I love this plant - every year it just gets better. I have found that deadheading will keep the bloom time going a bit longer.

Prolific grower, covered with blooms, not bothered by diseases. Covered with butter yellow flowers. One note is that it doesn't have "terribly" long bloom time but its bloom time is decent. ;) :)
