Mock Orange-Philidelphus Virginal Won't Bloom!
I have a Philidelphus Virginal mock orange. It gets morning sun and filtered shade in the afternoon. It is in a Western exposure, shaded by trees in the afternoon. I bought it from a local nursery. It's a really healthy plant, and it gets loads of new growth every season, but NO BLOOMS. I know it's not too young, because it was in bloom when I bought it! It's been in the ground for three years. It's about 5 feet tall and 4 feet wide. We have sandy soil, which I'm amending regularly with organic matter, trying to get it to a sandy loam.
I'm getting really frustrated, because I bought it for its wonderful fragrance!
Any ideas why it won't bloom? By the way, in a search of the Garden Web, I found another person who had a Philidelphus Virginal planted in a western exposure, and hers never bloomed either. Is it a problem with Virginal, maybe? Virginal and western exposures? Something else?
I'm open to suggestions... :) Thanks!
