Crinum Amabile, White Giant Spider Lily 10 Bulbs Crinum Amabile, White Giant Spider Lily 10 Bulbs This is a specimen crinum lily. The foliage as well as the bloom are stunning. And they seem to bloom as long as it is warm. The Giant crinum lily or giant spider lily, is a huge lily. Some would say spectacularly huge lily and they would be correct. It grows to over 5' high with 5' long sword shaped leaves. We see them most often in south Florida and other tropical or semi-tropical regions. In northern Florida they will freeze back to the bulb during winter then spring to life in the late spring. Much like an amarilus bulb. The giant crinum lily is a great specimen plant for a large, dramatic accent in a tropical garden.
