Persicaria amplexicaulis & cultivar 'Blackfield'
There is a plant sale tomorrow and they might have 'Blackfield' for sale. Does anyone grow it? I don't think this cultivar has been available here (in the US) for very long. If no one grows this particular one I would settle for some general information on any other amplexicaulis Persicaria you grow!
Is it aggressive? I grow other species of Persicaria, just not any amplexicaulis. One site said it needs plenty of room. Not sure exactly how to interpret that, LOL. Is it spreader, or more of an expanding clumper? Would appreciate hearing any and all experiences you have had with this kind!
