Dense clusters of saucer shaped, heavily veined rich violet flowers appear among deeply divided, mid-green leaves in one burst in midsummer.

This vigorous plant quickly forms hummocks of attractive, deeply divided foliage that colours beautifully in autumn. It's an effective and low maintenance groundcover plant. Although Geranium × magnificum 'Rosemoor' will take some shade, it flowers best in a sunny site.

How to care for Geranium × magnificum Rosemoor:

Incorporate plenty of organic matter when planting and water well in dry weather, especially newly established plants. Apply a generous 5-7cm (2-3in) mulch of well-rotted manure or garden compost around the plant to help seal in moisture, feed the soil, and reduce the need for weeding.

Deadhead spent flowers regularly to encourage continuous blooming. If the plant becomes too leggy or untidy later in the season, trim lightly to encourage fresh growth and more flowers.

During the first growing season, regular watering is crucial to establish deep roots, but once established, hardy geraniums show commendable drought tolerance. A feed of balanced, slow-release fertiliser in spring will support its prolific blooming.

One of the many virtues of this perennial geranium is its resistance to pests and diseases, making it a low-maintenance choice for gardeners. To encourage a second flush of blooms, trim the plant back by one-third in midsummer (aka ‘The Chelsea Chop’).

At the end of the growing season, cut it back to ground level in late autumn or early spring. Every 3-4 years, consider dividing the plant in spring to maintain its vigour.
