WaterThe Rock Rose (× Halimiocistus wintonensis) prefers a moderate watering schedule, ensuring the soil is partially dry before the next watering. During the active growing season in spring and summer, water the plant once every week with about 1 gallon of water, depending on the size and the pot's drainage. In fall and winter, reduce watering to every two to three weeks, as the plant enters a dormant period. Overwatering can lead to root rot, so it is crucial to check that the pot allows for proper drainage.
LightRock Rose thrives in full sunlight and should be placed in a spot where it receives at least 6 to 8 hours of direct sunlight daily. Avoid shaded areas, as insufficient light can hinder flowering and growth. A south-facing garden spot or window is ideal to provide the necessary sunlight for this plant.
TemperatureRock Rose enjoys temperate climates and performs best in temperatures between 50°F and 75°F. The plant can tolerate occasional dips below freezing, but prolonged exposure to temperatures below 20°F may damage or kill the plant. Ideal growth conditions are achieved when nighttime temperatures are cooler than daytime temperatures.
PruningPruning Rock Rose is important to maintain its shape and encourage denser growth. Prune in late winter or early spring before new growth begins, removing any dead or damaged branches and shaping the plant as desired. Avoid heavy pruning; instead, focus on light trimming to keep the plant healthy and well-groomed.
CleaningNot needed
SoilThe Rock Rose (× Halimiocistus wintonensis) thrives in a well-draining, sandy loam with added gravel for improved drainage. The ideal soil mix is one part sand or grit to two parts standard potting compost. The plant prefers a slightly acidic to neutral pH, ranging from 6.0 to 7.5.
RepottingThe Rock Rose should be repotted every two to three years or when it outgrows its current pot. It is best to repot in the spring just before the growing season begins.
Humidity & MistingThe Rock Rose prefers average to low humidity levels and can tolerate dry atmospheric conditions. It is well-suited for typical indoor humidity levels and does not require additional humidity.

Life cycle× Halimiocistus wintonensis, also known as rock rose, begins its life as a seed that germinates in well-drained soil during the warm season. Once the seedling emerges, it focuses on developing a robust root system and foliage through the juvenile stage. As it matures, the plant enters a vegetative stage, forming a woody base and branching structure supportive of its flowering capacity. The adult rock rose blooms in late spring to summer, producing showy, saucer-shaped flowers that attract pollinators. Following pollination, the plant sets seed, which is then dispersed by various means, including wind and possibly wildlife. In, its perennial nature allows the rock rose to repeat the flowering and seed-setting cycle for several years, with individual plants living a decade or more under optimal conditions.
PropogationPropogation time
Spring-Early Summer
The Rock Rose (× Halimiocistus wintonensis) is most commonly propagated through semi-ripe cuttings taken in late summer. To propagate using this method, a gardener should select a healthy stem that is not flowering and cut a piece approximately 4 to 6 inches (10 to 15 centimeters) long just below a leaf node. The lower leaves are removed, and the cut end can be dipped in rooting hormone to encourage root growth. The cutting is then placed in a pot filled with a mixture of peat and perlite or a similar free-draining propagation medium. The pot should be kept at a consistent moisture level but not waterlogged, and placed in a warm spot with indirect light. Roots typically develop within a few weeks, after which the new Rock Rose plant can eventually be potted up or transplanted outdoors once it has grown sufficiently and the risk of frost has passed.
