It is a show-stopping perennial that brings massive, fragrant blooms to your landscape from late spring through early summer.

They are incredibly meaningful gifts, symbolizing prosperity and love, but they do require a bit of patience as they typically take three years to reach their full, glorious potential.

Most gardeners assume a small quart-sized plant is a minor addition to a landscape, but this Clematis is a true vertical powerhouse in waiting.

The red-purple blooms offer a dramatic visual impact that transforms standard trellises into living tapestries. You really only need to ensure it gets at least four hours of sun and fits within USDA zones 4 through 9 to see it reach its full 6-to-10-foot width.
