My recommended 'Buy' of the season:
Easter Morn (Longiflorum X Trumpet) triploid

This cultivar is absolutely admirable in all respects. Robust and sturdy, a beautiful well proportioned plant with dark green foliage that requires no staking. High bud count of very well placed large flowers with heavy substance that last for days without fade or color shift. Lightly fragrant. About 5 ft. Very garden hardy. Blooms late June/early July. Blends well in a mixed garden setting.
I've been growing these for three years in a couple different gardens here in Wisconsin--zone 5A/5B; one of those gardens is in full sun from sun up to sun down without any shade whatsoever except a passing cloud. During last years heat spell of several consecutive 100'F plus days, the flowers and buds did not burn at all. Here's a closer look.
