Berberis varieties such as B. darwinii, B. ottawensis or Rose Glow (the last two are deciduous), Ceanothus, Deutzia, Escallonia, Forsythia, Hebe, Hypericum 'Hidcote', Ilex, Olearia, Osmanthus, Sambucus, Viburnum to name a few. All fine in alkaline soils.

Hello! My only concern, is that Aucuba does not like limey or alkaline soils, preferring a neutral to slightly acid soil, so it may start to show signs of sickness. You may be able to combat this by giving it a good dose of ericaceous feed or sequestered iron once in a while, but in the long term, you may be better off replanting it in a large pot (increase size over the years) with a mix of John Innes No.3 and ericaceous compost.

That's a new one on me, Avkg47 - as far as I know, and according to my info here, Aucuba tolerates a very wide range of soils and conditions.

Hello, bamboo ... Aucuba is definitely one of the neutral to slightly acid shrubs that I have come across, and will tolerate a wide range in that area, without the strong alkaline/lime soils, or the strong acid. They survive for a while but eventually the lime gets to them and they start to yellow off and die back.

I haven't had much luck growing Osmanthus in our alkaline soils here, either. Our soil is pretty extreme in alkalinity, though!

Evergreen Jasmine is stunning and produces loads of highly scented flowers throughout summer.
