WaterRockrose 'Thrive' prefers a well-draining soil and should be watered deeply yet infrequently to encourage a strong root system. In the first growing season, water the plant about once a week with approximately 1-2 gallons, depending on soil and weather conditions, to establish it. Once established, the Rockrose is drought-tolerant and can typically survive with natural rainfall, though a monthly deep watering during prolonged dry spells can be beneficial. Always check the top few inches of soil for dryness before watering. Overwatering or poor drainage can lead to root rot, so ensure that the plant is not left in soggy soil.
LightRockrose 'Thrive' thrives in full sun conditions, needing at least six hours of direct sunlight per day to perform best. Plant it in a spot where it can receive unfiltered, direct light throughout the day. Dappled light or partial shade may cause the plant to grow less vigorously and produce fewer flowers.
TemperatureRockrose 'Thrive' can endure a wide range of temperatures but prefers a warm climate. It can tolerate minimum temperatures down to about 20 degrees Fahrenheit but may suffer damage if exposed to prolonged frosts. The ideal temperature range for Rockrose 'Thrive' is between 60 and 80 degrees Fahrenheit, where it can grow and flower optimally. Ensure it's protected or covered if a sudden cold snap is forecasted.
PruningRockrose 'Thrive' benefits from pruning to maintain its shape and promote vigorous growth. Prune the plant lightly after it blooms to remove spent flowers and encourage a second bloom. Pruning can be done annually or every other year, depending on the growth rate and desired size. The best time for pruning is in late spring or early summer, once the main flowering period has finished.
CleaningAs needed
SoilThe best soil mix for Rock Rose (Cistus × obtusifolius 'Thrive') is well-draining with a composition of loam, sand, and a bit of organic matter, ensuring good aeration and drainage.

Life cycleCistus × obtusifolius 'Thrive', commonly known as a Rockrose hybrid, begins its life cycle with seed germination, which requires well-drained soil and a sunny location. Once the seedling emerges, it enters a vegetative growth phase, developing a woody base and evergreen leaves. As the plant matures, it goes through a flowering stage, usually in late spring to early summer, where it produces showy, rose-like flowers that attract pollinators. Following pollination, the Rockrose forms seed capsules if the conditions allow for sexual reproduction, which then disperse to start the cycle anew. The plant also expands through vegetative means as it becomes larger each year, with a life span of several years. Seasonal conditions trigger periods of dormancy, particularly in colder regions, where the Rockrose may shed some leaves and reduce growth until favorable conditions return.
PropogationPropogation time
Spring-Early Summer
Propogation: The most popular method for propagating the Rock Rose 'Thrive' is through semi-hardwood cuttings. The ideal time to take these cuttings is during late summer when the new growth has begun to harden. To start, you would cut a 4 to 6 inch (about 10 to 15 cm) length of stem, making sure that it includes several leaves and at least one node. These cuttings should then be stripped of their lower leaves, dipped in rooting hormone, and inserted into a mixture of perlite and peat moss. The cuttings need to be kept moist and in a well-lit area, but out of direct sunlight until roots have developed, which usually takes several weeks. After rooting, they can be transplanted into individual pots and grown on until they are robust enough to plant outdoors.
