This rapid growing upright perennial grows in clusters up to two feet high, offering abundant pure white snapdragon shaped flowers on tall, stiff stems that will brighten any moist place in your garden, sun or part shade.
The flowering stage is continuous with flowers lasting a long time. The plant resembles wild meadow flowers and thus is a perfect choice for mass plantings. The bright white flowers are "self cleaning" which means they do not brown or fade as they age. They do very well in containers, especially as an accent for other colorful flowers. Just make sure they get watered as they like a well drained, but moist soil.
The reason the plant is called "obedient" is that the flower tips can be gently bent and they will stay that way. They are friendly in other ways, too: they make excellent cut flowers, butterflies love them, and yet they are rabbit, squirrel and deer resistant.
