12 Rockery Plants To Grow On Rock Gardens

Last Updated on May 20, 2022 by Real Men Sow

You can create a rock garden that displays small or alpine plants. You only need a few large stones or stones, some free-draining soil, and a mixture of rockery plants. Both sun- and shade-loving species can be grown. The sun-loving plants may be planted in the foreground, while the shade-loving plants can be placed in the shade by large rocks.

What Are Rockery Plants?

Alpine plants are found in mountainous areas. They are often cold and dry, so they don’t grow tall. There are small plants that can be grown in rock gardens, but they are not always alpine. They thrive in warmer climates. A rock garden display that includes both alpine and non alpine plants can be attractive if it is well-planned.

Thyme

There are many types of thyme, and they come in a variety of colors. The leaves can be dark green or golden or variegated. They are ideal for rock gardens because they have a spreading, low-growing habit. Plant in full sun in well-drained soil. (H x S: 20cm x 40cm)

Saxifrage

Houseleeks

Sempervivums, also known as hens and chicks, are tough, succulent plants that are native to mountainous outcrops. They look great in rock gardens, especially when paired with low-evergreen plants like sedums. They will thrive in full sun in well-drained soil. (H x S: 30cm x 40cm)
