I started a batch of Leuchtenbergia principis seeds on 8 May. I wasn't sure what percentage would germinate, so I started a lot (56, which isn't even half the number I got1). I noticed the first seedlings on 15 May, and new ones keep popping up. So I will soon have way, way too many baby Leuchtenbergias, with enough seeds to make way, way more.
So far, they don't look like much,
and
Leuchtenbergias are slow-growing plants besides, so they'll probably continue to not look like much for quite a while, but that's just a guess. In any case, things seem to be working as intended so far, so that's something.
Readers who have always wanted to grow a
Leuchtenbergia principis but have never been able to find one for sale (which I assume is probably most of you), let me know: I can probably hook you up with some seeds. I don't know how delicate the seedlings are yet, but mature plants are very easy to grow as long as you can supply them with adequate light.
2 Hopefully the seedlings won't be significantly harder to deal with.
