Tiny cactus, again

Remember last winter, when to help fend off the I-can't-do-much-gardening doldrums I planted some cactus seed, and raised several tiny cactus? It certainly was fun and interesting, but as you may also remember I ended up giving those spiny seedlings away -- they were not cold-hardy varieties and I don't have room for overwintering more indoor plants. Especially the potentially painful ones.

What I didn't tell you is that last spring I ordered some cold-hardy cactus seeds, and a few months ago I sowed them. Here's an update on a project that you didn't even know was taking place.


I have no idea what species I have here yet, but they definitely look different than the previous batch. I've got at least three different varieties here.

I suspect I'll be able to identify these once they get a bit larger.

I think there were about 15-20 seeds that I sowed, but only about half a dozen have germinated.

So far that is. I suspect some of them may take quite a while to wake up -- a year or more!

I believe this one just recently germinated:

I'm not sure how long I'll leave these in the little tray they call home, as it doesn't have drainage holes. It definitely can't go outdoors as-is.

For a sense of scale the inside of this tray is about 5" (13cm) wide.

Perhaps I'll just drill some holes in it -- might be less traumatic than repotting each of these. We'll see though.

So I've got small spiked seedlings to care for again. Fun!

I wonder how large each of these will eventually get?

How exciting. Did they tell you what might be int he packet? WHat medium did you use. Spines so early in their life is amazing. How long to germination. I have an outdoor hedgehog cactus which produced masses of seeds this year but they are still encased in the fruit. I removed some and tried to dry them out. Very sticky. Just planted them a few minutes ago so your post was timely. I would love to have more of this cactus because it is cold hardy and produces masses of yellow flowers.

They look great! I'd drill holes in the tray and leave them in there until they're at least a couple of inches tall.

Of the ones you sent me, only two are still alive. I overwatered the others :-(.

L rose: They did not list what the species could be. The first ones germinated pretty quickly -- a few days to a week or so if I remember correctly. They produce spines so early, it really amazed me too when I first saw it.

Gerhard: two is probably a better survival rate than they would have had with me.

So Cute! Especially the one in the 3rd and last picture, just a perfect little miniature!
