Rock garden plants – our 6 favorites make the rocky landscape colorful

The rock garden is nothing new in garden art. More than two centuries have passed since the first rocky landscape was laid out in London’s Chelsea Physic Garden in 1773, but the popularity of this particular garden design continues to grow. Modern man is more and more attracted by the sturdiness of stones and the richness of color of certain rock garden plants. But what speaks to him most is the full harmony and serenity in the rock garden.
The rocky landscape in your outdoor space must be a lifelike imitation of the mountainous landscape and bring a little bit of it into your garden. Since robust and drought-resistant plants thrive particularly well in nature, they also fit into the rock garden. Among these species, however, there are some that appear as spots of color between the stones. They introduce lots of color and cheerfulness into a rocky garden design. Today we want to draw our attention to such rock garden plants and present our 6 favorites from their list.
Evergreen cacti are a welcome addition to any rock garden
The most creative part of designing a rock garden is its planting. Here you can give free rein to your ingenuity and express your skill in selecting and arranging suitable plant species. Our tip is: choose warmth-loving, hardy and easy-care plants. In the spaces between the stones, evergreen plants thrive, which determine the basic green color throughout the rock garden. This dominant color can be perfectly combined with the gray of the weathered rock to create a unique sight. Thick-leaved cacti and other succulents, which should not be missing in any rocky landscape, show a saturated green. For example, the houseleek can thrive anywhere and in principle requires almost no care.
The thick fleshy leaves of the various Sedum species store water and can easily withstand the drought

These succulent plants store water in their leaves and can withstand long periods of drought. That’s why they fit in every rock garden. But now let’s see which plants grow well between rocks and gravel and add a lot of color to this garden landscape. In the following, we present undemanding garden plants, which, however, bring their flowers to the fore in dry soil.
