I frequently order from Tradewinds Fruit.
I have had a good experience overall. They are pretty flexible with things, if any issues arise.
My experience:
I prefer to order recalcitrant seeds (short shelf-life seeds). They are more likely to be fresh when you get them, as some seeds have zero to poor germination rates. The seeds are generally priced nicely so there isn't much lost if germiantion issues occur.
I like to frequent their site to check out whats new. Newly introduced seeds generally are more likely to successfully germinate.
Most seeds seem to benefit from 1-2 soaking in warm water, and a dip in fungicide to prevent rot. Sandy well-draining soil is highly recommended.
Here's an extensive list of genera and species I have successfully germinated (Of course I don't still have all of these :/
Annona: reticulata (poor), squamosa (poor), purpurea (excellent)
Aristotelia chilensis - Maqui Berry
Artocarpus lingnanensis- Kwai Muk
Bromelia pinguin
Carica
Clausena wampee - Wampee
Coffea
Dovyalis (poor germination)
Eugenia (exellent)
Flacourtia (poor-decent germination)
Garcinia: hombroniana, intermedia, madruno, xanthochymus
Inga
Lansium domesticum
Monstera deliciosa
Muntingia calabura
Passiflora: incarnata (excellent), laurifolia (poor germination), mollissima (good-excellent) , nitida (excellent), tarminiana (excellent), quadrangularis (Passiflora seeds here are iffy, but not too pricey, so its worth it)
Physalis
Psidium eugeniaefolia (poor germination)
Psidium guajava- Waiakea & Colombian Red Guava
Rollinia deliciosa
Rubus niveus - Mysore Raspberry
Syzygium oleosum - Blue Lilly Pilly
Hope this helps!
