Tried and True Native Plant Selections for the Mid-Atlantic

New Fact Sheet!

Found in woodlands and on rocky slopes and ledges, evergreen Marginal Wood Fern provides year round interest. It is monomorphic so its fronds are virtually the same size and shape, whether or not their undersides bear sori, the spore-producing receptacles. Sori placement along the pinnule margins give rise to the species epithet and common name.

Climate-Conscious Gardening

Join Master Gardeners in the Arlington/Alexandria unit of Virginia Cooperative Extension in a series of monthly articles in 2021 as we explore the topic of climate change and practical actions individuals can take in their home landscapes in response. 

By Elaine Mills, Extension Master Gardener

In February, we discussed garden practices that could directly help to mitigate the effects of climate change. This month, we consider a set of adaptive strategies that gardeners can take to improve their soil.

According to Dr. Sara Via, Climate Extension Specialist at the University of Maryland, maintaining the health of our soil is the primary strategy for climate resilience. As the second largest ecosystem after the world’s oceans, soil not only provides physical support of our plants, but also is crucial in the cycling of water and nutrients. In addition, it provides habitat for a multitude of living things, including beneficial microbes that develop special relationships with plants. Continue reading →

This word, related largely to ferns, usually appears in the plural, ramenta, and often with the modifier “chaffy,” as above. Chaff is the covering that is winnowed away from wheat after harvesting the grain, leading to the proverbial “separating the wheat from the chaff” – distinguishing between what is valuable and what is worthless.
