SAN FRANCISCO (KGO) --Explore the Legacy of Orchids at the 64th Annual Orchid Exposition in San Francisco.
Orchids are one of the oldest plant species and date back thousands of years. Their legacy and importance in society throughout history have been noted in the Aras Pacis of Ancient Rome and in the Materia Medica, which is the oldest known Chinese pharmaceutical text.
The Pacific Orchid Exposition boasts over 150,000 beautiful orchids from around the world and features docent tours, orchid potting demonstrations, cultivation tips and a diverse array of orchids for sale.
The event showcases intricate exhibits from local, national and international orchid growers, as well as vibrant displays from Orchid Societies around California.
Plus, throughout the weekend there is a silent auction featuring fabulous items to bid on like wine, art, trips, and more.
The 64th Annual Pacific Orchid Exposition runs February 26 through February 28.
Orchids for Bay Area's microclimates:
1) Phalaenopsis are low-light orchids and will thrive in a east window, or a shaded southerly or westerly exposure. They do not like direct sunlight and will scorch.
2) Cymbidiums have been known to briefly withstand freezing temperatures, although frost will kill them. They can also withstand considerably summer heat without wilting.
3) Milltonias survive best with indirect light and some shade in the middle of the day. Too much direct sunlight will damage these orchids' leaves.
4) Masdevallias require very cool conditions and abundant moisture throughout the year. They cannot tolerate dryness, low humidity, or excessive temperatures and the plants are very easy to kill.
5) Lycastes perform best with temperatures between 60 and 80 F, though they will tolerate slightly higher or lower temperatures for short periods.
6) Cattleya occineas grows best in areas that are on the warm and dry side and it's best to grow in pots.
7) Laelia anceps are very durable plants. They easily take temperatures down to freezing or as warm as the 90's.
8) Dendrochilums prefer very bright light just short of direct sunlight. The thinner the leaf, the more sun the plant will tolerate.
