How to grow

Cultivation Grow in moist, fertile soil in full sun. Flowering stops in dry weather unless watered freely. Pinch out growing tips to produce bushy plants, and instead of deadheading, trim off flowering shoots when initial flowering is finished to promote more flowers

Propagation Take softwood cuttings from the ends of non-flowering shoots in late summer and overwinter plants in frost-free conditions or take softwood cuttings in spring
