Rock plants

What are the best-known and most popular rock plants?

When we look at the most popular rock plants, we often see species that excel in color and form. The well-known Aubrieta forms a spectacular purple or blue carpet over stones and walls in the spring. The various species of Sedum are also hugely popular rock plants due to their decorative fleshy leaves and extreme resilience. In addition, the Campanula is a classic that weaves beautifully through rock crevices with its fragile blue flowers. These rock plants are so popular because, with their compact growth habit and vibrant bloom, they immediately add character to the stonier parts of the garden.

The benefits of rock plants?

The greatest benefit of rock plants is their enormous resilience. These plants are naturally accustomed to harsh conditions, such as intense sun and little water. A rock plant therefore has very modest water requirements and can easily take a beating. In addition, many rock plants are evergreen, ensuring your rock garden or border maintains a neat, green appearance even in winter. Because they stay low to the ground and often form dense cushions, they also work excellently as natural weed suppressors. For those who love a garden that requires little time but offers plenty of color, these hardy plants are the perfect solution.

What to look for when buying rock plants?

When selecting new rock plants, it is important to consider the location. Pay specific attention to the following points:

What types of rock plants are there?

There is a wide variety of rock plants, roughly divided into flowering cushion plants and succulents. Cushion plants, such as Soapwort or Candytuft (Iberis), form dense mats that become completely covered with flowers. On the other hand, you have succulent-like rock plants, such as Houseleek (Sempervivum), which stand out primarily for their beautiful geometric rosettes. Dwarf varieties of perennials and small ornamental grasses can also serve excellently as rock plants. For every style, from a sleek modern patio garden with planters to a wilder, natural rock garden, a suitable species can be found that softens the stony elements.

How and where do I place my rock plants?

The ideal spot for a rock plant is a sun-drenched elevation, a rock garden, or in the crevices of a dry stone wall. Good drainage is essential when planting; mix the garden soil with plenty of coarse sand or gravel. Dig a hole just large enough for the root ball and press the rock plant firmly between the stones. Do you have a slope? Then position the plants so that excess rainwater drains away easily. You can also perfectly place rock plants in pots or troughs on the terrace, as long as there are holes in the bottom of the pot for drainage. Finishing with a layer of split or gravel around the plant prevents the lower leaves from rotting.

How do I care for my rock plants?

The care of rock plants is minimal. After flowering, you can lightly prune many varieties to maintain the compact shape and encourage a possible second bloom. Only water during extremely dry periods; a rock plant is a champion at surviving with little moisture. Fertilizing is only necessary very moderately; too much nutrition often results in weak growth and fewer flowers. In spring, it is sufficient to sprinkle some organic fertilizer around the rock plants. Occasionally remove windblown leaves or weeds from between the cushions to keep the plants airy and healthy. This way, you will enjoy these hardy mountain dwellers for years to come.

Frequently asked questions about rock plants

Can rock plants also be planted in a regular border?

Yes, absolutely! A rock plant does excellently at the edge of a border, provided the soil there is not too heavy and wet. They form beautiful, natural edges along paths and ensure a smooth transition from paving to planting.

Are all rock plants winter hardy?

Most rock plants that we offer are very winter hardy. Because they come from mountainous regions, they are accustomed to the cold. However, winter wetness is often a bigger problem than the frost itself. Good drainage is therefore the best protection for your rock plant during the winter months.

How fast do rock plants grow?

The growth rate varies by species. Some rock plants, such as Aubrieta, can form substantial cushions in a few seasons. Other species, such as Houseleek, grow more slowly and propagate by producing small 'offspring' around the mother plant. With these plants, patience is always rewarded with dense growth.

Do rock plants need special soil?

A rock plant loves poor, well-draining soil. Preferably use special rock garden soil or mix your own potting soil with plenty of coarse sand, gravel, or perlite. This mimics the plant's natural, stony habitat and prevents root rot.
