reproduce naturally by
means of seed which germinates readily under ideal

be propagated vegetatively by splitting the bulb and by subdivision as well as from seed.

Suitability as Green Roof plants
plants are valuable in combination with other plants that do
not have a
very vigorous nature to both increase biological diversity as well as
for their staggeringly beautiful flowers.
