WaterRock rose prefers to be watered deeply but infrequently. Depending on the weather conditions, watering should be done when the top inch of soil appears dry, typically once every week or two. Give the plant a thorough soaking, targeting the root zone, until you've applied about half a gallon of water per plant. During the hotter summer months or in dryer climates, you may need to increase watering frequency. Over-watering or letting the plant sit in waterlogged soil can lead to root rot, so ensure good drainage.
LightRock rose thrives in well-lit environments and should be placed in a location where it can receive full sunlight for at least 6 hours a day. The best spot for this plant is a south-facing garden or a window if grown indoors. Too little light may cause the rock rose to become leggy and affect flowering.
TemperatureThe rock rose is a hardy plant that can tolerate a wide range of temperatures but prefers conditions between 60 and 80 degrees Fahrenheit. It can survive minimum temperatures down to around 10 degrees Fahrenheit but should be protected from prolonged frost. The ideal environment is a temperate one without extreme heat or cold fluctuations.
PruningThe rock rose should be pruned to maintain shape and encourage bushier growth. Pruning is best done after the plant has finished flowering, usually in late spring or early summer. Remove any dead or damaged branches and lightly shape the plant to your preference. Regular trimming helps to promote new growth and prevent the plant from becoming woody.
CleaningAs needed
SoilRock Rose (Helianthemum 'Wisley Primrose') thrives in a well-draining soil mix that is light and gritty, with a mix of sand, peat, and loam being ideal. The pH should be slightly acidic to neutral, within the range of 6.0 to 7.5. Amend the soil with organic matter to ensure proper nutrient content and drainage.
RepottingRock Rose should be repotted every 2 to 3 years to refresh the soil and accommodate root growth. Repotting in spring is ideal, allowing the plant to establish in the new container before the growing season.
Humidity & MistingRock Rose prefers a dry to moderate humidity level; they do not require high humidity. Ensure good air circulation to mimic their natural Mediterranean environment.

Life cycleThe plant Helianthemum 'Wisley Primrose', commonly known as the Rock Rose, begins its life cycle when seeds are sown in well-drained soil and germinate, typically in early spring. After emerging from the soil, seedlings will develop into young plants with sets of true leaves, and they establish a healthy root system. As temperatures warm, Rock Rose enters a rapid growth phase, forming dense, woody stems and evergreen foliage. During late spring to summer, the plant produces abundant yellow primrose-like flowers, attracting pollinators and often blooming continuously for several weeks. After flowering, seeds develop and are subsequently dispersed, either by natural means or through collection for propagation. During winter, the Rock Rose becomes dormant, revealing its hardiness by withstanding colder temperatures and regenerating for the next growing season.
PropogationPropogation time
Spring to early summer
The Helianthemum 'Wisley Primrose', commonly known as Sunrose or Rock Rose, is most effectively propagated through semi-ripe cuttings taken during summer. One begins by selecting a healthy, non-flowering shoot and cutting it to a length of about 2 to 4 inches (5-10 cm). The lower leaves of the cutting are then removed, and the base is dipped into a rooting hormone to encourage root development, although this step is optional. Subsequently, the prepared cutting is planted in a well-draining potting mix, ensuring that the leaf nodes where leaves were removed are covered by the soil. The cutting should then be placed in a warm environment with indirect light and kept consistently moist. Roots typically begin to form within a few weeks, after which the cutting can be potted on or eventually planted out into its final position.
