I. danfordioe is another early dwarf, this time yellow, as is I. histrioides, of which the most commonly found variety is ‘Major’ at 4 inches high and with deep blue flowers splashed with yellow in the centre.
I. reticulate, 6 inches, comes in a range of blues: ‘Harmony’ is dark blue, ‘Cantab’ light blue, ‘J. S. Dijt’ a warm purple. A feature of these tiny irises is that they flower when the leaves are very immature and in some cases all but absent. Later the leaves can grow quite tall but by this time you will probably have planted them out in the garden.

Bulbous irises could be planted in a window box but I would rather see them in shallow containers— they need only be planted 22 inches deep—and close together for maximum impact. In a 12 inch pot I would plant a dozen of the tiny bulbs, then put them somewhere where they can be seen close up and also smelled. Read the rest of this entry »
