"One of the most attractive ways of using Dichroa 'Blue Sapphires' in the garden is as a companion to hydrangeas. Try mingling it with a variety that has lighter blue flowers and is lower growing, such as 'Birgit Blue', and a tall growing white variety. Add a large flowered hybrid clematis, planted at the base of the Dichroa, and you will have an amazing and lengthy flowering performance from them all.
Tall stemmed, large flowered campanulas are among many perennials which look good planted as a foreground to Dichroa 'Blue Sapphires'. The large, grey-blue, bell shaped flowers of Campanula 'Mystic Bells' are produced for a long period as are those of the similarly shaped, deep-purple blue variety 'Kent Belle'.
Penstemons, which flower all summer and come in a pleasing range of pink, white, wine-red and grape colourings, are also a delight to grow near Dichroa 'Blue Sapphires' in sunny situations. In lightly shaded areas, the bold foliage of native renga renga, Arthropodium cirratum 'Matapouri Bay', looks good with Dichroa foliage and flowers, especially in early summer when the renga renga produces its bounty of long stemmed cream flowers.
There are some exciting new perennials to try in such a situation too. The yellow foliaged, blue flowered Centaurea 'Gold Bullion' can be used as a striking ground cover, as can the new, cold hardy, cranesbill Geranium 'Rozanne' which is smothered in gorgeous blue flowers over summer and into autumn. Upright, taller growing perennials to contemplate for dramatic flowering performances and appearance include the new Hammett Dahlia varieties 'Scarlet Fern', with divided, mahogany coloured foliage and single, scarlet flowers, and 'Knock Out', with gold flowers made all the more dramatic by the dark coloured foliage."
