Brook Klehm asked about growing Knowltonia (Ranunculaceae, from South
Africa) outdoors in the PNW. The Heronswood Nursery catalogue (i.e. Dan
Hinkley) suggests that K. capensis is growable outside in the Seattle area
'we have cultivated it much longer in our woodland at Heronswood. ... in
partial shade and evenly moist soil, or in containers.' As Jane said,
however, the microclimate at Heronswood is exceptionally favourable.

Inspired by Dan's enthusiasm I planted my only specimen in the ground at my
parents' garden in Maidenhead (near London) a few years ago, but it has
dwindled to one leaf which I came across the other day & wondered what it
was before remembering. On that experience I couldn't recommend growing this
demurely charming plant outside in southern England.
