HYSSOPUS OFFICINALIS BLUE
Plump spikes of bright blue flowers appear on this popular old bushy plant which doubles as both a minty herb and a lovely garden flower, and is especially loved by bees. If cut back hard each spring will make a superb specimen for many years.
For best results, sow immediately onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. We sow most seeds in an unheated greenhouse and wait for natural germination, as many seeds have built-in dormancy mechanisms, often waiting for natural spring germination, hence giving them a full season of growth.
