Cryptotaenia. japonica 'Atropurpurea'.

This has come in as a hitch hiker in a recently bought plant. Any advice on how to grow it, behaviour etc.
thanks in advance.




New one on me, never heard of it before, but I've done a bit of research, though probably haven't found anything you've not found yourself. One site says it 'prefers moist conditions with a bit of shade, but will grow almost anywhere' and its hardy down to -16 deg C, but another site says it likes sun, well drained soil and is hardy down to -10 deg. C. Perennial, umbelliferous, toxic if eaten, that's about it, couldn't find anything else. Not mentioned in my RHS encyclopaedia at all...

that's what I did find Bamboo, except some said it was an edible herb, I was hoping some one grew it and could say from experience. Several of my new purchases aren't in the RHS bible either. Don't intend to eat it though. :o)
I has an unusual leaf colour. cant decide if it will show up on my soil though.

That's the trouble with dark leaved plants, they only show if they get tall against green surroundings.

Conflicting and possibly dangerous info. So annoying.

I get what you mean, Merlinbaby... its definition as a 'herb' (which it is classed as) sort of implies it okay to eat, but remember, many 'herbs' are dangerous if consumed, and are actually only herbs in the medicinal sense - penny royal or feverfew being examples. The confusion is because you rarely see the full definition, which is either culinary herb, or medicinal herb.
