It's been a funny year... morning glory has actually grown from last years seed in the allotment... had it happen in a cold greenhouse but never in the open soil... 
			
			
			
				I've had some Nicotiana that has just carried on flowering all though the winter since I sowed it last year!
			
			
			
				Same here with some Night Phlox... didn't even realise it was technically a perennial...
