Leonurus cardiaca Motherwort
40 seeds per packet.
Native to Central Asia and south-eastern Europe, this member of the Mint family has a long history of medicinal use. Its leaves have three distinctive lobes with pointed tips and diminish in both length and lobe size in the upper parts of the plant. Whorls of small, sessile, pink-lilac flowers with tubular, two-lipped corollas bloom from July to September in rosettes nestled in the leaf axils. Leave the seeds heads for winter interest. Height 1 metre. Part sun in moisture retentive soil.
Sow from March to June. Cover seed thinly, press in gently and keep top of compost from drying out. Keep pot warm at 15 to 20°C until germination, then move to somewhere cooler.
Carefully prick out seedlings when they have developed true leaves and are large enough to transplant to individual pots to grow on.
