Growing

This resilient evergreen shrub is a powerhouse for filling in large gaps in your landscape. Because it spreads quickly using underground stems and runners, it is an excellent choice for controlling erosion on slopes and suppressing weeds in shady or partially sunny spots. It performs particularly well under trees, where its low-growing, prostrate habit allows it to carpet the ground without competing heavily with larger woody plants. When planting, aim for sandy or loamy soils that are well-drained to ensure the best establishment.

To keep the plant's growth manageable and tidy, you should cut it down each spring. This annual pruning helps maintain the shrub's shape and prevents it from becoming too unruly in your garden. While it is a hardy perennial that survives hard freezes, avoid placing it in areas with heavy foot traffic, as its delicate stems can be damaged easily.

If you are looking to expand your collection, you can propagate this plant using cuttings or division. Once established, the large yellow flowers will serve as a wonderful nectar source, frequently attracting honeybees and other pollinators to your garden.
