Titamopsis primosii: first flower (3 pics)

Before I write a post on all the showy Delosperma flowers from my balcony I wanted to show you this one which is much more special to me. I grew this Titanopsis primosii from seed and am now very proud it has managed to grow such a large and beautiful flower. Or to bloom at all. The plant itself is quite tiny and I really wonder where it got the strength. After all, my grown up Titanopsis promisii have never ever flowered for me. 

It has been flowering for a week now but I couldn't see it as it only opened for a short time in the afternoon. Yesterday I could finally arrange a photo session with this beauty.

So, looks like I've raised this one to adulthood :)

There was a flower on another seedling of this bunch but I either missed it or it never opened so I'll consider this one as the first. It seems like a miracle! I've grown it from a seed collected from my own plant and now it's flowering!

You can see these Titanopsis calcarea plants as newborns, nearly newborns, 2-month-olds, 3-month-olds, 15-month-olds here in the blog. They hatched in May 2013.

Do you have any advise or explanation? I can't figure out what these guys are missing. They've been starting flowers, then drying them off and replacing them with leaves... And then start all over again. It's been going on for so long with both seedlings and my adult plant that I've come to see it as normal. Still, I'd really like to actually see the flowers develop and open someday. I water them well (no fertilizer since months though).
