A so-called Green Rose
The Berlin papers recently brought us an indication of the existence of a green-blooming rose bush, which is owned by a local horticulturist and the writer soon received an invitation from the owner, the factory owner Mr. Mosgan, to view this curiosity. He found a rose plant in a container (a Bourbon-Rose as he was told), whose bloom and buds, however, were a cluster of green leaves. On closer view, it was evident, as the writer had already surmised, that these leaves were not real petals, but modified sepals, which occasionally occurs with various plants, especially with roses, i.e. nothing but a deformity where the formation of the bloom is interrupted and remains at the stage of leaf formation. In the present case, however, the deformity has reached such perfection, that it looks similar to a real bloom. Also, it is not just a single bloom which shows this abnormity, but all flowers of the bush have the same form, and the still underdeveloped buds indicate that they will also become such. The calyx is quite normal, the tube or Hypanthium is fully developed, of almost globular form, and in its youth at least, the flower stalk is covered with glands. The edge of the calyx consists of five lanceolate, deepend cuts, with some glandulous saw-tooths, which have at the tip a leaflike appendage of lanceolate form, which is sharply serrated at the edges. This calyx includes a dense rosette of green leaves, which all have the form and structure of the calyx appendages; there is no trace of the flower organs, i.e. petals, stamens and pistils. It seems that branches want to develop from the centre of this leaf rosette, as some....are connected by a common stalk, which is howver yet too small to define it as a new cane. as mentioned, the whole phenomenon is probably nothing more than a regression in vegetation, probably due to too rich nourishment, through which the food juice is led more to the outer parts which develop preferably, while the inner or nobler parts remain underdeveloped. The further development of vegetation will confirm this, if new canes are produced bye and bye out of the alleged blooms, a type of proliferation will happen. We could not make a through cut yet, maybe we will be allowed to do so later. It is curious that this phemonen has been quite constant up to now, as can be seen from the following declaration of the owner. He states: "This curious rose has been produced in France without any culture as a seedling, from which I have taken eyes and grafted them on a green rose standard. This now has produced several buds and blooms just like those of the mother plant, and the change in climate and soil has not made any modification of the form and colour." - But although this anomaly has so far proven to be constant, this shrub will still in time revert to its normal state, the sooner the culture is changed and the nourishment is modified; yes, perhaps this alteration would occur soon if the bush is planted in the garden. The owner however wants to cultivate it in the same manner, in order to see what will happen to it. We reserve therefore our right to make future communications on this. This preliminary indication is only to correct the mistaken opinion of rose lovers that there are really green roses.
