It is only with the support of our sponsors that the Horticultural Society of Maryland is able to bring high quality educational programming through lectures, tours, seminars, workshops and a newsletter to its members and guests at all levels of interest in horticulture. Programs include our perennial favorites such as the monthly Lecture Series (seven lectures annually with an audience of approximately 200 gardeners, landscape designers, and horticulturists), the Plant Forum, and the Annual Garden Tour. In February, we will again partner with the Perennial Plant Association to co-sponsor their Mid-Atlantic Regional Seminar.

The Horticultural Society of Maryland, Inc. is a 510-c-3 non-profit organization and donations are tax-deductible to the fullest extent of the law.
