Wild collected by the late Michael Wickenden as a Nepeta species but we suspect something else. Tall, branched spires of tiny bright blue flowers, 1.4m.
Brilliant little hummocks of deep green curled leaves will spread in time to form a low evergreen groundcover. Pretty spring flowers. Good soil in shade ideally. 15cm.
Rarely seen green leafed form of the famous "black grass" with beautiful milky white flowers in mid to late summer. Good evergreen groundcover, even in quite dry shade.
