WaterThe Rock Rose should be watered deeply but infrequently, allowing the soil to dry out slightly between waterings. This could mean watering approximately once a week during hot, dry periods, with less frequent watering during cooler, wetter seasons. Generally, applying about one to two gallons of water to the base of the plant, depending on its size and the soil conditions, should suffice. Over-watering can lead to root rot, so it’s crucial to ensure good drainage and not to let the plant sit in waterlogged soil.
LightRock Rose thrives in full sun conditions, which means it should receive at least six hours of direct sunlight daily for optimal growth. It performs well in a south-facing garden where it can bask in the warm sun throughout the day, making it crucial to position it in a spot that isn't shadowed by taller plants or structures.
TemperatureRock Rose prefers a warm climate and can typically withstand temperatures down to about 10 degrees Fahrenheit, but should be protected from extreme cold. This plant thrives best in temperatures ranging from 60 to 80 degrees Fahrenheit. Prolonged exposure to temperatures below 10 degrees Fahrenheit may damage or kill the plant.
PruningPruning the Rock Rose is important for maintaining a compact shape and encouraging vigorous flowering. It should be pruned in early spring to remove any dead or damaged wood and to shape the plant. Also, after blooming, it's beneficial to lightly prune to deadhead spent flowers and encourage a second bloom. Pruning can be done annually or as needed to keep the plant looking tidy.

Life cycleThe life cycle of the Helianthemum 'Henfield Brilliant', commonly known as the Rock Rose, begins with seed germination, occurring in spring under favorable conditions of warmth and moisture. Seedlings establish a root system and develop a rosette of leaves at the soil level. As they mature, stems elongate and foliage expands, with the plants forming a woody base characteristic of shrubby perennials. Flowering typically happens in late spring to early summer, producing vibrant orange blooms that attract pollinators and may lead to the formation of seed capsules if fertilization occurs. After the flowering stage, the plant may enter a period of dormancy, especially in hot summer climates, to conserve energy. With the arrival of cooler temperatures or the onset of the next growing season, the Rock Rose can resume growth, continuing its perennial cycle.
PropogationPropogation time
Spring-Early Summer
Propogation: The Helianthemum 'Henfield Brilliant', commonly known as the rock rose, is typically propagated during late winter to spring before new growth begins. The most popular method of propagation for rock rose is through semi-hardwood cuttings. To propagate rock rose cuttings, one should select a healthy, non-flowering stem and cut a segment around 4 to 6 inches (10 to 15 centimeters) long. Strip the lower leaves and dip the cutting end in rooting hormone powder to encourage root growth. The cutting should then be planted in a mix of half peat and half perlite or sand, ensuring that the leafless part of the stem is beneath the soil. The pot should be kept in a warm, well-lit area but out of direct sunlight, with the soil kept moist but not waterlogged. Roots typically develop within a few weeks, after which the new rock rose plants can be gradually acclimatized to outdoor conditions before transplanting.
