There is the mini firefly series that was put out a couple of years back. Plants are small as well as flowers. Glasshouse works has some of the mini Hawaiian that were out about a decade or more and look like multi colored flowered firefly. Both of these are said to be wallerianas but they seem just to small they may be true hybrids of them though. If you like species repens is a good choice though it is prone to damp off sometimes. Its from Shri-Lanka it has red leaves and big yellow flowers. In my collection, I have the African sp. bequartii with bronze spade like leave and tiny white star-like flowers. I am currently nursing this plant along I almost lost it this winter.

Could any one tell me where to get the mini firefly series.
i have been looking for some time for real small impatiens Thanks so much TOMD63

I havent seen the fireflies for a couple of years myself. Glasshouse works has the mini Hawaiian which are the same for the most part. Kartuz's Greenhouse may have some I know he has them as stock they may be in his catalog they were last year.
