I have exactly the same problem. Bought a plant in the Springtime. Lots of foliage (reaching at least 6 feet) but no sign of any flowers

they may yet flower, but if by everlasting sweetpea you mean the perennial ones, such as Lathyrus latifolius, these prefer a shadier spot, so if you have them in full sun, they won't like that too much.
