Variable Clusters of Hybrid Larkspur

These specimens of hybrid larkspur are selected as suggesting the considerable range of variation in the make-up of the clusters of blossoms. Note the very striking contrast between the cluster at the left and that at the right, the latter being the result of a long series of experiments in careful selective breeding. Compare this picture with earlier ones of this series, to suggest the full range of variation in form and color among the selected hybrid larkspur.
