Summerinas are a recent intergeneric hybrid. We have trouble with this plant's parents- echinacea and rudbeckias- because they tend to be dry prairie type species and we are well, a dampish coastal situation on the other side of the fucking planet. They'll do alright in a hot year and then rot down into slimy little grey masses the next, which is a shame because the plants are somewhat expensive and very lovely when successful. I splashed out on two summerinas this year and they dutifully put forth both marigold-yellow and these deep mahogany red blooms; it remains to be seen if they will prove as perennial as their nursery bumf claims.
I highly recommend them if you're in a hot dry spot and like a nice showy late season daisy; their colours are pretty unique and highly saturated, providing great contrast to the fleshy turquoise and emerald of xeriscape species etc.
