I don't find it exactly objectionable, but this is a very unremarkable plant with neglibible flowers and foliage substantially less interesting than most of the decorative plants of the genus.

I 've succesfully sown Greenfinch under a cold frame...they also reseed a lot..lots of new seedlings I have to pull out every spring. They 'll look great in a natural garden with filtered sunlight.
