They bloom lightly all spring and summer. And on my side fence, is its close relative trachelospermum jasminum with a small pinwheel blossom similar to its creamy cousin's, except white. It blooms once in the season, in late Florida spring. Again, a wonderful fragrance. Both of them bring to mind spicyness, mixed with floral.
People always ask what the delightful white flowered vine is.
The blooms are like snowflakes scatterd over the deep green leaves. It can be trimmed right after bloom and keeps an orderly appearance. They get fed in my yard when I remember to, and are doing well. A couple of times a year would be good. They are sometimes called Confederate Jasmine.
