Philadelphus coronarius
'Aureus'
Golden Mock Orange
Mike's
Opinion
"
This is a nice shrub if you like a bunch of fragrant flowers. The orangy-blossom fragrance is very fresh. This cultivar specifically I like because of its golden yellow leaves. I like that it adds contrast to a garden's colour scheme bringing yellow and white into the garden.
