This plant came with the property and I'm sure it was an old favorite in the past yet can't actually find it in research.
It gets over 3 feet tall and has leaves over a foot long.
Unfortunately I did not photograph the blooms this year. They come on a single tall spike about two feet above the plant and the flowers open at the same time in an attractive fluffy floral display that is long lasting and are white.
Thank You!
