Nativar, short for “native cultivar,” refers to a particular type of plant that is derived from native parents and bred for specific characteristics. This term is commonly used in gardening and landscaping to describe plants that have been selected or cultivated for certain traits, such as unique flower colors, improved disease resistance, or compact growth habits.
The concept of nativars can be a bit controversial, as it involves manipulating the genetic diversity of native plant species for human preferences. Unlike true native plants, which occur naturally within a region as a result of natural processes, nativars are the product of human intervention. This breeding process often leads to a loss of genetic diversity, as the focus is on selecting and propagating plants with specific traits rather than maintaining the natural variability of the species.
One of the potential concerns with nativars is their impact on pollinators and other wildlife. Native plants have evolved alongside local insects, birds, and other animals, forming intricate relationships and providing essential food and habitat. While nativars may retain some of the characteristics of their native parent plants, they can also exhibit changes that make them less attractive or beneficial to native wildlife. For example, nativars may have sterile flowers, producing no seeds or nectar, which can negatively impact pollinators.
It is important to note that not all nativars have negative consequences. Some nativars are bred with the intention of enhancing the traits that make native plants valuable to wildlife. These nativars may still provide essential resources for pollinators and other animals, despite being selectively bred. However, it is crucial to carefully evaluate the impact of each specific nativar on the local ecosystem before incorporating them into garden or landscaping designs.
In my own experience as a gardening and landscaping enthusiast, I have encountered nativars in various settings. I have seen gardens filled with nativars that boast vibrant flower colors or compact forms, adding visual appeal to the landscape. However, I have also observed the absence of pollinators and other wildlife in these gardens, highlighting the potential drawbacks of nativars. On the other hand, I have come across nativars that have been bred specifically to attract butterflies or support other native wildlife, and these have proven to be successful in creating biodiverse and sustainable landscapes.
Nativars are cultivated plants derived from native parents and bred for certain traits. While they can offer unique characteristics and visual appeal, there are considerations regarding their impact on genetic diversity and native wildlife. Careful evaluation and selection of nativars can help minimize negative effects and promote a more sustainable approach to gardening and landscaping.
