I've ordered many different types of seed from them over the past few years, mostly small packets of palms, fruits, & various ornamental plants. Successful germination has been mixed with some having nearly 100% germination and some zero. They do receive seed from all over the world and are dependent on the supplier for proper ID and handling, but I believe they try to be truthful about what they sell. That said, some plants just have very very short periods of viability (like cyclanths), or painfully slow germination rates (like some palms), so the buyer has some responsibility to research what they are trying to grow. I will give RPS credit for making many previously rare seeds available, and I'll continue to purchase from them.
