Please join our October guest, Carol Klonowski for a presentation on Deciduous Dendrobiums.  Dendrobiums are the second largest genus behind Bulbophyllums. Essentially there are two types of Dendrobiums, evergreen and deciduous. Carol’s talk will focus on the latter and their particular cultural needs within this diverse genus. Decidious Dendrobiums include: anosmum (superbum), Den. aphyllum (pierardii), Den. parishii, Den. nobile, Den. signatum, Den. albosanguineum, Den. moschatum, Den. fimbriatum, Den. primulinum, Den. pulchellum, Den. senile, Den. unicum, just to name a few. Deciduous types require a definite dry winter’s rest and a dormant period in order to initiate their bloom cycle for the following spring.

Carol will also discuss the care of other (evergreen)  dendrobiums that we commonly have in our collection. There will be something for everyone to learn from and prepare their dendrobiums for glorious spring blooming. Come…learn…and be inpowdered !

About Carol

Carol has been growing orchids since the 1980’s when a friend in Berkeley, California, gave her a cattleya and it bloomed out with three big, dark lavender flowers and an intoxicating fragrance.  She built an entire greenhouse in her backyard to accommodate the precious plant, which only led her to buy more orchids.  Then another friend gave her a gift membership to the Orchid Society of California and it’s been a serious hobby and passion ever since. She can recall going to monthly orchid society meetings where orchid legends such as thimg_1034e late Frank Fordyce would be available to answer the many questions an eager hobbyist could ask.

 Carol has served as Director, Vice President, and President of the Orchid Society of California for most of the past two decades and is currently a Fully Accredited Judge  with the American Orchid Society, California Sierra Nevada Judging Center.
