Despite a name that suggests a love child of the ’60s, River Indigo (Indigofera Frutescens) is a most practical small tree and a forest ‘starter’ that grows like lightening. I planted one to replace an exotic and thought it was going to take years to rise to the challenge. Eight months later it has almost tripled in size. It also is awash with the most beautiful dark pink to light pink flowers and has pretty much been flowering all spring and summer. It’s a lovely sight to behold. It likes a bit of shade, and apparently needs to be pruned after flowering has ended. I love my River Indigo, and it’s easy to forgive her her slightly dodgy name.
