Smithsonian Gardens

The one, the only, the classic AND iconic: Magnolia grandiflora, or more familiarly called the southern Magnolia. This southern staple is inescapable in the landscapes of the southern United States, and can also be found in home gardens up and down the east and west coasts. The scientific name is justified, because just LOOK at those stunningly massive blooms. Oh, did you get a whiff? They smell good too! But the southern Magnolia has way more to offer than showy flowers. This tree is large and regal with two-toned glossy leaves, which, did we forget to mention is evergreen? This tree has so much to offer ornamentally, ecologically (wildlife love those ruby colored seeds), medicinally for indigenous groups, and functionally in wood products. Keep in mind, this tree will routinely drop those big leaves and cone-like fruits for those who like tidier plants.

Shining bright in many of our gardens is Aquilegia chrysantha. Golden columbine is a native perennial that likes a shady garden space. The bright yellow flowers draw in hummingbirds and other pollinators.
