Cambs and Beds HPS Conservation Scheme
Nationally the HPS runs a conservation scheme to save cultivars of hardy perennials, that are in danger of possible extinction. This could be for many reasons, ranging from changing tastes to difficulty in growing on for the retail trade. It would be a shame to lose many of these plants for posterity and therefore a group of us here at Cambs and Beds do our best to propagate and disseminate these plants every year.
All members are welcome to join in. A list of conservation plants can be found on the national website, and anyone wishing to join, just let me know what plants you would like to propagate and I will endeavour to supply them.
For those who have plants I have designed a table, which is just a quick go-to, to show the method and time of year for propagation of our conservation plants.
