Welcome to the

 Speakers at Our Meetings

In January we had Arthur Katz tell us about 'Rare and Unusual Orchids' from all over the world.  He not only showed us fabulous pictures, but also explained why each one was rare and what made it unusual. 

His talk is on YouTube until February 20 and available to members.  Please email us for a link, STOSorchids@gmail.com.  Not a member? Join below.

At our February 21 meeting we will have Fred Clarke speaking on 'Cycnoches, Mormodes,  Catasetums, recent trends.' Be sure to check out the Orchid Opportunity below.
