i've only tried a few plants. i've had some success with phalaenopsis from home depot but only wgen taking the original cutting from a new leaf or new root growth that's all i've done as far as orchids go. i've had success with cati and suclent and experiments with some random trees. some times the vials do get infected no matter how hard you try. it's one of those things that just happens. i'v heard u can use the kit to sprout orchid seeds
