Once again, the event that all Orchid Lovers in the DC Metro area have been anticipating ~ ~ The National Capital Orchid Society is holding its Annual Show and Sale on February 15 through 17 (Sat. thru Monday, President's Day weekend) at Homestead Gardens, 743 Western Central Ave., Davidsonville, MD 21035.

This is a bit further from the center of the Washington metro area than the show has been in the past.  It is approximately a one hour drive from the intersection of I-270 and the DC Beltway.

This event is free to the public.  We will have:

  • A display area with exhibits from other orchid societies in the mid-Atlantic region.  There will be hundreds of blooming plants on display.
  • A vendors area with plants for sale.  More information about the vendors is listed below.
  • Tours of the exhibit space.
  • Educational talks on how to grow many of the popular types of orchids in your home.
