✂️ Care

Water regularly to maintain moist but well-drained soil, especially during growth and flowering. Stake the stems to support the majestic flower spikes. Remove spent flowers as they wilt to encourage prolonged and abundant blooming.

Lightly prune after the first wave of blooms to stimulate a second flowering in late summer. In autumn, cut the stems back to the ground once they have completely died back to promote vigorous regrowth the following spring.
