Valeriana montana, the mountain valerian, is a species of flowering plant in the family Caprifoliaceae. Native to the mountains of Europe from east-central Spain, southern Italy, the Alps, the Balkans, and on to the eastern Carpathians, it is available from commercial suppliers.
Mountain valerian is fairly resistant to disease and generally not prone to illness. Still, it can be affected by pests and diseases present in its environment. Such infections are usually mild. In terms of care, this plant needs a moderate level of attention. It should be pruned regularly to keep a tidy appearance and support healthy growth. Fertilizing can also help encourage flowering. Mountain valerian is suitable for anyone with outdoor space, like a garden or patio, and does not require extensive experience in plant care. It may demand more attention when grown indoors.
How to keep Valeriana Montana.
Light
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.
Water
Mountain valerian thrives in alpine habitats, where it prefers regular moisture and cool conditions. Ideally, it should be watered weekly, although it can tolerate short periods of dryness. While it is typically grown outdoors, mountain valerian adapts well to cooler climates. During its dormancy in the colder seasons, it requires less irrigation.
Temperature
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.
Fertilizer
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.
Pruning
Mountain valerian showcases tall clusters of white to pink flowers and has aromatic foliage. To encourage growth, prune it in early spring by cutting the stems above the ground. In late spring, remove the spent flower heads. Make sure to clean your tools to prevent disease, which will help promote more blooms and better manage the plant's size.

Reader questions.
What do I need to do if I give my Mountain valerian plant too much or too little water?
Overwatering is a more common issue for Mountain valerian and can lead to wilting, yellowing of leaves, and diseases like root rot, mold, and mildew. Underwatering is less common but can cause brittle, brown leaves. It's important to notice signs of overwatering early and reduce watering immediately. If the soil drains poorly, replace it with a well-draining mix. If underwatering is the issue, water more regularly until signs improve.
Why should I add fertilizer to my Mountain valerian?
To help your Mountain valerian thrive and maintain its beautiful appearance, proper fertilization is crucial. The leaves of the plant form its main structure and play a significant role in its overall health. Fertilizing the soil not only ensures consistent leaf color and a healthy texture but also benefits the plant below the surface. It encourages the growth of new roots and sustains the existing ones, enabling the plant to absorb nutrients efficiently in the future. By fertilizing your Mountain valerian, you are not only keeping it healthy now but also setting it up for long-term success.
What are the sunlight requirements for Mountain Valerian?
Mountain Valerian thrives best in full sun, requiring more than 6 hours of sunlight daily. It can also tolerate partial sun, approximately 3-6 hours of sunlight. Observing the movement of sunlight through the garden and selecting locations that offer a balance of light and shade are crucial for the plant's well-being. In its natural habitat, Mountain Valerian is adapted to environments with plenty of light, promoting healthier growth. However, overexposure may lead to desiccation, while insufficient light can hinder its growth.
What is the ideal temperature range for mountain valerian?
Mountain valerian thrives best in environments with moderate climate conditions, with an ideal temperature range between 41 to 89.6°F (5 to 32°C). It's important to make adjustments to avoid temperature extremes, especially during the summer and winter months, to maintain the health and well-being of the plant.
How frequently should I water my Mountain valerian?
If your Mountain valerian is in a pot, the best way to check if it needs water is to stick your finger in the soil. If the top two to three inches of soil are dry, then it's time to water it. If you have your Mountain valerian planted outdoors, you can use the same method. When the top few inches of soil are dry, it's time to water. Typically, during spring and early fall, you'll need to water this plant about once a week using this method. However, in extremely hot weather, you may need to water it twice or more per week. It's worth noting that mature, well-established Mountain valerian plants can handle drought conditions well.
When should I fertilize my Mountain valerian plant?
If you choose to grow your Mountain valerian outdoors each year, you will notice new growth appearing in early spring. This is your signal to start fertilizing for the year. Typically, a single application of fertilizer in the spring is sufficient for a healthy Mountain valerian. However, if you want to encourage maximum growth, you can fertilize multiple times throughout the spring and early summer. In this case, it is recommended to fertilize your Mountain valerian every month to a month and a half.
How does artificial lighting benefit indoor Mountain Valerian plants, and what are the recommendations?
Indoor Mountain Valerian plants require adequate lighting for optimal growth, especially when natural sunlight is insufficient, such as in winter or less sunny spaces. Artificial lights, like LED lights, are recommended because they can be customized to provide specific wavelengths needed by plants. Full sun plants need 30-50W/sq ft, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft of artificial light. The light source should be placed 12-36 inches above the plant, mimicking natural sunlight, and most plants need 8-12 hours of light per day.
Does mountain valerian need frost protection during winter?
Mountain valerian is highly cold-tolerant and does not require additional measures for frost protection during the winter. However, it is advised to water the plant generously before the first freeze in autumn. This ensures the soil around the plant remains moist and enters a frozen state which helps prevent drought and water scarcity for the plant during winter and early spring.
How much water does my Mountain valerian plant require?
To properly water your Mountain valerian, don't be afraid to give it a generous amount of water. Make sure the top couple of inches of soil are dry before watering, and then water thoroughly until the soil is completely soaked. You want to add enough water so that it drains out of the pot's drainage holes. If you don't see any excess water draining, it means you haven't watered enough. However, be careful not to let water accumulate inside the soil, as this can harm the plant. On the other hand, if water is not draining properly, it may indicate that the soil is not draining well, which is not good for the plant. If your Mountain valerian is outdoors, about an inch of rainfall per week should be sufficient.
When is it not a good idea to fertilize my Mountain valerian?
During the late fall and winter, your Mountain valerian will go into a dormant phase and stop producing new growth. It is important to refrain from fertilizing your Mountain valerian at this time. In the spring and summer, if you choose to fertilize, gradually decrease the amount as summer approaches because the growth rate of your Mountain valerian will also slow down. In general, it is not recommended to fertilize your Mountain valerian when the weather is excessively hot or the soil is extremely dry. Fertilizing in such conditions can stress your Mountain valerian and lead to premature death.
What symptoms indicate insufficient or excessive sunlight in Mountain Valerian?
Symptoms of insufficient sunlight in Mountain Valerian include smaller new leaves, leggy or sparse growth, faster leaf drop, slower or no new growth, lighter-colored new leaves, and chlorosis indicating a lack of chlorophyll. Excessive sunlight can cause sunscald, leaf curling as a defense against water loss, wilting due to increased transpiration, and leaf scorching, evident by brown, dry, and crispy leaf edges. These symptoms reflect the plant's struggle to adapt to inadequate or excessive light conditions.
What should be done if mountain valerian experiences temperatures below -30°C?
While mountain valerian is extremely cold-tolerant, winter temperatures should be maintained above -30°C. If temperatures drop below this threshold, there may not be noticeable changes during the winter, but a decrease in sprouting or even no sprouting may occur in spring. In such cases, any parts of the plant that have failed to sprout should be removed in spring.
