Use Lysimachia lanceolata 'Burgundy Mist' when you want a bold foliage accent that also flowers reliably in summer. This lance-leaved loosestrife makes a low, spreading planting that shows off deep burgundy leaves through the growing season, then adds bright yellow, star-shaped blooms in summer for high contrast.
In your garden, place it where you can enjoy the color up close along the front of beds, in mixed borders, or as a small-scale groundcover weave among other perennials. It typically reaches about 12-24 inches tall at maturity (flowering stems included), and it spreads to form a wider patch over time, creating a unified look when planted in groups.
For best performance, give it full sun to part shade. More sun generally brings stronger color and fuller flowering, while a bit of afternoon shade can be helpful in hotter locations. Provide average to consistently moist soil, especially as it establishes, but aim for good drainage. Once settled, it handles a range of garden soils and is a good fit for spots that are not bone-dry. Mulch lightly to keep the root zone even in temperature and moisture, keeping mulch off the crowns.
Maintenance is simple: cut back spent stems after flowering or tidy the plant in late fall or early spring before new growth starts. Divide clumps if you want more plants or if the center becomes crowded. Pair it with other sun to part-shade perennials that appreciate similar moisture, letting its burgundy foliage echo darker leaves or contrast with brighter greens and silvers.
