BULL THISTLE Cirsium vulgare

Bull-Thistle-DSC_2715.jpg (122288 bytes) 

Bull Thistle is a prickly wildflower with prickles all along their stems and leaves. The branching stems of the Bull Thistle are kinda square and four-sided with prickles everywhere. There is just NOT a good place to grab this plant when you're trying to pull it. It also has a monstrous huge tap root.

The Bull Thistle is a biennial plant, which means it lives for two years and then dies. The first year it grows a rosette, a whorl-like cluster of leaves near the ground. The second year it grows flowers and fruits, spreading seeds before it dies. 

Bull Thistles are a good food source for many animals and birds. Rabbits and deer eat the leaves and stems. Flower nectar is consumed by hummingbirds, bees, and butterflies. Seeds (called "thistledown") are popular with many birds, such as American Goldfinches and Juncos, as well as mice and other small mammals. You can purchase bags of thistle seed for your birdfeeders.

Bull Thistles are pollinated by insects and birds gathering pollen from one plant, and passing it on to the next one they visit.

Bull Thistles have purple to pink flowers, one to two inches wide, which sit on a bulbous (and prickly) bottom. The leaves are longer at the bottom and can reach lengths of 8-10 inches. Bull Thistles can grow six feet (two meters) tall. When the blooms are spent, the plant produces seed that is carried by the wind. Bull Thistle blooms from July to September.

This plant, which is in the Sunflower family, can grow in fields, gardens, and roadsides. It is not a native plant but seems to grow wherever there is disturbed soil and can take over a logged-off area (along with Hound's-tongue Burr). Some gardeners, who plant to attract wildlife and insects, will place Bull Thistle at the rear of their planting areas as a pretty backdrop to lower-growing plants.

I've often though Bull Thistles would make a great hedge - it would sure keep anything out that you hadn't invited!
