Japanese Bloodgrass - Does anyone grow the Imperata cylindrica 'Red Baron' grass? It's one of those plants you see somewhere and decide you MUST have. Having now bought a pot I am wondering if it is invasive, do I need to keep it in a pot? Just asking as I 'googled' it in the past and found it was banned in some states of America as it was swamping the native floral. Is this the same sort, or different?

It does tend to spread if left to its own devices. Not excessively, but one of those that you suddenly realise is taking up rather more room than you want it to. I divided mine up two years ago.

Thank you both for your answers. Two thoughts to go with! Norfolk can be quite bleak so it could be vulnerable to the cold and sharp winds.
As I have a fairly big pot full I think I will put some in a sheltered spot and keep some in a pot!

Mine didn't reappear the year after I planted it - certainly not invasive here!

Mine are in a 'gravel' bed (whitish smallish stones), and the Imperata is often admired by visitors. It has spread slowly over the years, but needs no maintenance, and as it isn't in a border is not in danger of being dug up when it disappears for the winter! Good idea of yours to keep some in a pot Honeysuckle.

Don't know about invasive but didn't survive winter up here.
