I'm begging you - don't waste your money or time and hopes, on seed. Jacaranda can take 4-7 years from seed to flower, growing from seed is no guarantee of colour, form or vigour.

The only way you can get what you want, is to track down a supplier of a GRAFTED white form, and get some references cos I can tell you here in Australia I found it very hit and miss in the early days of these becoming available, and wasted a lot of money losing badly grafted trees.

And there only a couple of white ones in my local area that are anything to look at, I still think the purple are a superior one for flowering and vigour.

IMHO of course heh heh
