These are sold as late divisions, so may not have a large root system.
Persicaria amplexicaulis 'Blackfield' is a clumping perennial with dark green, oval to heart-shaped leaves to 10cm long. Long-stalked, narrow spikes of dark blood-red flowers open from 
almost black buds from mid summer to mid autumn. Best grown in any moist soil in full sun, so works well in a bog garden, or at the water's edge.
Cut back after flowering, or in late winter/early spring.Some persicarias are much too big for most modern small gardens but this one can be accommodated on smaller plots and has some of the best flowers for depth of colour. 
Foliage: Deciduous
Height: 50-80cm in 2-5 years
Spread: 50-80cm
 
Please read our notes before placing the order:
 
1. The pictures in this listing are examples of the available plant at maturity and do not indicate anything in regard to size of plant at the point of sale. You will receive an organically produced young plant grown in a 9cm pot for planting immediately or to grow on (pot removed, when possible, to reduce plastic waste)
2. Seasonal difference in plants: Please be aware if you are new to gardening, that the plants we supply are mostly herbaceous perennials and many go dormant in winter. You may receive what looks like an empty pot or piece of root. This will produce new growth in spring.
3. The date the Royal mail label is bought (tracking number added as sent against your orders) is the date your order is lined up for picking. It is likely to be put into the post a couple of days later.
 
Thank you.
Size of the plants
Plants are mostly grown in 9cm pots so sometimes there is a need to grow on for the first season to see a mature effect only in the second.
Some older supplied pots may be thick with stems but please note at the other extreme rather than not supply we sometimes send bare root divisions of the size we use for our own potting (continued since Covid stock shortage) usually these are pound or so cheaper than a grown pot. Tips for success are sent with all orders.
Slugs in Summer of 2024 (list deletions)
Most gardeners experienced severe damage from slugs and snails due to the extreme wet and a relatively mild winter. Some genera were not just damaged, but the extra stocks destroyed. We may reintroduce gradually some of the most valued, but others previously listed may remain absent for now.
