- MarkVerified ReviewerRated 4 out of 5 starsNov 16, 2025Great for grafting
I bought some of these about 3 or 4 years ago before Botanical interests prices increased so much. I had about 90% germination and about 60% of the grafts took. I'd say that is pretty good! I miss shopping at Botanical Interests, but to be honest they are pricing themselves out of my budget. They do have some neat seeds, and these were a cool experiment.

Thank you so much for sharing your experience with these — a 90% germination rate and 60% graft success is fantastic, and we’re glad the experiment was a fun one for you!
We completely understand concerns about pricing. The cost of our seeds is directly tied to the incredible work our partner farmers put into producing varieties that meet, and often exceed, strict USDA standards. Growing high-quality seed requires significant time, labor, and resources, and while we do everything we can to keep prices accessible, we also want to ensure you’re receiving the best possible quality.
We truly appreciate your past support and hope you’ll continue to explore with us whenever it fits your budget. Thank you again for taking the time to leave such thoughtful feedback. Keep on growing 🌻️

The fortamino packet said it contained 10 seeds with likely 80% germination, but mine actually had 11 seeds and 100% have sprouted! Very excited to see what happens with my first attempt at grafting this season

These seeds are not good. Do not recommend. I grew them exactly according to instructions on packet, with adequate heat from a heat mat, and supplemental uv lamp. I also used pots from epic gardening to grow these. They are weak seedlings, falling over, molding. My heirlooms look 100x better. I have no idea how these could support grafting, it was a waste of $10. Save your money!
