VERBENA HASTATA BLUE
This lovely, bone hardy, long flowering plant from Nova Scotia has many-branching candelabra type flower-heads, each spike of flowers slowly expanding as it ascends the stems, just like sparklers burning but in reverse. This is a valuable addition in that rarely seen true-blue colour. You may discover the occasional pink-coloured variant amongst the seedlings and these should be removed on flowering.
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.
