No flowers

My Choisya "Sundance" is growing well, however in it's 3rd year in my garden and still is quite shy to produce any flowers. All other plants (clematis, roses, trumpet flower, trachelospermum, peonies, poppies, campanulas) are flowering to their max, but not my Sundance.
Why is that?

Hi, Joanne,
Thought it doesn't flower as profusely as the straight species, I would expect yours to have blossoms by now. Is it in full sun? If not, that would explain it. If it is, perhaps give it a feed low in nitrogen, high in phosphorus - the nutrient responsible for promoting flowers (you can find this in any garden centre).
