    NARGS plans to create a feature to attract potential rock gardeners by posting on its website lists of plants that are easily grown and accessible. The list on NARGS will be linked to the ORG&HPS website, so that browsers can eventually become our new members. It is sometimes hard for a newbie to know where to begin: which plants are worth buying and trying to grow (with a reasonable expectation of success) and which plants are easy to find (either at local garden centers and nurseries, or online). For the plant lists to be optimally useful, users will need to be able to compare their own weather patterns and soils to those submitted by chapters around North America. Contribute your suggestions of 20 – or even more – plants along with whatever information you care to add about how you grow your plants by contacting Anna Leggatt or info [at] onrockgarden [dot] com (contact us).

Plant of the Month for May, 2017

 (kor-ID-ah-liss  SOL-id-uh)

General Information:

Corydalis solida is a great spring ephemeral that brings an unusual color to the garden at this time of year. How many of our spring flowers are red, pink or purplish red? Spread them around the garden between larger plants and enjoy them while the larger plants are still sleeping. By the time they grow to any size, C. solida will have gone underground for a summer snooze.
