Weed Wednesday: Thistle
Happy Weed Wednesday! This week we want to talk about Thistle. Did you know that a Thistle is the national symbol of Scotland and is their oldest recorded National Flower? While there are many types of Thistle, they originate from the same family as sunflowers. You more than likely know thistle by its pointy spines that can stick you. Surprisingly, these spines grow as a sort of armor to protect the weeds from being eaten by wildlife. In the US it is widely known a nuisance weed, that can be tough to control and not something most homeowners like to see among their healthy green lawn.
Thistle is an invasive biennial or perennial weed, meaning it grows every other year, or grows every year depending on the species and can form large infestations quickly. During its life span it can be found growing in fields, home lawns, and roadsides. Plants will typically form stems after growing through at least 1 winter. The stems can grow up to 6 feet tall if left unmanaged and will develop white hairs and deep spines on the leaves. Thistle will begin to flower in late summer to fall for about a month, and produce lavender, pink, or white flowers that typically grow in the shape of a mushroom. Because of its stubborn root system, it can be difficult to remove from your lawn.
If any plant material is left behind it can reproduce and grow back in force the following season. Early detection is key in preventing the growth or spread of seeds. But don’t worry, that’s where we come in.
