My Mary planted a little shrub in the garden last year, its evergreen, but its got yellow leaves, she said its
its a Mexican Orange Blossom, but I think shes daydreaming again, I mean to say, would a thing from Mexico grow in the frosts of Shropshire?
Its known as a mexican orange blossom but its correct name is Choisya ternata. Mexican orange is hardy to 10°F (-12°C). You can find more about it here.
The Mexican Orange Blossom, (choisia ternata) is very hardy and is grown as far north as Scandinavia, so Mary is right, again. Mine has just been touched by frost, as is normal, this is no problem, the damaged foliage gets overgrown or if you wish just remove the leaves. After flowering cut 12-15” off stems and the plant will flower again. Both foliage and flowers are scented.
