'Summerina' is a cross between rudbeckia and echinacea but it's appearance is exactly like an echinacea so i'm not sure why it was named...Read More as a rudbeckia.
Anyway, I bought this plant in late summer and it was a very healthy but slightly expensive 2 litre plant. I left it in the pot over winter (was in normal multi-purpose compost) and it rotted out and didnt comeback in the spring. The winter wasnt particularly wet or cold (uk zone 9, -4c min) yet the plant died so i can only conclude that its much like other echinacea's and it needs perfect winter drainage to survive.
I didnt expect it to die as i never have any problems with rudbeckia's (although echinacea's dont survive well here despite kent being one of the drier uk counties) and other websites describe it as being reliably perennial.
Despite the lovely unique brown flower colour, i can only recommend this if you're in a location that does well with echinacea's.
