Agastache – Rose Mint
Agastache are often referred to as Hyssop. With fragrant aromatic leaves this natural looking plant will help feed and are loved by butterflies and other pollinating insects alike – they seem irresistible to them. The flowers are very pretty and are produced in abundance, from late spring to summer.We grow 5 varieties(!) and are very relieved that they are now looked upon as a worthwhile perennial. As they are a member of the mint family they do not like the wet and prefer a dry patch. We bring our stock in to keep dry rather then warm – they behave much better when planted in the ground.
Sow indoors. Sow onto moist well-drained seed compost. Press seeds lightly into the soil but do not cover. Light is needed for germination. Propagate +20°C. Germination takes up to 14 days. Water only from the base. Once germination begins admit air to prevent damping off. Once seedlings are large enough to handle transplant to 8cm pots and grow on in cooler conditions. Acclimatise and plant out after danger of frost has passed with 45cm spacing. OR Can be sown directly in spring into free drainng well prepared soil.
By the way – slugs don’t like the taste of any Agastache!
