Caring for a Teucrium fruticans?

Hi, this is pruning group 7, which means giving the plant a hard prune to about 2 or 3 buds from the base each year in early spring, then add well rotted manure and mulch to compensate for the loss of vigorous wood, they should be grown in well drained, neutral to alkaline soil, in full sun, and in frost prone areas, in a sheltered border, or against a warm sunny wall, as they're only frost hardy.
As this only grows to 2 or 3 ft high, with a spread of 12 ft, I'm finding it hard to visualise as a topiary shrub, Derek.

Thanks for the advice Derekm.
