Care Guide
Planting
Plant your Ground Rose in full sun to part shade, choosing a location with good drainage since this native thrives in well-drained conditions. Space plants about 2 feet apart if you're creating a groundcover planting. Spring is your best bet for planting, giving the plant the growing season to establish before any summer heat stress.
After Planting
Water weekly during your plant's first summer to help it establish a strong root system, then gradually reduce watering as it matures and becomes more drought-tolerant. Expect modest growth in year one - this is a naturally small shrub that tops out around 2 feet tall. Prune lightly after flowering (which runs March through August) to maintain shape and encourage bushier growth. The most common mistake is overwatering once established; this native prefers drier conditions, so dial back the hose once you see vigorous new growth.
