These plants have a seasonal rhythm in nature, growing submersed in the river during high water level and drying out on the banks
at low level for months. The plant flowers and survive with new small leaves. Cryptocoryne crispatula var's balansae, flaccidifolia and tonkinensis grow the whole year submerged and keep their long leaves. Cryptocoryne crispatula var. kubotae submersed in an aquarium holds its long leaves (forever?).
For reference to the other plants and more literature see the page on the crispatula group.
