I planted a Philadelphus (I think it’s Virginal) about 3 years ago, in a sunny spot, neutral but good soil. It didn’t flower at all in year 1, last year I got a single flower, and this year there’s just a single cluster of five flowers on the whole shrub. It’s very healthy and growing vigorously, I pruned it lightly after the one flower finished last year. Can you give me any idea why it’s so reluctant to flower?

Philadelphus can take a few years to grow vigorously and then settle down to flowering. Do very little or no pruning until flwoering is established.
