The genus is divided pretty sharply into two groups - frost-hardy garden perennials grown for their flowers (mostly the Andersoniana Group), and tender tropicals grown for foliage.

The hardy types hybridise very easily and most of those cultivars are from seeds (selective breeding or volunteers). But the tropical types tend to be much less fertile in household conditions and seedlings are rare - so most tropical cultivars arise from sports or wild collections.

@TradescantiaHub @plants @houseplants I tend to forget about hardy sorts (not many for my climate, I think.- there was a nearly weedy one I saw in Toronto-still not my climate..lol- and I've heard of a few others, but never grown).

I'm partial to anything that will grow from seed, since there are few interesting plants available where I live-- things in mainstream commerce will make it to big stores here- and even mail order etc is limited as most U.S. and European sources don't ship to Canada!
