Coffeeberry
Rhamnus californica
Zones 7–13
Growing
When planting this woody shrub, focus on ensuring the soil remains well-drained, as it does not tolerate waterlogged conditions. While it is highly drought-tolerant once established, you can start your plants indoors or use cuttings to expand your collection. If you are working with limited space, this species performs beautifully in containers. For a more manicured look, consider the 'Eve Case' cultivar, which offers a more compact growth habit and larger berries, or 'Mount San Bruno' if you prefer a denser, more resilient shrub with smaller leaves.
Keep an eye on the midribs of your leaves for any unusual swelling. This can be a sign of galls caused by certain moths or midges, though these are common in the wild and often part of the local ecosystem. While the berries and foliage are a vital food source for many birds, livestock, and even larger mammals like deer, you may notice some grazing in your garden.
If you are looking for a way to suppress weeds or fill a large area, the 'Seaview' variety acts as an effective ground cover. When selecting your plant, look for the distinctive red twigs and prominent leaf veins that characterize the species. If you are planting in a landscape where you want to encourage wildlife, this shrub is an excellent choice for attracting pollinators and providing sustenance for migrating birds.
