The simple answer: Yes, but...Orchid seed is very fine and dust-like, without the nutritive endosperm present in almost all more-commonly-grown flowering plants. For this reason, orchid seed can only be grown under a very specialized set of conditions usually beyond the capability of home growers. Orchid seed must be grown in a sterile culture, not unlike that used in hospitals. If you are willing to put the time and effort into this process, not to mention the three or more years required before your plants would flower, it is certainly one of the most interesting aspects of orchid culture. On the other hand, with orchids so reasonably priced these days, why not just get flowering size plants and let the experts do the work for you?
