'stuttgart' Canna

I got two Canna rhizomes and they sprouted as two plants but now I have 10 plants. They multiplied so quickly. The tallest one is over 7 feet and I love the huge banana like foliage, it gives a tropical feeling. The flowers are in apricot color. I accidently planted them in part shade, looks like that's perfect for them because of the leaves getting scorched if it's very hot. I also read that it's tolerant of wet conditions which is where it is right now. Don't you love when the accidental stuff you do turns out perfect?
