"Pest-Proof, Fool-Proof, All-Purpose Roses". Some Outstanding Species Described By C. R. McGinnes
I will list briefly the characteristics of some of the outstanding sorts among the more than two hundred which we have in our garden at this time. Starting with the earliest ones, the yellow group, we have R. Ecae, then, about three days later, R. primula. Both roses are very beautiful shrubs about six feet high. There seem to be two different roses under the name of R. Ecae, one discovered by Aitcheson in Afghanistan, the other named by Dr. Rehder. The latter has recently been changed to R. primula, although Beckwith maintains that it is a variety of R. xanthina known as Kokanica. The flowers of the former are deeper in shade than the latter, both being a light yellow; the foliage is identical except that R. primula has an odd fragrance, something like Scotch whiskey

Rosa ecae Aitch. A very spiny, shrubby rose, flowering in early summer, with an abundance of small, deep-yellow flowers. Recommended for hybridization to create perfectly hardy yellow roses. (Adapted from a note of Frank N. Meyer, dated July 10, 1910).

[After R. Hugonis] the next species to flower here, R. Ecae, is a very spiny shrub with small leaves and pale yellow flowers not more than an inch in diameter. It is a native of Afghanistan, where it is common on dry mountain ridges, and of Samarkand and although of some botanical interest it has little to recommend it as a garden plant in this region. In 1820 an English botanist found in a collection of Chinese drawings in London the picture of a double yellow Rose to which he gave the name of R. xanthina, and many years later the single-flowered form of this Rose was found growing wild in Mongolia by the French missionary David. English botanists have usually confused the Chinese Rose with R. ecae and it apparently had not been cultivated in the United States or Europe until 1908 when the Arboretum received from the Department of Agriculture seeds of this Rose gathered in China by its collector, Mr. F.N. Meyer. Both the single and double-flowered forms were raised from this seed and have flowered in the Arboretum this year. The flowers are larger than those of R. Ecae and bright clear yellow. These Roses appear to be perfectly at home in the Arboretum, but it is too soon to speak of their value in North American gardens. The single and the double-flowered varieties are much cultivated in the gardens of Peking.
