Rock gardens are an interesting alternative to the classic, European garden concepts and can be attractively implemented with a little work and artistic ideas. The right rock garden plants, which do not have to hide from other plants with their variety of flowers, are important for this type of garden. The number of plant species ranges from perennial succulents to annual flowers, which make the heart smile with their colorful splendor.

40 species of annual and perennial rock garden plants
The rock garden plants are a world of their own. Because of their properties, they are well suited for a garden that does not consist exclusively of fresh grass, moist soil or vegetable beds. This type of garden radiates its very own charm and inspires with the design options that arise here. Whether it's a Japanese-inspired meditation garden, an alpine oasis for relaxation or a Mediterranean garden with a stream, the plants provide the special character.
Typical properties of plants and rock gardens are:
- resistant to drought
- come from either alpine or arid areas
- grow best on a gentle slope
- prefer south or south-west location
- Light requirement is usually high
- stones, gravel or gravel are required for the gardens
- some species are even quite thirsty

Another feature are the colors of the rock gardens, as these are often presented in darker shades that immediately catch the eye in the grey, stony surroundings. An advantage of the plants is the possibility to set them either in groups or solitary. Because the rocks can be placed either naturally or artistically, the location of each rock garden plant is important to the overall look. The individual species differ mainly in their life cycle, which you can include in the project depending on your personal taste. The list below for annuals and perennials will help here.
Annual rock garden plants
Even though many of the plants can withstand drought and warm temperatures, there are some specimens that are neither hardy nor persistent over several years. Annual rock garden plants will delight you for a period of time and will need to be replanted or seeded the following year. Compared to perennials, annual rock garden plants are clearly outnumbered in the local latitudes.
