holds plant sales in May at a booth at the Rare and Unusual Plant Sale and sometimes in September.
These are open to the public. The plants are raised and donated by our members.

This is a unique opportunity to acquire many plants that are infrequently available through the retail market at very reasonable prices. A particular advantage of acquiring unusual plants through these sales is that the donor/grower is frequently present to speak to growing requirements. From time to time, there are rock gardening accessories and books on offer as well.

Proceeds from the sale help to defray the expenses incurred in bringing expert speakers in from across North America and Europe.

Our annual seed exchange gives our members access to many rock plant species that are not widely available through regular channels.

The OVRGHS seed exchange process is simple. Since our members collect the seed from their own gardens, each species offered has survived in our local conditions. We publish an alphabetical list of all the donations, often with short germination hints and always with height and colour information. For a small participation fee, members can then request seed from the published list.
