In the introduction year, A.B. Stout described it as:
"
The general habit of this plant, an illustration of the flowers of which is shown on the cover,
resembles that typical for the erect type of H. multiflora, which is one of its parents,
but the plant is more robust and the flowers are larger and they have a flush of fulvous coloring.
The scapes are about 34 inches tall, slender, well branched and mostly extending above the leaves.
The foliage becomes brown, wiry, and fully dormant in autumn and the plant appears to be very hardy.
The open flower has a spread of about 3 1/2 inches; the coloring is chrome-orange with a delicate flush of reddish especially over the outer half of the petals.
The flowers are well open throughout the day until about dusk.
At New York this plant has bloomed with conspicuous profusion during late August and its period of bloom has continued into September.
