Potentilla

Potentilla (shrubby cinquefoil) is an exceptionally hardy, low-maintenance shrub perfect for Southwestern Ontario gardens. This drought-tolerant plant thrives in full sun and adapts to poor, rocky, or clay soils—even without regular fertilizing. It blooms continuously from June through the first frost in shades of yellow, white, pink, orange, and red. Plant in spring to allow roots to establish before winter. Space 3–6 feet apart for good air circulation. Water regularly during the first season; once mature, it needs water only during extreme heat or dry spells. Prune in late winter or early spring, and rejuvenate every 3–5 years by cutting back to about 1 foot to maintain a neat appearance and encourage fresh growth. Hardy to zone 2, potentilla resists deer browsing and requires minimal care—making it an ideal choice for gardeners seeking reliable, season-long color with minimal effort.
