Valeriana rotundifolia

Mountain valerian performs best when exposed to abundant light. It can tolerate a little shade, but constant sun exposure encourages healthier, more vigorous growth. Native to well-lit habitats, it is adapted to those conditions. Excessive sun can cause it to dry out, while insufficient light can limit its development.

Mountain valerian is native to regions with mild climates and grows best when temperatures range from 41 to 89.6 °F (5 to 32 °C). Taking steps to avoid extreme temperatures, especially in summer and winter, is essential for its health.

The best time to fertilize a Mountain valerian is in early spring, as it comes out of dormancy and begins active growth. Fertilizing supplies essential nutrients needed for healthy development. While Mountain valerian has relatively low fertilizer requirements, an annual application can improve its survival and encourage better, longer-lasting flowers.
