I'm not sure how to frame this question, but since Cardamine laciniata is the only one I am familiar with,

are all cardamine species ephemeral?

Any experience with self fertility/infertility?

All Cardamines I have are more or less ephemeral. However, if the summer is moist some of them keep their leaves for a long time.

C pentaphyllos, enneaphyllos and waldsteinii seem to be self-incompatible as they never or seldom set seed (have only one clone of each). Heptaphylla sets plenty of fertile seed and bulbifera sets lots of bulbils. Pratensis is so common that they always produce seed and even parts of leaves and stem can root.

Rogaland, Norway - with cool, often rainy summers  (29C max) and mild, often rainy winters (180 cm/year)!
