The difference between Tillandsia cyanea and Wallisia cyanea is purely taxonomic. There is no distinction in growth, appearance, or care requirements.

• Tillandsia cyanea – the former scientific name, still widely used in plant shops and literature

• Wallisia cyanea – the currently accepted botanical name since the 2016 taxonomic revision

For growers, collectors, and interior plant styling, both names refer to the same bromeliad species.

Why was Tillandsia cyanea reclassified?

DNA analysis and modern taxonomy

Advances in molecular genetics revealed that Tillandsia cyanea differs significantly from core Tillandsia species. DNA sequencing showed clear genetic separation, particularly in flower structure and growth patterns.

Revival of the genus Wallisia

The genus Wallisia was originally described in 1870 but was later merged into Tillandsia. Based on new scientific evidence, botanists reinstated Wallisia in 2016, assigning cyanea to its correct genus.

Today, Wallisia cyanea is the botanically correct name.

Key characteristics of Wallisia cyanea (Pink Quill plant)

• Plant family: Bromeliaceae

• Inflorescence: Flat, paddle-shaped, bright pink bracts lasting several months

• Flowers: Small violet-blue flowers emerging sequentially from the bracts

• Growth habit: Epiphytic by nature, yet highly adaptable to pot culture

• Decorative value: Long-lasting color and compact form make it ideal for interiors

Wallisia cyanea care guide (indoor cultivation)

Light requirements

• Bright, indirect light to light shade

• Avoid strong direct sunlight

Watering & humidity

• Mist regularly with low-lime or rainwater

• When potted, water moderately and allow excess water to drain

• Prefers higher humidity but adapts well to normal indoor conditions

Substrate & mounting options

• Airy bromeliad or orchid substrate recommended

• Can be mounted on bark or wood

• One of the few "air plants" that grows reliably in pots

Temperature

• Warm to intermediate temperatures

• Not frost tolerant; indoor plant only

Why Wallisia cyanea is ideal for beginners and collectors

Unlike many Tillandsia species, Wallisia cyanea combines exotic appearance with easy care. After flowering, it produces offsets (pups), allowing long-term cultivation and propagation. Its adaptability makes it suitable for beginners, while its botanical background appeals to collectors.

Complete seed propagation guide by TOMs FLOWer CLUB

General background: What is Brachychiton populneus?

Brachychiton populneus, commonly known as the Kurrajong or Bottle Tree, is an evergreen to semi-evergreen tree native to Australia. It is prized for its sculptural, thickened trunk, leathery green leaves, and excellent drought tolerance. In cultivation, Brachychiton populneus is suitable both as a garden tree in mild climates and as a container-grown plant when young.

The species grows slowly to moderately and develops a strong root system early on. This makes seed propagation especially rewarding for patient growers who value robust, long-lived plants grown naturally.

Why propagate Brachychiton populneus from seed?

Seed propagation is the most reliable and natural method to grow healthy Brachychiton populneus. Seed-grown plants:

• develop stronger root systems

• show higher long-term resilience

• adapt better to local growing conditions

While leaf shape and growth vigor may vary slightly, the essential characteristics of the species remain stable.

Understanding Brachychiton seeds

After flowering, Brachychiton populneus produces woody, boat-shaped seed pods. Once mature, these pods split open and release numerous dark seeds covered in fine, irritating hairs.

Good to know: Always wear gloves when handling seeds or pods. The hairs can irritate skin and respiratory passages.

Cleaned seeds store well in a dry, cool place and remain viable for several years.

Best time to sow Brachychiton seeds

The optimal sowing period is spring to early summer.

Ideal germination conditions:

• Soil temperature: 20–25 °C

• Bright location with indirect light

• Frost-free environment

Indoor sowing or a greenhouse setup significantly improves germination success.

Step-by-step guide: How to propagate Brachychiton populneus from seeds

1. Seed preparation

Soak seeds in lukewarm water for 12–24 hours to soften the seed coat and promote even germination.

2. Substrate selection

Use a very well-drained, airy substrate.

Recommended mix (TOMs FLOWer CLUB):

• 50% mineral components (pumice, perlite, sand, or fine gravel)

• 50% high-quality organic soil or coco fiber

The substrate should retain slight moisture but never stay wet.

3. Sowing the seeds

• Place seeds horizontally on the substrate

• Cover lightly with 5–10 mm of soil

• Water gently to settle the mix

4. Germination phase

• Keep evenly moist, never soggy

• Maintain warmth and good airflow

Germination usually occurs within 2–4 weeks, though some seeds may take longer.

Seedling care after germination

Once seedlings appear:

• Move to a very bright location, avoiding strong direct sun initially

• Allow the substrate to dry slightly between watering

• Do not fertilize for the first 6–8 weeks

Because seedlings form a taproot early, deep pots are preferable.

Potting on and further cultivation

When seedlings reach 10–15 cm in height:

• Pot individually into deeper containers

• Use the same well-drained substrate

• Handle roots carefully to avoid taproot damage

Repotting is usually only required every 1–2 years.

Tips & hints for successful cultivation

• Less water is better than too much

• Drainage is essential at all stages

• Gradually acclimate young plants to sun

• Avoid cold, wet conditions, especially in winter

Good to know about Brachychiton populneus

• Juvenile and adult leaves can look very different

• Trunk thickening develops slowly and naturally

• Seed-grown plants are typically stronger than cuttings

• Ideal for growers who enjoy long-term plant development

How to Grow Coleus (Plectranthus scutellarioides) Successfully in European Climates

Coleus (Plectranthus scutellarioides) is one of the most colourful foliage plants available to gardeners and plant lovers. Known for its vibrant leaf patterns in shades of green, burgundy, pink, yellow, and near-black, coleus is easy to grow when its basic needs are understood.

In Europe, coleus is typically grown as a seasonal outdoor plant or as a perennial indoor plant, as it is not frost-hardy. This guide explains how to care for coleus under European climate conditions, whether on a balcony, terrace, garden bed, or indoors.

---

Is Coleus Hardy in Europe?

Coleus is not winter-hardy in most European regions. Temperatures below 10 °C can damage the plant, and frost will kill it.
For this reason:

• Outdoors, coleus is grown from late spring to early autumn

• Indoors, it can be overwintered as a houseplant

• Many gardeners propagate coleus from cuttings each year

---

Light Requirements for Coleus

Proper light is essential for strong growth and intense leaf colour.

• Best light: bright, indirect light

• Outdoors: partial shade or morning sun

• Indoors: close to a bright window, without strong midday sun

Too much direct sun may scorch leaves, while insufficient light can cause faded colours and leggy growth.

---

Ideal Temperature for Coleus

• Optimal growth temperature: 18–28 °C

• Minimum temperature: 10–12 °C

• Protect from cold drafts and sudden temperature drops

In Central Europe, coleus should only be planted outdoors after the last frost in spring.

---

How Often to Water Coleus

Coleus prefers evenly moist soil.

• Water regularly during the growing season

• Allow the top layer of soil to dry slightly between waterings

• Avoid waterlogging, especially in containers

Coleus may wilt quickly when dry but usually recovers after watering.

---

Best Soil for Coleus Plants

For healthy root growth, use:

• A loose, well-draining, organic substrate

• Soil enriched with compost or coconut fibre

• Added perlite or sand for drainage

Good drainage is essential to prevent root rot.

---

Fertilising Coleus for Strong Colour

Coleus is a moderate feeder.

• Apply a balanced liquid fertiliser every 10–14 days

• Fertilise only during active growth (spring to summer)

• Avoid excessive nitrogen, which causes soft growth and weaker colour

---

Pruning and Pinching Coleus

Regular pruning keeps coleus compact and colourful.

• Pinch shoot tips to encourage bushy growth

• Remove flower spikes early

• Cut back leggy plants if necessary

Pruning improves both shape and leaf colour intensity.

---

Growing Coleus Outdoors in Europe

Coleus is ideal for:

• Balconies and terraces

• Containers and mixed planters

• Shaded garden beds

Protect plants from strong wind, heavy rain, and intense midday sun.

---

Overwintering Coleus in Europe

Before temperatures drop below 10 °C, bring coleus indoors.

• Place in a bright room at 15–18 °C

• Water sparingly

• Do not fertilise during winter

Alternative: Overwintering via Cuttings

Taking cuttings in late summer is the most reliable method to keep your favourite varieties.

---

How to Propagate Coleus

Coleus is very easy to propagate.

• Take stem cuttings (8–10 cm)

• Root in water or moist soil

• New plants establish quickly

Propagation ensures identical plants and strong growth.

---

Common Coleus Problems

• Pale leaves: insufficient light or over-fertilisation

• Wilting: underwatering or heat stress

• Leggy growth: lack of pruning or low light

---

Conclusion

Coleus is a versatile and low-maintenance foliage plant for European gardeners. With proper light, regular pinching, and frost protection, it offers outstanding colour from spring to autumn.
