Plantswoman extraordinaire, and long time OVRGHS member, Marilyn Light will be giving a presentation on her experimentation with starting seeds, including winter sowing.  This past winter she was more particular about recording her conditions with many different seed species obtained from OVRGHS, NARGS (North American Rock Garden Society) and the Ontario Rock Garden & Hardy Plant Society.  She was also able to obtain some interesting species including palm, conifer, tree/shrubs, as well as a number of different Apiaceae genera with which she is doing research for another project.  She's also working with species such as Allium, Aquilegia, Campanula, Erodium, Geranium, Dianthus, Silene, etc that do not require soaking so these were sown according to when she judged to be the best time.  She has been measuring the germinability under her conditions of the more than 125 species she's growing.  A good talk leading up to the OVRGHS seed exchange coming in Jan 2022.

​The Ottawa Valley Rock Garden & Horticultural Society (OVRGHS).
We are affiliated with both the North American Rock Garden Society (NARGS) and the Ontario Horticultural Association (OHA).


Our Society was formed in November 1992. Although the faces have changed somewhat since then, the objectives of the Society have remained the same: to promote and support "rock gardening" on a non-profit basis.

Over the years, we have built upon the solid foundation of the original group. We offer our members:

  • monthly meetings from September through May featuring local, national and international speakers,

  • periodic newsletters per year

  • an annual seed exchange,

  • spring plant sales each year,

  • garden tours and field trips,

  • workshops and demonstrations,

New members are always welcome.



Until it is safe to do so all planned meetings will be held by Zoom Video conference.  Zoom details for each meeting are sent by email or can be accessed on the members-only page
