The May issue of Digger has been mailed to subscribers, and the cover story this month is on plants with a stunning silvery look (PDF). From agaves to Japanese painted ferns, plants with silver hues not only make a striking impression in the landscape, their color also often represents survival tactics such as drought tolerance and pest resistance.
