I had mixed results with Farwellfruitfarm. I do not understand why he does not store his jaboticaba seeds in moist vermiculite like every other seller I've bought from. I wouldn't say don't buy any seeds from him (whenever he restocks his site with new seeds), but I had a lower germination rate from his jaboticaba seeds than from ones I bought here on the Forum from achetadomestica, Vernmented, and others.
So, add Vernmented to the list of good seed sellers. I've purchased rumberry (Myrciaria floribunda) seeds from Tang Tonic in the past. If you want to go through the aggravation of trying to germinate those, you will want to get them from him. I've never seen abimael777 offer seeds for sale, but he offers some very nice seedling plants at affordable prices.
