Millettia japonica 'Hime fuji' Spreading 6 Vine Green Translated, the name of this shrub is “dwarf wisteria,” but similarity to that robust vine is limited. It does have narrow, green-bronze leaflets reminiscent of wisteria, but it is much smaller and performs in places that could never accommodate a big, heavy vine. The tender, tropical shrub needs rich, moist soil and ample water in summer. In colder climates, grow it in a container that can be moved inside for winter. Trim off any errant climbing shoots.

In early spring, the stems are adorned with small buds that swell larger and larger until blood red catkins open and expose tiny bright yellow anthers. Salix lindleyana prefers very well drained soil and full sun to partial shade.
Spiraea japonica 'Bullata' Globe Shaped 4 Small Bush Green This dwarf spiraea, an underutilized heirloom that dates to 1881, is a uniquely compact shrublet with a broadly ovate shape, small, dark green leaves and bigger flower clusters than might be expected on such a small plant.
