Aftercare
Allow the foliage to die back naturally after flowering so the bulbs can replenish their energy for the following season. Remove spent flower heads if you prefer a tidy appearance, or leave them in place to provide attractive seed heads that extend seasonal interest. Established bulbs can remain undisturbed for many years, where they will continue to produce reliable spring displays.
