I don’t think there is any gardener that would not want this plant of true blue flower and dark green foliage.
Lithodora ‘Grace Ward’
It appeared to survive in my garden for a few years. I am not sure it disappeared because of over-crowding and neglect or because of the weather, or the soil condition. It is worth another try if I can find one.
Lithodora diffusa ‘Heavenly Blue’
It survived two winter, and not sure it perished because of voles or weather condition. It is worth another try if I can find one.
