The ox eye daisy is a common field and roadside wild flower here in the Pacific North West. It also makes a lovely carefree addition to garden borders, where it attracts beneficial insects and offers nectar to our very important pollinators.
It is reported as being a European immigrant and sometimes as invasive. However, just because a plant that is considered an alien naturalizes itself into a niche in the environment, does not mean it should be considered invasive or even unwanted.
Before considering a plant invasive, ask yourself a few questions:
1. Does it provide pollen and nectar or other food to important pollinators or native animals?
2. Does it provide ecosystem benefits; such as stabilizing slopes, slowing erosion, building top soil, providing animal habitat, or reducing human and domestic animal impacts to the land?
3. Does it increase or decrease the genetic diversity of an area?
4. Is it useful to people for food, medicine, or utility and does it grow where they can access it?
5. Is it crowding out rare or endangered plants or animals?
Let’s apply these questions to our ox eye daisies:
1. Yes it provides nectar to pollinators and pollen to beneficial insects, as well as seeds to birds later in the season.
2. Yes, it provides ecosystem benefits, in that it is often found growing on disturbed slopes, where it helps stabilize the soil and reduces erosion.
3. Simply by its presence it increases the genetic diversity by one, the insects and birds that depend on it may also help increase the genetic diversity of the area.
4. Yes, it is useful to people as food, medicine (see links below), and for attracting pollinators and beneficial insects to the garden and to foraging areas.
5. Probably not, but if so, and someone is committed to tending the threatened native plants, the ox eye daisies should be weeded out with as little physical and chemical disruption to the area as possible.
When we really stop to think about it, many of the plants that are targeted with eradication as aliens or invasive may be better off ignored,or even embraced, used, and celebrated. The eradication activities are often more harmful to the environment than the plants that are removed. For more words of caution regarding being overly quick to judge and destroy plants that are considered alien, as well as a discussion about who profits from their eradication, please see: http://www.jlhudsonseeds.net/NativesVsExotics.htm
Many plants that were once considered alien and invasive have turned out to be indigenous. We owe this knowledge to the botanical archeology conducted on fire pits and midden mounds, as well as cores taken on lake bed sediments. There is no definitive list of all the plants that were here in North America before contact. However, a truly invasive plant is often easy to recognize. A truly invasive plant quickly crowds out other plants and reduces diversity, over a season or over a number of years. And it does it, right before your eyes.
Back to our cheerful ox eyes--I’ve never done more than taste these daisies, so I am not an expert on their use or identification. Not all daisies are edible, and some are actually insecticidal and may be toxic to people too. Always be very sure of your identification of any unfamiliar plant, and study up on the toxic and poisonous plants in your area, so you know what to be cautions of.
