Impactful Shrubs

 

What’s in your yard? You probably don’t have room for everything you want, but small and urban yards can plan to maximize the wildlife value of their plantings. We talk about trees a lot, but shrubs can provide good ecological value for smaller spaces. Here are some thoughts on impactful shrubs to plant that make a difference.

Impactful means that they contribute to the food web in one of 3 ways: their fruit is good for wildlife (like birds), their foliage serves as a host plant to insect herbivores (like caterpillars), and/or they are a good source of pollen/nectar for insects (like bees and butterflies).

Shrubs that support frugivorous birds (those who use fruit as a major source of their adult nutrition) include native viburnums (Viburnum spp.), hearts a bustin’ (Euonymus americanus), spicebush (Lindera spp.), elderberry (Sambucus canadensis), holly shrubs (Ilex spp.), chokeberry (Aronia spp.), shrub dogwoods (Swida amomum, C. foemina and others), St. John’s wort (Hypericum spp.), beautyberry (Callicarpa americana), blueberry (Vaccinium spp.), huckleberry (Gaylussacia spp.), and sumac (Rhus spp.).

Shrubs whose foliage serves as a host plant to butterflies and moths (these feed caterpillars) include spicebush (Lindera spp.), blueberry (Vaccinium spp.), plums (Prunus spp.), and paw paw (Asimina spp.). Some of these support specialist insects like the Zebra swallowtail that can only use paw paw.

Shrubs whose flowers are a good source of pollen or nectar for bees and butterflies include native viburnums (Viburnum spp.), buckeyes (Aesculus spp.), elderberry (Sambucus canadensis), holly shrubs (Ilex spp.), chokeberry (Aronia spp.), shrub dogwoods (Swida amomum, C. foemina and others), St. John’s wort (Hypericum spp.), blueberry (Vaccinium spp.), huckleberry (Gaylussacia spp.), buttonbush (Cephalanthus occidentalis), and sumac (Rhus spp.).

You can see that some plants might serve 2-3 ecological purposes (for example, blueberry and spicebush support both birds and insects), allowing smaller yards to benefit from these shrubs quite a bit. Make your choices count!
