The 'Supreme' rock rose is a low-maintenance plant that you will receive from us as a pre-grown seedling, ready for immediate planting. Choosing the right location is absolutely crucial for successful cultivation. This plant thrives best in direct sun and a hot, well-warmed spot. The soil should be nutrient-poor, light, sandy, and above all, well-draining so that excess moisture does not accumulate at the roots. Plant the seedlings in beds, rock gardens, or gravel areas 30 to 40 centimeters apart, which corresponds to roughly 9 to 12 plants per square meter. This spacing ensures enough room for the plant to grow in width while creating a beautifully uniform cover. If you do not have a garden, the rock rose is very easy to grow in pots or window boxes on a balcony. In such a case, do not forget to add a thick drainage layer of gravel or expanded clay at the bottom of the pot to prevent root rot, and use a substrate with a high sand content.
Once the seedling is well-established, it becomes an excellent drought-tolerant semi-shrub that requires almost no supplemental watering. You only need to monitor moisture for plants grown in containers, as the substrate dries out faster there. However, watering should still be very moderate and only after the soil has dried out completely. In terms of nutrition, the rock rose is completely self-sufficient, and fertilizing is not necessary—or even desirable. In soil that is too humic and nutrient-rich, it would form long, leggy stems and bloom less. This plant will save you a lot of time, and you will also appreciate its excellent durability. It does not suffer from any common diseases and is avoided by garden pests, making it an ideal choice for complete beginners.
Proper pruning is important to maintain a compact shape and rich flowering in the following years. The rock rose blooms profusely with small cherry-red flowers from May to July. These edible flowers also intensely attract bees and other pollinators. Once the plant finishes blooming at the end of the summer, we recommend slightly shortening its stems by about one-third. This pruning encourages the semi-shrub to thicken and prevents it from becoming bare at the bottom. During the winter, the plant retains its dark green leaves and creates a beautiful winter effect, so the bed will not remain empty. The rock rose is highly frost-hardy and reliably handles temperatures down to -23 °C. It will survive the winter in our conditions without problems; it is only important that it does not stand in waterlogged soil, which could damage the roots during frosts.
The information given is based on our experience, please use it as a guide only. Times may vary depending on the season, climate, location, sowing and transplanting dates and possibly also the conditions in the greenhouse/greenhouse. We always recommend testing how the plant performs in your conditions. Please do not take this as a guarantee.
