Rainy Side Notes

A few years ago, Corydalis flexuosa 'Purple Leaf' was an exciting addition to my garden. I planted the small perennial into a new rock wall, so when the plant departed into dormancy during the summer, it didn’t leave a gaping hole in the garden.

In late winter to early spring, the leaves are purple, and at the base of each leaflet are dark red markings. In spring, it is the first Corydalis flexuosa cultivar to flower; the glorious blue flowers are very striking against the charcoal-gray basalt rocks that make the wall.

Unlike many other areas of the country, we can grow these beautiful perennials in our maritime climate, since the species come from cooler climates. However, it is important that corydalis be planted in soil with excellent drainage.
