A lovely tall perennial plant with masses of tiny highly perfumed flowers that makes a great back border plant or in areas where height and flowers are needed. It is very easy to grow and takes little maintenance once established coming back year after year. The flower stalks will most likely need some staking or they flop over, but they produce masses of tiny highly perfumed flowers for a long period that are beloved by butterflies and other beneficial insects, making the task well worth it. Sink a stake in the ground next to each plant and use it year after year. Will spread by underground roots if left to itself, so may need containing. Self seeding does occur but it not too problematic considering the amount of flowers the plant produces.
It prefers full sun but will grow in partial shade. Likes to have good organic matter in the soil, so add a good amount before planting. Once established some top dressing can be done but to create good strong plants every year but its not necessary. if not cut back after flowering. Likes to be in a well drained location that remains slightly moist does not like to dry out or have waterlogged soils. Using a soaker hose to water from the base on a daily basis is ideal. Prefers a neutral pH soil if possible, cannot tolerate waterlogged soils. Plant clumps will increase in size every year and will spread using underground rhizomes so ensure it is planted where spreading is not going to be a problem. Flowers from seed in the second year then just keeps getting better. It's a great low maintenance plant for any garden, why not grow some Valerian yourself this year.
