Which Plants are Native to Washington D.C.?

 

Going with native plants for your garden is a great way to ensure the best results. As mentioned, any of these plants can easily thrive in the native soil and weather conditions. This hardiness means a lot less work for you and welcomes additions to the local ecosystem that provide reliable food and habitats for many birds and pollinating insects. Not only that, but native plants are the best at preventing soil erosion, and if you can plant any endangered varieties that might be native, you'll also be restoring a crucial part of the environment. Nurseries are your biggest ally when looking for local varieties, and we highly suggest consulting them as you get picking. Here's a few ideas to give you inspiration: 

 

 

Winterberry Holly (Ilex verticillata): Seen in many parts of the United States, this plant loses its leaves every fall and leaves behind clusters of bright red berries that are a great food source for the birds who love perching on its branches.

When Should I Plant My Garden in Washington D.C.?

 

 

Landing in Zone 7a of the USDA Hardiness scale, Washington D.C affords you ample opportunity for growing, where you can plant as early as February! You can also start seedlings indoors around this time. When April rolls around, it's the perfect month for annuals. Just be sure to check your area specifically since frost will vary by region.

 

Planting in Zone USDA Zone 7a

 

 

Zone 7 is split into two subzones, 7a and 7b, respectively. Their average winter temperature range is what sets them apart. 7a has a range of 0°F to 5°F, and 7b a range of 5°F to 10°F. With Washington D.C. being in Zone 7a, overwintering takes on a larger role in this region, and perennials are a great choice with their ability to endure harsher, colder months. Cold boxing and mulching will be an easy remedy for any significant dips in temperature, but such conditions are rare in the hospitable climate of Zone 7!
