Wavy Leaf Thistle

• The Wavy leaf thistle is probably the most common thistle since it is native to Kansas.
• It has a pale pink flower with a base shaped like an urn which makes the flower resemble the shaving brush and is in bloom from May to July.
• The leaves are covered by fine white hairs giving them a dusty appearance.
• Although this plant spreads by both roots and seeds, it is seldom a problem.

Bull Thistle

• The Bull Thistle is also common in Dickinson County.
• It is a hairy, dark green perennial plant that blooms from August to September.
• The shaving-brush-like blooms are usually purple.
• This plant spreads rapidly in pastures if not controlled.

Tall or Roadside Thistle

• The Tall or Roadside thistle is the other commonly occurring thistle found in this area.
• It is easily distinguished by a leaf that is dark green on top and silver on the bottom side.
• These thistles are common along roadsides as the name implies.
• They bloom in August and September, but seldom cause production losses.
