This plant is a stalk about 3 feet tall, and the blooms go up it. Blooms are about an inch. It has been blooming for several months now. It came from a wild flower mix, but is one that I can't identify. It is perennial, or at least biennial.
It's in the mix, so if it looks like it, it is. It is making seed pods now - thin and long. Is that how dame's rockets are?
It is biennial, reseeds itself or you can collect the seeds when the long pods are dry and brown.
hey gabrielle, ive got something like this in the garden, it started coming up in the spring and gets really tall, ive cut it down twice and its still flowering! smells nice too! i got some wild flower seeds last year but i dont remember this coming up then!
