Al's Peach Tower--Listed at 59" with 7" flower, and it is every bit of that. Flowers are so heavy scape does need staking, but can i blame it? No! It's the tallest!
Love Song--Listed at 38", but blooms up to 42" for me. Flowers are Big, but held well by the strong scape.

Buddy's String Bean--40" and gets to that height
Lightning Storm--40" sometimes a bit taller
