Hi Hamish, B. gregarii (-ii or -ia? The leaves are certainly prostrate.) B. natalensis B. radulosa These three are all small seedlings still and I am not having much luck in getting them moving. Perhaps compost not porous enough. Bring on to surface of compost even though still small? What temperature is best for the winter growth? Mine have to be in the greenhouse. B natalensis and radulosa are from summer rainfall areas and some gregaria's can grow in summer rainfall areas. B radulosa is in growth for me at present having appeared in early December. Yours are probably just dormant. Cheers, Rob in Tasmania
