A new variety of the sxtremely robust hardy perennial and ideal choice for difficult sites with poor soil or with limited sun light.
Clumps of mid-green foliage act as a great foil for the very dark, slender red flowers held on tall stems in mid to late summer. The tips of the flower spikes are almost black and then open to darkest red and the flowering period may be as long as mid-summer until October. The flowers will attract both bees and butterflies.
Persicaria was formerly grouped with Polygonum before the taxonomists thought the better of it, and has in the past had a reputation of being a 'weed' - whatever that means! Actually, its slightly thuggish, and certainly very robust, nature is one of its most valuable attributes because it can thrive where other more demanding plants might just give up.
Persicaria amplexicaulis 'Blackfield' will form bold clumps, up to one metre across - these can be readily split in the spring for propagation.
Fully hardy. Height: flowering stems up to 1.2m
