'Buttered Popcorn' was the most showy cultivar in my first-year garden. The color is absolutely stunning, and it was the tallest one in my garden though not as tall as the stats suggest (32"). The bloom stats are 6", and mine were only about 5". Mind you, this is a first-year garden with 'Buttered Popcorn' planted in May and showing me its four blooms about a month later. I'm looking forward to seeing the real show of 'Buttered Popcorn' next year! I had no rust to worry about, and she certainly grew well this year.
