Alpine Plants for Difficult Sites: Tough Beauty for Rock Gardens

Alpine plants—natives of high mountains (New Zealand, Northern Hemisphere)—are built for extremes: rapid temperature swings, screaming winds, lean soil, drought. They turn impossible garden spots into showcases.

Why They Work

• Low, cushion/mat habit (wind-proof, heat-trapping)
• Deep, anchoring roots
• Wiry stems, tough leaves
• Moisture-loving but drought-tolerant once established
• Pollinated by flies, beetles, moths (not bees—reliable in cold)

Low-Care Once Established

Ground-hugging form = self-mulching. Small size = no pruning. Deep roots = self-watering. Plant them; mostly leave them alone.

Flowering Stars

• Mountain daisies, buttercups, alpine phacelia, terrestrial orchids (spring/summer)
• Alpine eyebright (Euphrasia officinalis) – July–Sept color
• Edelweiss, hebes, vegetable sheep (Raoulia rubra – sponge-like cushion)

Reliable Selections for Rock Gardens

Coprosmas, turpentine shrub, mountain toatoa, sundew, tussock grasses, campanula, dianthus, alpine aster, Japanese poppy.

Design Tip

Cluster in drifts among rocks. Let them spill into crevices. Mimic the scree slopes they call home. The result: a garden that thrives where nothing else will.
