Hi!
You are right. An herb rock garden is really pleasing to the eye and also useful, as you can enrich the kitchen with the herbs. But you can also combine herbs with other plants that, for example, have beautiful flowers, which makes the whole thing even more interesting.
The location where you want to create the rock garden seems perfect. Now you just have to get to work and you will see, it really isn’t that much effort. The soil should be a good mix of clay, sand, and compost. The mixing ratio should depend on the plants chosen.
Stones: Large natural stones are best, arranged irregularly according to your own imagination. The planting is done between the stones.
The following flowers are well suited:
[Herbstzeitlose], [Krokusse], [Märzenbecher], [Schneeglöckchen], [Wildtulpen] or [Blausternchen].
Best regards,
[Gartengestaltung] :)
