Cosmos Bipinnatus Seashells Mix
Cosmos Bipinnatus Seashells Mix. An Heirloom variety from the 1800’s producing an exquisite display of tubular-petalled blooms somewhat similar to a sea shell in lovely pastel colours of white, pink, rose and crimson on tall and busy plants with delightful lacy fern-like foliage.
