One of my favorite snapdragons to sprout from seed is ‘Night and Day.’ It’s a descendant of the heirloom ‘Black Prince’ with beautiful crimson-black flowers and a contrasting white throat.
‘Night and Day’ grows 18 inches tall in sun or part-shade and is a bumblebee favorite. It never gives me any problems with pests or diseases. If deadheaded, it blooms all summer long.
