Breeding

OBSERVATIONS

The first thing you must realize is that you cannot practically expect to cross any species with any other, for the following reasons: * 1. Different numbers of chromosomes. This barrier alone cuts the number of possible crosses in half. * 2. Different flowering times. When the flowering period of Campanula bellidifolia is over, Campanula lasiocarpa begins, and later Campanula piperi. Unless you adequately save and store the pollen, or force a plant to bloom at a different time than it would normally, you cannot make some crosses. (To store pollen, put it in glassine envelopes, then in a jar containing about 1/4 inch of silica gel. Cover tightly and refrigerate.).8)

Very attractive low-growing plants (10-30 cm) from the alpine zone of mountains, growing on rocks and scree. Uses: rockeries.11)

Living

From the alpine zone of mountains, growing in the cracks of rocks in the middle and alpine zones. Uses: rockeries. 12)
