Native Plant of the Month: Boneset
Common boneset (Eupatorium perfoliatum) is a hardy perennial native to NoVA, frequently growing wild in damp soils near stream banks, floodplains, and wet meadows. Featuring dense clusters of small white flowers that bloom in late summer through fall, it serves as a critical late-season food source for local pollinators like native bees, butterflies, and beneficial wasps. Its name doesn't come from fixing broken bones directly, but rather from its historic use as a herbal tea to treat "breakbone fever" (a severe dengue-like flu that caused intense body and muscle aches). Visually, the plant backs up this unique name - its opposite leaves are joined at the base so completely that the stem appears to grow right through the middle of a single, continuous leaf, as if the foliage itself had "set" together around the stem.

Horticultural Tip of the Month: Leaf Litter Habitats
During autumn, the dense canopy of native hardwoods drops a thick, vibrant carpet of leaf litter across suburban yards and forest floors. Rather than just lawn debris, this fallen layer acts as a vital natural mulch that retains soil moisture, prevents erosion on local slopes, and returns key nutrients like calcium and nitrogen to the soil as it breaks down over the winter. Leaf litter isn't just dead foliage - it is also a cozy winter hotel. Up to 94% of native moth and butterfly species in the mid-Atlantic region (including species like Luna moths and Eastern Tiger Swallowtails) spend the winter tucked inside fallen leaves as pupae, eggs, or caterpillars, relying on the unraked leaf layer as thermal insulation against freezing temperatures.

Invasive Plant of the Month: Creeping Jenny
Creeping Jenny (Lysimachia nummularia) is an invasive perennial ground cover in NoVA, originally introduced from Europe as an ornamental landscape plant. Thriving in moist, low-lying habitats like stream banks, wetlands, and damp suburban lawns, its trailing stems form dense, suffocating mats that root continuously at every leaf node, effectively crowding out native vegetation and altering local ecosystems. Creeping Jenny is also known by the traditional common name moneywort. Its Latin species name, nummularia, comes from nummulus - the ancient Latin word for a "small coin" - a nod to the plant's pairs of small, smooth, rounded leaves that resemble long strings of golden or green coins trailing across the ground.
