Just when you need a lift, Acacia dealbata, or mimosa, gives it to you, with masses of heavily-scented yellow flowers.

What is there to love about the mimosa tree? Its masses of tiny yellow pom-pom flowers? Or their scent, which carries so far and stuns you on a cold early spring morning? Or the brightness, when so much else is grey? Or the filigree feathery foliage, with its tight ferny fingers?

I’m not sure what I love most about it, but one thing’s for sure, our new garden is missing a tree, and this one’s the tree that we want.

You can prune the acacia in mid-spring once the heavy frosts are gone, and they do benefit from a bit of attention in the early years to encourage a good tree shape. And as this can grow to 30m (over a rather long period, it must be said), then they might need a prune in urban areas to stop them taking over too much too. You’ll also need to be confident that you can give this tree a sheltered, warm spot so that it survives. I’ve already lost one acacia in my life to a particularly snowy winter, so try not to get too attached.
