You can count on Geranium 'Azure Rush(R)' for a tidy, mounded cranesbill that keeps your garden looking fresh for months. It forms deeply cut green foliage and sends up abundant blue-purple flowers over a long bloom season, making it an easy choice for borders, cottage gardens, and mixed plantings where you want steady color without constant fuss.
At maturity, expect a compact clump about 18-20 inches tall with a spreading habit that can reach roughly 24-28 inches wide. Plant it where it has room to fill in naturally, or use it to knit together the front of a bed with other perennials and small shrubs. It also performs well in containers when given consistent moisture.
For best results, grow it in full sun to part shade. In hotter areas, afternoon shade helps the foliage stay attractive and keeps flowering strong. Provide well-drained soil enriched with compost, and water regularly during the first season to establish a deep root system. After that, water during extended dry spells to keep growth and bloom steady.
Maintenance is simple: remove spent flower stems as desired and shear lightly after a flush of bloom to encourage fresh foliage and continued flowering. This cranesbill is known for attracting butterflies and is often noted for deer resistance. Cut back after frost and watch it re-emerge vigorously in spring.
