All catmints are loved by bees, but none more so perhaps, than Nepeta ‘Six Hills Giantâ€™ â€“ much wider than it is high, and at (3′x2′) not much of a giant at all. Bumblebees, honey bees and solitary bees love this plant because of its profusion of small nectar rich flowers accessible to short and long tongues and on a warm summerâ€™s day it is alive with rapidly foraging bees. Bumblebees visit as soon as the morning warms up and are the last to leave in the evening.
Flowering for many weeks from late June onwards, it will produce a second flush of flowers if cut back when first flush has faded. Catmints are members of the Lamiaceae family which includes agastache, hyssop, white dead nettle, marjoram, stachys, salvia, thyme - all of which are enormously attractive to bumblebees, and the closely related calamintha is particularly loved by the ginger Carder Bumblebee (Bombus pascuorum).
