Golden Katrina' is a compact, upright, bushy, evergreen shrub bearing broadly elliptic, grey-green leaves with pale yellow margins and dense racemes of purple flowers in summer.
Although the shrub doesn’t need much in the way of fertilizer, you can apply some once a year in late winter or early spring prior to new growth.
Deadheading the spent blooms can be done to help promote additional flowering. You can also trim hebe plants back about halfway after flowering to promote bushier growth.
