Hymenocallis × festalis 'Zwanenburg' (Spider lily)
£4.89
Unit price perEstimated Delivery between January 10 and January 12.
Hymenocallis × festalis 'Zwanenburg' produces fragrant white, spidery flowers with a central cup, sending up dramatic flower spikes that add structure and summer interest to borders and patio pots. The blooms open progressively up the stem for a longer display and excellent cut stems.
Reaching an established height of around 50–70 cm, this bulb forms neat clumps of fresh foliage, then flowers in the warmest months when many spring bulbs have finished.
Plant in spring in a warm, sunny, sheltered position with well-drained soil. Work in compost to improve fertility and drainage, and avoid waterlogged ground, which can rot dormant bulbs or corms.
Water during dry spells while growth is active and feed every two to three weeks once buds form. Remove spent stems for a tidy finish, but leave foliage until it dies back naturally to feed next year’s bulb.
Ideal for borders, containers and cutting gardens, these spikes bring a slightly exotic note to planting schemes. In colder areas, lift and store bulbs once foliage yellows, or protect them well in a sheltered spot.

The bulbs arrived beautifully packaged and you could just tell they were excellent quality. We had the most wonderful display of daffodils this spring on our patio. Simply stunning. Will definitely be ordering again

I ordered the mixed hyacinth collection and the scent in my garden this April was absolutely heavenly. Every single bulb produced a strong, beautiful flower and the colours were stunning together. A fantastic purchase, I'll be back for more next year!
