Campanula Rotundifolia White Gem
This is the seldom-seen, pure white version of the true wild "Harebell" or "Bluebell-of-Scotland" and is a too-rarely-grown little gem. Long-flowering and easy to please in any position, it produces masses of dangling white bells on long thin stems over an extended mid-summer period.
Seeds can be sown at any time but are best sown in winter or early spring to benefit from a cold spell in the wet compost to break their dormancy. We advise covering seeds very thinly with sand or fine grit to about the depth of the seed size. If the seeds do not come up within 6 to 12 weeks the damp seed tray can be given cold treatment in a fridge for about four weeks. They may still take very many months to appear, so please never discard the pot or tray.
