PLEASE NOTE: Since plants are often sourced from the garden to order, sizes do vary a little, depending on how they come out of the ground, but I always endeavour to give a little more rather than less! They are sometimes shipped bare-rooted, but will approximate the size specified (e.g. a 9cm pot).
|Persicaria bistorta 'Superba'|
|Red bistort 'Superba'|
|Soft spikes of tiny pink flowers on straight stems from May and well into the summer, above broad, deeply veined, grey-green leaves. Makes good ground cover. Spreads rapidly by underground runners but these are not far beneath the surface, so are easily removed in open ground as required.|
|Sowing and/or growing instructions|
|Sow thinly under glass, Jan-Mar in good quality, soil-based seed compost, covering with a thin layer of sieved compost or fine vermiculite. Cover with plastic or place in a propagator at 20C/68F. Germination should commence in 28-42 days, but can be slow and erratic. If germination does not occur, try chilling the sown seeds in a fridge for 4-6 weeks, then return to warmer conditions. Grow on in cooler conditions, planting out after all risk of frost has passed.|
