Cultivation Details

HabitEvergreen Perennial
Growth—

Prefers a humus-rich, moisture retentive soil and partial shade, though it can also succeed in full sun[2, 3, 4, 5]. Does well in marshy soil and in the spring meadow[6]. Grows well in dry shade[7, 8] and is fairly drought tolerant once established, though it shows distress in severe drought[8]. Plants do not always ripen their seeds. They spread freely by runners, however, and can soon form an extensive patch in suitable conditions[9]. Plants spread quite aggressively by stolons and can become a problem in gardens if poorly sited - they are particularly aggressive in lawns, for example[5]. A number of forms have been selected for their ornamental value, several of them are variegated and these are used especially as ground cover plants for dry shade[7]. A purple-leafed form, 'Atropurpurea' does well in full sun so long as the soil is not dry[10]. If required, plants can be mown on a high setting after flowering in order to remove the old spikes[5]. A good bee and butterfly plant[6].

Propagation

Seed - sow spring or autumn in a cold frame. The seed usually germinates in 3 - 4 weeks at 10°c[11], though it can be erratic[12]. Prick out the seedlings when they are large enough to handle and plant them out in the summer[PFAF]. Division of runners at almost any time of year. Very easy, the divisions can be planted straight out into their permanent positions if required.
