NEPETA FAASSENII 'SIX HILLS GIANT'
This bushy, clump forming catmint is probably the best variety for edging and low borders, forming mounds of small, grey-green leaves with loose spikes of tubular, soft lavender-blue flowers. These open all summer long, persisting well until cut back by frost.
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.
