Description
f you love that fresh, modern look in the garden — soft silver foliage, clean structure, and year-round interest — Eucalyptus gunnii is a standout. Its rounded juvenile leaves have a beautiful blue-silver colour and a crisp, aromatic scent, making it a favourite for contemporary planting, large pots, and for cutting fresh foliage for the house.
It can be grown as a small tree, or kept compact with regular pruning (which also encourages lots of that lovely juvenile leaf). Give it sun, space, and free-draining soil, and it becomes a striking, architectural feature that lifts everything around it.

Caragh Garden Notebook
Eucalyptus has a way of making a garden feel instantly fresher — that silver-blue colour, the movement in the breeze, the clean shape against green planting.
Eucalyptus gunnii is one of the most useful: it can be a beautiful small tree if you let it grow, or you can keep it compact and leafy with a regular prune (and that’s when you get the best cut foliage too). It’s brilliant paired with grasses, salvias, lavender and deep greens — anything that lets that silver really sing.
Caragh tip: Decide early how you want to grow it — tree form or kept compact. If you’re pruning for foliage, do it in late winter/early spring so it comes back strongly for the season.
