Mint Shrub. Where has this little sub-shrub been all of my life?! A relative of Buddleia, it can be treated similarly by pruning it back heavily in late winter. Normally it puts on a display of its fuzzy pink spires in the fall, but here in the Deep South its starts to grow so early, that we are usually treated with a flush of flowers in late March through April. If this happens, I would recommend pruning back the spent flower heads to induce a good flush of new growth for the fall when it normally flowers for the rest of mankind. Grow on just average, well drained garden soil. Our next availability of this selection will be June, 2021.
