I think this is one of the prettiest blue wildflowers in North Dakota.

 

This common plant is a magnet for butterflies. In addition, it’s excellent for cutting and drying.

 

The Bachelor’s Button flowers are daisy-like and virtually pest and disease-free. And can you believe they are also deer and drought tolerant?! I recommend this easy-to-grow plant for borders of flower beds or rock gardens.

This non-native blue wildflower is found throughout North Dakota. Typically you will find this plant where it’s sunny and dry, so look for it along roads and open fields.

 

The exciting thing about Chicory is it is eatable. The leaves are high in vitamins and minerals. You can eat the leaves as a vegetable or in a salad, but beware, they are very bitter tasting. The roots can also be boiled and eaten with butter. Sometimes the root is roasted and ground as a substitute or additive to coffee.

 

Interestingly, Chicory flowers only bloom for ONE day. And in hot weather, the flower may only be open for a few hours!
