This is an evergreen shrub funnily enough from the Canary Islands with small grey-green leaves with a Pennyroyal scent so plant it near where you walk so as to brush past it. It is however for its masses of fluffy grey flowers produced almost throughout the summer and autumn that you would chiefly grow it. It should grow to about 2metres and needs to be pruned really hard each winter to stop it becoming leggy. The flowering stems are fantastic for floral art and last for ages.
It requires a sunny well drained site and is fairly drought and cold tolerant so what more could you want? I have plants in 6″ pots in bloom and selling for $18.50.
