Verbascum chaixii 'Album'

flower

Verbascum chaixii 'Album' is a striking biennial or short-lived perennial flowering plant characterized by tall spikes of pure white flowers with distinctive red or purple centers. This garden favorite produces a basal rosette of fuzzy gray-green leaves in its first year, then sends up impressive flower spikes in the second season that can reach 3-4 feet tall. The plant is valued for its dramatic vertical accent, long flowering period, and ability to thrive in poor, well-draining soils.

Growth Stages

Seed Germination

2-3 weeks

Tiny seedlings emerge with cotyledons; requires light for germination

Sow seeds on soil surface indoors in winter or outdoors in fall. Keep moist but not waterlogged. Provide bright light. Germination occurs in 10-20 days at 65-75°F.

First Year Rosette

6-8 months

Plant develops a low basal rosette of soft, fuzzy gray-green leaves; no flowering

Thin seedlings to 18 inches apart. Keep weed-free. Water occasionally but allow soil to dry between waterings. No staking needed. Cold stratification over winter strengthens plants.

Bolt & Flower Stalk Emergence

4-6 weeks

Strong central stem rapidly extends upward, reaching 3-4 feet; flowering buds form along the spike

Stake if in windy location or heavy soil. Tall plants may flop; provide support with stakes or cages. Begin staking early before height makes it difficult.

Flowering

6-10 weeks

Pure white flowers with red/purple stamens open sequentially from bottom to top along the spike; robust display

Deadhead spent flowers to extend blooming period (though self-seeds readily if left unpruned). Water during dry spells to support heavy flowering. A truly stunning stage lasting 6-10 weeks.

Seed Maturation & Decline

4-8 weeks

Upper flowers fade; seed pods develop along spike; foliage yellows and dies back after prolific seeding

Allow some flowers to remain for seed production if self-seeding is desired; deadhead others to prevent excessive volunteer seedlings. Plant is typically biennial and will decline after seed set.

Companion Planting

Plan your garden →

Plant with:

Catmint (Nepeta) Salvias Lavender Santolina Achillea Dianthus Gaura Echinacea Ornamental grasses Agapanthus

Avoid planting near:

Moisture-loving plants (Hostas, Astilbe) Plants requiring frequent watering (ferns, shade perennials)

Common Pests

Handpick caterpillars; rarely requires chemical control. Remove infested leaves if populations are heavy.
Increase humidity through foliar misting; spray with insecticidal soap or neem oil if severe. Usually not problematic in well-drained conditions.
Ensure good air circulation. Apply sulfur powder or fungicide if needed. Avoid overhead watering. Usually resistant in full sun with good drainage.

Uses

🍳

Herbal Tea

Culinary

Harvest Tips

Verbascum chaixii 'Album' is primarily an ornamental flower, not harvested for food. Cut stems for fresh arrangements at any point during flowering; flowers last 7-10 days in a vase. Allow some seed heads to remain on the plant for self-seeding and ornamental dried interest. Deadhead spent flowers at the base of the spike to redirect energy and extend blooming if continuous flowering is desired (though this prevents natural reseeding).

Fun Facts

🌱 Verbascum flowers open sequentially from the bottom of the spike upward, with only a few flowers open at any given time, providing extended blooming over many weeks.
🌱 The fuzzy, felted leaves contain tiny hairs that historically were used as tinder for starting fires and as lamp wicks—hence an old common name 'Candlewick Plant.'
🌱 Verbascum chaixii is notably less aggressive at self-seeding than some other Verbascum species, making 'Album' a more controlled and elegant garden choice while still offering enough seedlings for continuity.
