This species grow from woody short stems, usually several inches tall and bloom in late fall - a few weeks before some asters and hardy chrysanthemums blooms. The height of the plants usually reach from two to three feet before dying back to the wooden stem in winter. Have very large leaves for a clematis and will grows in woodland shade. Oddly enough it is not sold in the plant trade often even thought it is easy to plant and selfsown.

Tube Clematis or Hyacinth-flower Clematis is a nonclimbing form of clematis yet truly perennial with toothed foliage and skyblue,tubular, star shaped flowers in summer. I grow C. heracleifolia from seeds that I 've traded here on DG. I've sown the seeds at 20C (68F). If theres no germination in 3-4 wks, move the seeds to -4 to +4C (24-39F) for 2-4 wks. You could even try winter sowing. The seedlings will flower in their second year. During my house removal it has survived in a small pot outside in temps down to -15oC. So it's a quite little tough plant with very pretty blue flowers...I find them rather big for the plants size.

Tube Clematis is an very interesting plant, its flower varies very much in the wild area in China,the size,color,shape and fragrance is different among different plants, I notice it four 4 years, it is surely a valuable gene resource for breeding.
