Ranunculus calandrinioides

Ranunculus is an amazingly varied genus and I have a bit of a thing for them. This is one of the species found in the Western Mediterranean region with glaucous elliptical leaves (almost like a small Hosta) and gorgeous white flowers, slightly pink tinted. This species (from the Atlas Mountains of Morocco) is winter green and winter flowering, and although cold-hardy, is not generally recommended for outdoors. Perfectly easy in a pot in an unheated greenhouse, kept dry in summer but well watered and fed when in growth.
Ranunculus platanifolius

A very easy and adaptable, and frankly just very lovely white flowering buttercup. Fresh and easy, and did I say lovely? Suitable for any retentive soil in sun or semi shade. Not even slightly invasive.
