This presentation is based on a trip that my wife (Lynne) and I took to Australia in September 2015. Western Australia has more than 400 orchid species and dozens of subspecies and natural hybrids. 100% of those are terrestrial and therefore tend to be much different than the orchids that we commonly associate with Australia (or grow in Northern California), such as Dendrobium, Sarcochilus and Phaius. Generally, the orchids of Western Australia have symbiotic associations with Mycorrhizal fungi to benefit their plant growth and development, often required throughput the entire plant life cycle, not just for seed germination and early growth phases. As a result, these plants are rarely seen in cultivation, even in Western Australia.

Dale MartinDale got the orchid bug in his early teens in Phoenix, but after moving to the Bay Area in 1976 he became acquainted with Rod McClellan’s orchids, and soon his kitchen window was brimming with orchids. A move to Santa Rosa in 1989 afforded an opportunity to house his rapidly growing orchid collection in a backyard greenhouse. In 1999, he and his wife completed construction of a new greenhouse and home in Petaluma. Austin Creek Orchids was established in 2001. In the past few years, he has focused largely on Paphiopedilums, although he grows many other genera including Angraecum, Bulbophyllum, Cattleya, Dendrobium, and various Vandaceous species and hybrids.
