Tarragon

Tarragon (Artemisia dranunculus) is a cold hardy perennial herb native to our area. Here is its entry in the Montana Field Guide. It truly has a really delicious flavor and we use it on pizza, roasted chicken and veggies, soups and pastas, etc. 

It grows in a clump, gets 4 to 6 feet tall, and dies back to the ground in the winter. 

These are 3rd year root crowns with a bit of stem attached.
