The tree species in the genus are fully hardy. A.x carnea seedlings make better stocks than A. hippocastanum, which is too vigorous and forms a poor union, except with its own cultivars. Gather ripe conkers when they fall to the ground. Remove the husks;sow at once. Alternatively, store in moist peat at 3ºC, then sow individually in pots in midwinter.
