Verbena hastata 'Blue Spires'

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. Zones: 3 to 8 Family: Verbenaceae Type: Perennial Height: 24 to 72 in. Spread: 12 to 30 in. Exposure: Full Sun Soil Conditions: Moist, average Bloom Time: June to September Bloom Color: dark blue
