Persicaria 'Silver Dragon'

Trial: Perennial
Year Trialed: 2004, 2005
Good Qualities:
Year 1
Very attractive foliage, long bloom period (all summer) very good vase life, not attractive to vermin; Tall, good color; Nice flower.
Year 2
I like these plants as a group, vigorous nice foliage, interesting and there aren't a lot of these sold as cut flowers around yet.
Problems:
Year 1
The flowers were nothing to look at and foliage is pretty but not long enough to use for cuts; Deer love it, japanese beetles also; Time consuming to harvest.
Year 2
I was surprised by the mortality over the winter - I was actually more afraid that these would escape and become a weed problem.
