I saw this plant the other day and want one. I have searched but haven't found it. It is 5 foot tall with dark red and green leaves with bright orange flowers in a cluster at the top. ( photo / image / picture from browntnthumb's Garden )
That's a Canna X generalis (Canna Lily) Some call it a Canna Lily but it is not a lily. That one is specifically is a Canna 'Tropicana'
