'Else Poulsen, Improved'. Hybrid polyantha. Dwarf. A seedling of the above ['Else Poulsen'] and is so similar in blooms, colour, shape and growth that it is rightly entitled to bear the name. It is, however, slightly less prolific and the flower clusters are somewhat smaller, but these are the only differences. Should be planted in somewhat closer groupings (mildew-proof).
