When you say "much thinner" do you mean the flowers or the foliage? Was it only the flower that looked like cannas or the whole plant? How tall? Are the leaves all green or variegated? Were they in clumps or single stems? Lot of questions I know, but it might help to ID this plant.

The flowers and the leaves were thinner. It was about 4 feet tall. The leaves were solid green. They were single stems, but grew in huge clumps, as if they multiplied like cannas. Thanks in advance for helping!!

With a photo we could help you in a flash. It 'could' have been a Heliconia psittacorum I suppose, but without a photo, it's hard to say.

YES!! That is it!! Thank you!! You're so good you didn't even need a photo! ;)
