    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).

General Information:

It is difficult to find plants for dry shade but Pachysandra procumbens will be quite happy in such conditions, at least in cooler climates. In warm areas you might need to provide more moisture.
