Nepeta curviflora (1.5lt)

Syrian catmint. This is a little grown and lovely form of catmint that makes a well mannered clump of silver backed green foliage from which in summer the stiff spikes of delicate violet blue flowers ascend. Like most Catmints it is very happy on poor soil in full sun with little moisture, and despite it native origins in the Middle East, it seems very hardy and happy here in the UK, so long as the soil is not waterlogged. On warm days the whole plant hums under the weight of pollinating insects. Height and spread to around 60-80cm x 40cm.
