Lachenalia
Lachenalia is a genus of bulbous perennial plants in the family Asparagaceae, subfamily Scilloideae, which are usually found in Namibia and South Africa. Most of them have a dormancy period, but new roots will always grow every year.
Lachenalia is named after the Swiss botanist Werner de Lachenal. Species are sometimes known as Cape cowslip, though they are not even somewhat related to the true cowslip Primula veris.
