What’s the best part of being a wildlife gardener besides the wondrous wildlife we attract? Nothing. We have all we need in the natural world to provide local wildlife diversity, but we can always plant more.
Diversity is essential to a healthy ecosystem, and that is the goal of a wildlife gardener. We want our gardens to do more than look good. We need to provide ecosystem services, and adding genetic diversity to the plant population strengthens the ecosystem.
For wildlife, the preferred species are straight, native species, and some cultivars that benefit wildlife. To understand this, here is a short description of straight species, cultivars, navitars, and hybrids.
Straight Species—Native Plants
By definition, a straight species is considered a native plant, one that occurs naturally in a given location or region. Native species are adapted to the local climate and soil conditions where they naturally occur, and native plants provide the most benefit to the wildlife.
These essential plant species provide nectar, pollen, and seeds serving as food for native butterflies, insects, birds, and other animals. An example of a straight species native to the eastern and central United States and eastern Canada is the garden phlox, Phlox paniculata.
Cultivars
Straight species garden phlox has been extensively cultivated as an ornamental plant. Cultivars are the portmanteau of the cultivated variety. Cultivars are almost always clones, but not necessarily. Clones may sound space-age, but it’s something we do every time we divide a perennial. Commercial cloning is through root cuttings.
It’s also important to note that cultivar seeds collected in your garden may not come true. If you are planting species that self-seed, like bee balm or many asters, many cultivars won’t come true from seed.
Nativar
Nativars are nothing more than a cultivar of a native species. For some reason, purists find this term distasteful.
The term may be redundant since all nativars are cultivars, but not all cultivars are nativars. The term suits me because it distinguishes a native plant, and the more this is reinforced, the better.
Depending on the plant, some of these cultivars/nativars are botanical oddities that are highly regarded by the nursery industry, particularly those with double flowers. In the breeding or selection of double flowers, the petals replace the stamen. An example of double flowers is the coneflower, Echinacea purpurea ‘Pink Double Delight’. It’s difficult, if not impossible, for bees and butterflies to gather pollen or nectar from double flowers if there is any left at all. Such enhanced blooms can also be sterile and unable to produce seeds—bad news for the goldfinches and other birds that relish these nutritious treats.
Hybrids
Let’s add to the confusion—there’s the prevalence of hybrids, which are crosses between multiple species. Hybrids will be indicated with an ‘×’ after the genus and before the cultivar name, such as Coreopsis × ‘Redshift’. Here, I am a purist, but I don’t know why. That × is actually the multiplication symbol, meaning it is a cross between two or more species.
As you plan your pollinator garden in the new year, choose straight species or other species that haven’t been messed with the amount of pollen and nectar in the plant. So, as pretty as those double flowers are to see, they won’t benefit the wildlife much.
