How about some alpine plants are perfect for rock gardens. A few I have grown iDianthus (Pink), Phlox subulata (Creeping Phlox), Aubrietia (Rock Cress), Euphorbia (Spurge), Stachys byzantina (Lamb's Ears), and Helianthemum (Rock Rose) create an eye-catching display. The garden explodes in a firework of colors for months and requires moderate care. Lewistas pink collection is my absolute favorite.
Look them up and pick what you like and leave the rest. All need fast draining soil and part to full sun 6 -7 hours a day.
Happy planting..
