Answer: The natural growth habit of scabiosa is to produce wiry stems, topped with pincushion-like flowers. The leaves are generally oblong and coarsly toothed, with a slightly downward curve. Sounds as though you've remedied the rootbound condition and the next step is cutting the plants back to encourage healthy new growth. Deadhead frequently by removing spent flowers along with some stem, and your plants will become bushier.
