Sorry Sold Out for 2023
30 seeds per packet.
Native to the Pyrenees, producing large, heart-shaped leaves and tall, purple stems, topped by umbels of long flowering, soft lilac flowers (which insects adore). Height 1.2 metres. Moist, well-drained soil in sun to light shade.
Can be sown from autumn to June. Cover seed thinly, press in gently and keep top of compost from drying out. Keep pot cool over winter. Keep warm at 15 to 20°C in spring 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.
