Campanula 'Warley White' (Sometimes known as C. warleyensis)

What a riot of clarity, colour-wise, from early February. A stunning bold, yet small plant absolutely smothered with double pure white blooms up to 2cm across. Some say that it should have a little shade or protection form frost. It is dormant in winter, but can have a growth spurt on a hot day, a few of these over winter will exhaust the plant. Only 15cm or so tall overall. Easy and delightful. RHS AGM and deservedly so. I love it. In production, but a month or two.
