Paphiopedilum stonei is a large multifloral species from Borneo. This is a notoriously slow species to grow from flask. It is even slower than Paphiopedilum sanderianum. However, once they are up to blooming size they are usually reliable growers and bloomers.
An interesting (and frustrating) tendency of this species is that it will often put up a sheath a year or more before developing a flower spike. the flowers are worth the wait as they are quite striking.
Give this species warm temperatures and bright light and it will grow well. We have more details on growing multifloral Paphs on our care page.
