from acid green to almost-black purple. Dark varieties such as:

• Heuchera 'Obsidian' (black-purple);
• Heuchera 'Plum Pudding' (plum);
• Heuchera 'Black Beauty' (dark purple, ruffled leaves)

are very popular for edging, borders and containers.

Origin: Native to North America, heucheras are grown for their evergreen foliage and ease of growing.

Advantages: ✅ Evergreen foliage: decorative almost all year. ✅ Undemanding: they grow in a wide range of soils. ✅ Flowers visited by pollinators: their little bells attract bees.

Drawbacks: ⚠️ Scorch in strong sun: dark varieties tolerate sun better than pale ones, but not in dry soil. ⚠️ Vine weevil: the larvae of this weevil devour the roots, especially in pots. ⚠️ Crown lifts out of the soil: replant deeper every 3 to 4 years.

Growing tips:

• Position: preferably partial shade; morning sun is fine.
• Soil: rich, moist and well drained.
• Watering: keep the soil moist in summer.
• Division: every 3 to 4 years to rejuvenate the clump.

Companions:

• with hostas and ferns for a shady garden;
• in containers with pale foliage (such as Carex 'Evergold').

3. Easy pollinator plants: for a useful garden

With drier summers, gardeners are looking for easy pollinator plants that feed bees and butterflies without needing constant care.

Thunbergia alata (black-eyed Susan vine): the summer climber

Description: Thunbergia alata ("black-eyed Susan vine") is a climber from East Africa, perennial in the tropics but grown in our climate as an annual. Its yellow, orange or white flowers with a black centre follow one another all summer, and its leaves are heart-shaped.

Why people love it:

• fast growth: 1.5 to 2 m in a season;
• continuous flowering from summer to the frosts;
• easy: ideal for beginners, in a pot on a sunny balcony or at the foot of a trellis.

Drawbacks: ⚠️ Frost-tender: it dies at the first frosts (sow it again each year or overwinter it under glass). ⚠️ Not really drought-tolerant: in pots it needs regular summer watering. ⚠️ Red spider mite and whitefly possible in hot, dry weather.

Growing tips:

• Position: full sun or light sun.
• Soil: rich and well drained, kept moist.
• Support: trellis, wire mesh, obelisk.
• Sowing: in warmth in March–April, planting out after the last frosts (mid-May in our climate).

Echinacea: the star of flowering meadows

Description: Echinacea (coneflowers) are North American perennials with pink, purple, white or orange flowers and a characteristic cone-shaped centre. Among the most widely grown:

• Echinacea purpurea (purple-pink), the species itself;
• Echinacea purpurea 'White Swan' (white);
• Echinacea 'Hot Papaya' (orange-red, double).

Why people love them:

• good drought tolerance once established;
• heavily visited by pollinators, and their seeds feed birds in winter if you leave the heads in place;
• long flowering, from about July to September.

Drawbacks: ⚠️ Dislike winter wet: in heavy, waterlogged soil the crown rots. ⚠️ Hybrids sometimes short-lived: very colourful or double cultivars often live less long than the species. ⚠️ Slugs on young shoots in spring.

Growing tips:

• Position: full sun.
• Soil: well drained, even fairly poor.
• Watering: moderate; regular in the first year only.
• Feeding: little needed; a little compost in spring is enough.

Companions:

• with grasses (Stipa, Miscanthus) for a meadow effect;
• with salvias, catmints and lavenders.

Part 3: general tips for success with these star plants

1. Watering: the key point

Golden rule: better slightly too dry than too wet.

• Tropical houseplants (Alocasia, Philodendron, Monstera):
  • let the top few centimetres of mix dry between waterings;
  • use a free-draining mix (compost, perlite, pine bark);
  • never leave water standing in the saucer.
• Garden plants (artichoke, echinacea, heuchera):
  • water regularly in the first year to encourage rooting;
  • then water according to the plant and the weather; a mulch reduces the need.

Tip: a simple wooden stick pushed into the mix shows whether it is still moist deeper down.

2. Light: the most underestimated factor

• Houseplants with graphic foliage: bright indirect light, without scorching sun; in winter, move them closer to windows.
• Strelitzia: as much light as possible, direct sun included.
• Garden plants: full sun for artichoke, echinacea, Thunbergia and lilies; partial shade for heucheras.

3. Humidity: crucial for tropical plants

Alocasias and, to a lesser extent, Philodendrons and Monsteras like high humidity.

• Humidifier: the most effective solution in winter.
• Tray of damp clay pebbles under the pot (without the bottom sitting in water).
• Grouping plants: together they create a more humid microclimate.
• Misting only raises humidity for a few minutes: it is an extra, not a solution.

4. Growing medium and repotting

• Tropical houseplants: houseplant compost, perlite and pine bark; repot about every 2 years, or when roots come out of the pot; always a pot with holes.
• Garden plants: garden soil improved with compost.

5. Toxicity and pets

Warning: several of these star plants are toxic to cats and dogs (and irritant for children).

⚠️ Beware of a common mistake: daylilies (Hemerocallis) are just as dangerous to cats as lilies. They are not an alternative.

Tips:

• place toxic plants out of reach (high shelf, hanging basket);
• if a pet eats some, contact a vet straight away; for a child, call a poison centre (in Belgium: 070 245 245; elsewhere, your local poison control centre);
• if you have a cat, give up lilies, including in bouquets.

Where to buy your star plants?

To avoid disappointment (sick plants, unstable variegation, excessive prices), a few pointers:

For houseplants

1. Garden centres and florists: immediately available, and you can see the plant before buying.
2. Specialist tropical-plant growers and shops, in store or online: a wider choice of rare cultivars.
3. Online marketplaces and swaps between individuals: bargains are possible, but check reviews, ask for recent photos and be wary of "too good to be true" variegation at rock-bottom prices.

For garden plants

1. Local nurseries: personalised advice and plants suited to your region.
2. Seed companies: for example Kokopelli or La Bonne Graine for seeds.
3. Garden centres and online shops: a wide choice; prefer well-rooted potted plants.

Precautions and pests

Toxic plants: good habits

• Wear gloves when pruning or repotting Alocasia, Philodendron and Monstera (irritant sap).
• Keep them out of reach of young children, who may be tempted to taste the leaves.
• Wash your hands after handling them.

Pests: prevention and treatment

Preventive tips:

• inspect your plants regularly, especially under the leaves;
• isolate new houseplants for two weeks;
• dust the leaves with a damp cloth.

Conclusion: which star plants should you choose in 2026?

Whether you go for:

• an Alocasia 'Pink Dragon' for a graphic interior,
• a Philodendron 'Pink Princess' for a touch of pink,
• a Strelitzia for an architectural effect,
• a 'Violet de Provence' artichoke for a beautiful, edible vegetable plot,
• echinaceas for a pollinator-friendly garden,

the secret stays the same: choose the plant according to the space, the light and the time you have — and your pets.
