White Broom is in flower from the middle of May to the second week of June. There is a fine Flag Iris of a rich purple colour called "Purple King." It is well to grow it just in front of some young bushes of White Broom. Then, if one of the hybrid Irises of pale lilac colour is there as well, and a bush of Rosa altaica, the colour-effect will be surprisingly beautiful. This Rose is the bolder-growing, Asiatic equivalent of our Burnet Rose (R. spinosissima), with the same lemon-white flowers. When any such group containing White Broom is planted, it should be remembered that the tendency of the Broom is to grow tall and leggy. It bears pruning, but it is a good plan to plant some extra ones behind the others. After a couple of years, if the front plants have grown out of bounds, the back ones can be bent down and fastened to sticks, so that their heads come in the required places. It is one of the many ways in which a pretty garden picture may be maintained from year to year by the exercise of a little thought and ingenuity. The undergrowth of such a group may be of Solomon's Seal at the back, and, if the bank or border is in sun, of a lower groundwork of Iberis and Corydalis ochroleuca, or, if it is shaded, of Tiarella, Woodruff or Anemone sylvestris. With these, for the sake of their tender green foliage, there may well be Uvularia grandiflora and Epimedium pinnatum. There is now a dwarf form of the White Broom, a plant not only less in height but of a more close and compact shape, that is useful for grouping in front of the older, taller one as well as for use in places where the original plant is too large.
