I agree Alberto, Leo's post is a good example of why I like this group so much: good information derived from personal experience! And I learned something, too. I have Sinningia tubiflora here, but it is not setting the world on fire. Now I know why: I should have it in the ground or in a very big pot. I should have guessed as much from seeing the really handsome plant Matt Mattus shows on his web site.
