Commelina

I think that the advice Thompson & Morgan give is probably as good as any http://www.tmseeds.com/product/1421.html

I used to grow them on my "rubbish dump bank". The soil was well drained (with all the rubble and rubbish underneath) and they thrived, but need to be treated as annuals really. I loved them and excitedly went every morning to see the new flowers each day, opening from their little 'lockets'. I too have found it difficult finding them. I didn't grow seeds though, but always bought the corms. I'll get some friends & relatives to look and let you know if there's any luck.

i used to gorw commelina coelestis,the blue spiderwort. iloved it. keepfor yeers in pots and grenhouse forwinter.
sow seed 20°C
Lightly Cover
Sow spring outdoors or earlier under glass
May flower in 1st year from early sowing.mineusual 2nd yeert

Kept both the blue and the white going for a long time n a south facing warm bed, but the last winter did for them. Thought that was it, but they have self seeded all over the place. So I dug some up and they are going in the greenhouse for winter this time.
Also I have collected a few seeds of each in case.

They are also beloved of slugs and snails
