Know before you buy
Marginal plants are designed to grow in the shallow edges of a pond, typically in water depths of up to a few inches. They act as a bridge between your water feature and the surrounding landscape, helping to soften the edges of the pond liner.
The Obedient Plant thrives in shallow water. You should place the pot so that the water level reaches just to the top of the soil or slightly above the rim, ensuring the crown of the plant remains moist but not completely submerged.
Yes, as a hardy perennial, it is well-suited for outdoor environments. It is rated for hardiness zones 5 through 11, meaning it can withstand cold winters in most regions of North America.
Since this plant grows upright to a height of 36 inches, it works best when spaced about 12 to 18 inches apart. This allows enough room for the stalks to develop without overcrowding the marginal zone.
For the most abundant lavender flower stalks, this plant prefers a location with full sun to partial shade. It will perform best when it receives at least six hours of direct sunlight daily.
