Q.Silver lace vine
My vine is growing very well in full sun … it doesnt bloom. It is in a sandy, black dirt mix, gets water, has healthy leaves and grows but no blooms

It does best in full-sun locations and is most vigorous in fertile, well-cared-for sites.
You could do a soil test, excess nitrogen can inhibit flowering. A boost of phosphorous in early spring can help with flower formation.
