Seedfork said:if he mentioned anything about the foliage?
Stout did not indicate very much, but this is what he wrote "The new leaves of ramets of Flore Pleno appear somewhat earlier in spring than do the leaves of Kwanso and they are more bluish green in color."
Ramets are fans.
In another article Stout wrote, "The propagation of these two daylilies is solely by vegetative means. It can not be otherwise, for the pistils of the flowers are entirely impotent." and "The writer has obtained entirely green-leaved plants under both names Kwanso and Flore-Pleno from various nurserymen and from various botanical gardens. These have been grown side by side for comparison and study. There seems to be no difference in the color of the flowers and the various aspects of the habit of growth. Some plants, however, have all flowers very double, while other plants have semi-double flowers, with also many inter-grades; various grades of doubleness may be found on the same plant."
Lastly he wrote (
by clon he means clones), "It is generally considered that the clon of the Daylily Flore Pleno introduced by Veitch & Son is less double than the Daylily Kwanso. It is to be noted, however, that these conditions are exactly reversed in the first illustrations of the two. The plate of von Siebold's plant published in 1866 (Gartenflora, pl. 500) shows a semi-double flower, while that of Veitch's plant (The Floral Magazine I: pl. 13) shows a flower much more double."
Stout would have examined the two plants beginning in the 1920s about 60 years after they were introduced into cultivation.
