English Horticultural Notes.
REGELIO-CYCLUS IRISES. What have been termed "the finest novelties of the last ten years." were presented before the Royal Horticultural Society on May 17, by C. G. Van Tubergen, Jr., Zwanenberg Nurseries. Haarlem, Holland. These were hybrid irises in rare colors and of exquisitely graceful forms. The visitors were astounded, and everybody gazed upon the remarkably beautiful flowers with rapt admiration. The English horticultural press has illustrated and described the varieties, eight of which received certificates and awards, while the group, small though it was obtained a silver-gilt Flora medal the highest award given by the committee on that occasion. These things speak well for the merit of the newcomers. I shall not attempt separate descriptions of each of them; it may suffice to say that such colors as these were displayed Royal purple over gray; light gray or white ground, netted with bright violet-purple: magenta-purple veined with black, the same flower (Iphigenia) having falls of dark chocolate-brown with heavy brown veins over creamy buff edge. Others were dull coppery brown suffused with purple, light gold edges, and black veins; or primrose ground reticulated with mauve purple; and, lastly, rose-magenta on standards, and falls of coppery brown edged buff gray. These are surely remarkable combinations of colors In flowers. Mr. Tubergen says the hybrids grow vigorously in a light, warm, moist soil, and he has had them in hand for the past six or seven years. They are crosses between the oncocyclus (or cushion) and Regalia groups of the genus Iris, and the species chiefly employed have been I. Korolkowi, I. iberica, I. Iberica Van Houttei, and I. atropurpurea. The varieties receiving awards were: Antigone, Thalia, Isis, Iphigenia, Charon, Eos, Psyche and Artemis. A few others were not certificated.
The oncocyclus Irises are always considered dlfficult to cultivate, and few can grow them to a really successful state. It is much to be hoped that these hybrids will prove easier. The flowers are of the size of the bearded irises, with the same grace of form. The demand here is likely to be great; in fact, that was very evident at the meeting. Under artificial light the quiet colors of the flowers are quite spoiled, and they look very somber, indeed, but in daylight grand.
