(1909) Dutch Irises
Florist's Exchange p.178, Vol. 28, 1909
Dutch Irises. Messrs. de Graaff Bros., Leiden, Holland, send us particulars of a new race of early giant Xiphiums, flowering fully a fortnight in advance of Iris Hispanica. This race of Iris is best described as a giant strain of very early flowering Iris Hispanica. but in all respects greatly superior to these, as the flowers are of enormous size and remarkable substance ; the foliage is very broad and of a glaucous green. The range of colors is as much varied as with Iris Hispanica; some of the varieties have delicate, soft shades of blue and white while the deep blues are very showy, being of an exceedingly rich toue, relieved by a large massive golden-orange-yellow central spot. Their time of flowering is two to three weeks before even the earliest Spanish Iris, which is very important. These new giant Xiphiums want the same soil as Iris Hispanica or Anglica, and are best planted end of September. In very cold districts they want protection against frost.
