Our "Bloom or Bust" Promise

Calla lilies aren’t true lilies. Their “flower” is a spathe (a coloured bract) wrapped around a spadix packed with tiny flowers—why they last so well in vases.

Zantedeschia 'Crystal Blush' brings creamy white blooms that slowly pick up a rosy blush on tall stems above neat, arrow‑shaped leaves. The flowers are actually a smooth ‘spathe’ wrapped around a central spadix, giving that iconic trumpet shape that suits both classic and contemporary gardens.

These summer-flowering rhizomes are outstanding in patio pots, where you can keep the compost evenly moist and enjoy the flowers up close. They also work in sheltered borders, especially in richer soils, and the clean, architectural blooms pair beautifully with grasses and airy annuals.

Plant in spring once the ground has warmed and the risk of frost has passed. Set rhizomes 5–10 cm deep, with the growing points facing up, and space them so the clumps can expand. You’ll usually see shoots appear within a few weeks, followed by flower stems through mid to late summer.

Calla lilies love moisture while they’re growing, so water regularly and feed in containers for the best display. Mulching the soil surface helps reduce drying out in warm weather. If you’re cutting stems, pick as the spathe unfurls and place straight into fresh water for long-lasting arrangements.

These are tender plants in the UK, so protect them from frost. After flowering, let the foliage die back naturally so the rhizome can recharge. In autumn, lift and store the rhizomes somewhere cool, dry and frost‑free, or move pots under cover, ready for replanting next spring.

Where to Plant:

Plant in a sheltered spot in full sun or light partial shade. Rich, humus‑heavy soil that stays evenly moist (but drains well) helps keep stems sturdy—containers work brilliantly.

How to Plant:

Plant rhizomes in spring once frost risk has passed, 5–10 cm deep with the growing points facing up. Space about 25–30 cm apart, or pot up under cover for an earlier start.

Aftercare:

Water regularly through growth and flowering and feed every couple of weeks in pots. After bloom, let foliage die back naturally. In cold areas, lift and store rhizomes dry and frost‑free.
