| Neutral | On Apr 30, 2012, vossner from East Texas, Direct sowed on March 8 and first bloom has appeared today. Not a very strong or pretty one but perhaps it will be better. The other seedlings don't look particularly strong, wondering if it is b/c I planted in less than full, brutal TX sun. It is very small, at about 8" tall. |
