I like Intrigue for its foliage, burgundy with tinges of green. Constitution I like for both the flowers and the foliage and Wyoming for the deep red flowers. I also like Indian Shot for the foliage, which is a mixture of green and burgundy, too. Stuttgart have nice varigated foliage.

It all depends on what your individual taste is in color of flowers and foliage. For example, I don't like pink or white flowers and I would therefore not recommend them. I suggest looking at the flowers/foliage on a site such as the site below. - Mike

I like the the species-like cannas: Canna x iridiflora 'Ehemannii', Canna 'Robert Kent' (or a similar name), whatever Yucca Do has on offer, Canna 'Erebus'.

Admittedly, orange flowers are not for everyone, but you simply must have Canna 'Pretoria' (aka 'Bengal Tiger) for the gorgeous foliage! It's my number one Canna. Though I think that I think of them as foliage plants anyway.

'Cleopatra' is interesting too. It's leaves are purplish and green, sort of swirled. If the flowers come from the green side they are yellow. If they come from the purple side, they are red. A conversation piece at the very least.

I'm sure you will enjoy whichever Cannas you choose!

PS. Plant Delights Nursery has a fun and informative
webite, with lots of Cannas as well as other "plants with an attitude".

Also you might want to decide on some by height, depending on where you are putting them in your garden.

Intrigue, Tall 6' purple leaves and stately appearance
Bengel Tiger - Yep the pretty leaves
Tropicanna - Grown in good fertilized soil the colors are simply beautiful
Stuggart - Again you cannot beat the leaves
Cleopatra - Varigation and a big colorful flower
Tropical Sunrise - Pretty peachy colored blooms.

I grow most of the Cannas for the leaves. The flowers are usually not that impressive IMO.

I too grow Cannas for the foliage rather than the flowers, which always look like untidy Gladioli to me.
For the huge foliage I love Canna Musifolia, 7-8 feet high in the UK and unlikely to flower. I also overwinter Canna Indica at 5-6 degrees C minimum, which keeps them green and alive, so that they too grow to 6-7 feet the next year, with large leaves but no flowers. This winter I will be trying Tropicana, as their leaves are much more interesting. A new overwintering house is coming on stream "real soon now", Ive poured the concrete base, so there might be room to try overwintering the Musifolia. Heaven knows how tall that will get if I succeed.
