Persicaria bistorta 'Superba'
- Position: full sun or partial shade
- Soil: any moist soil
- Rate of growth: fast-growing
- Flowering period: June to October
- Hardiness: fully hardy
Dense spikes of soft pink flowers rise from midsummer to early autumn above semi-evergreen, deeply veined, mid-green leaves. This clump-forming, vigorous perennial has handsome foliage and quickly makes dense groundcover in sun or partial shade. Plant it in bold swatches to add vertical interest in the border right through till mid autumn, and give it plenty of space. Persicaria does not like dry soil, so performs best in a bog garden or beside a pond. Bees and other insects love it too!
- Garden care: Lift and divide congested colonies in spring or autumn.

Comments about Crocus Persicaria bistorta'Superba':
A fantastic, vigorous plant that's a joy to behold. 2 months ago this plant had completely died back to the ground after winter (so very much deciduous in Manchester!), and now it's a huge mass of lush green leaves with a few dozen pretty pink flower spikes.
We can go up to it at pretty much any time of the day and find several bees working it, which my 2 year old daughter loves to watch.
It's really flourished in one of my boggier beds and the sheer vitality of the plant really is something to see. Fully deserving of the RHS merit award.

Q:Help for a shady damp spot please
Hi I'm looking for plants for a damp shady spot in my garden. It's a raised, north-facing bed and stays damp most of the year, and the soil is compost-rich. I'd love to get some colour in there as I look out on to it from my kitchen window so I was wondering about Hollyhocks, Flag Irises or maybe Heuchera? I also have a very big slug problem though - tried Sambucus nigra last year and it was eaten! Please, what can you suggest? I look forward to hearing from you. Kind regards MaryAsked on 24/7/2009 by mary culhane
A:Hello Mary, Most flowering plants prefer a sunnier spot, and few plants can cope if the soil remains too wet, however you could consider any of the following Alchemilla http://www.crocus.co.uk/search/_/search.alchemilla/ Ferns http://www.crocus.co.uk/plants/_/ferns/plcid.309/ Helleborus http://www.crocus.co.uk/search/_/search.helleborus/ Hydrangea http://www.crocus.co.uk/search/_/search.hydrangea/ Persicaria http://www.crocus.co.uk/search/_/search.persicaria/ Rhododendron http://www.crocus.co.uk/search/_/search.rhododendron/ Vinca http://www.crocus.co.uk/search/_/search.vinca/ I hope this gives you a few ideas.
