THIS double-flowered dwarf Dahlia is certainly the most attractive of the genus. It is supposed to be
only a variety of the D. pinnata, but the variation is almost powerful enough to constitute a species;
as, besides the difference in its flowers, we have never found it arrive to more than half the height
of the pinnata, although we have seen it every autumn for four years in luxuriant bloom. At present
it is a scarce plant, and appears to be not quite so hardy as the taller species, nor so easily increased.
Our figure was made from a plant in the collection of the Right Hon. Lady Holland, at Holland
House, Kensington.
