Viburnum dentatum – Arrowwood Viburnum
Easily grown in average, medium, well-drained soil in full sun to part shade. Prune immediately after flowering since flower buds form in summer for the following year.
Arrowwood viburnum is an upright, rounded, multi-stemmed, deciduous shrub which typically matures to 6-10′ tall with a similar spread, but may reach a height of 15′ in optimum growing conditions. Non-fragrant white flowers in flat-topped corymbs (to 4″ diameter) appear in late spring. Flowers give way to blue-black, berry-like drupes which are quite attractive to birds and wildlife. Ovate, toothed, glossy dark green leaves (to 4″ long). Variable fall color ranges from drab yellow to attractive shades of orange and red. Although widespread in eastern North America, this native plant is only known to exist in the wild in Missouri on wooded slopes along the Salt River in Shelby County. Native Americans reportedly used the straight stems of this shrub for arrow shafts, hence the common name.
No serious insect or disease problems.
Zizia aurea – Golden Alexanders
Zizia aurea is one of those natives that every garden should have. It is fairly easy to grow and, although short-lived, will self-seed and persist in many sun/soil situations. Zizia is an important plant to a number of short-tongued insects that are able to easily reach the nectar in the small yellow flowers. Black Swallowtail caterpillars will feed on its leaves.
Golden Alexanders have a long bloom time, giving the garden/prairie some well-deserved early color for several weeks in late spring to early summer when many other plants have not yet flowered. Also called Golden Zizia, Golden Alexanders will tolerate a lot of shade but prefer full sun or light shade.
