(1905) Iris Stylosa Not Flowering

The Garden p.211, April 8, 1905

Iris stylosa not Flowering (E. A.). — The place where Iris stylosa flowers best is against a wall with a south exposure, and which has hot water pipes on the other side, such as the wall of a warm greenhouse. It will, however, flower well planted close up against an open south wall where there are no pipes behind it. It should be planted so that the roots are in contact with the wall, pressed closely up against it. After being transplanted Iris stylosa will often miss flowering for one or two years, but when it is established, and in the position indicated, it will produce an abundance of bloom annually. Manure is not required, a good sandy loam being most suitable. Some forms of this plant bloom much less freely than others, the moat floriferous being the typical form with erect, broad leaves, and the form with narrow leaves (var. angustifolia). The variety speciosa has the largest and most richly-coloured flowers, but does not usually flower so freely.
