Monkshood Features: An Overview
- Monkshood is a herbaceous perennial flowering plant. Depending on the cultivar, this plant can reach from 2 to 4 feet (60-120 cm) in height and 1 to 2 feet (30-60 cm) in width. In optimum conditions, the plant may grow as tall as 5 feet (150 cm).
- Its foliage consists of numerous small, leathery, palmate to deeply palmate and lobed, toothed, and green leaves that appear in spirals on long, upright, rigid, and green-brownish stems. The leaves lack stipules and the lower ones feature long petioles.
- Monkshood blooms throughout the summer months. During this season, it produces racemes of large purple, blue, white, pink, yellow, greenish, red, or greyish flowers on tall, erect, wood-like, and green to brown stems.
- The blossoms of this plant have many stamens and one of the five petaloid sepals in the form of a cylindrical helmet called galea. They can exhibit two to ten petals. While the upper petals are pretty large, the other ones are usually smaller.
- Once its flowering period has ended, Monkshood bears fruits where the blooms were. The fruits are aggregates of follicles, where each follicle is a dry structure that contains many seeds.
Growing Monkshood
In terms of lighting, Monkshood can grow very well in a wide variety of conditions. This plant will handle both full sunlight and partial shade. As a rule, the more direct light Monkshood receives, the better the blooming will be. If you live in a warmer region, however, you might want to grow this plant in a partially shaded location. The harsh summer or afternoon sunlight is not so good for Monkshood because it will burn its delicate petals with time.
One interesting fact about Monkshood is that it is not as fragile as it might appear. This flower is winter-hardy in the USDA zones 3 through 7. Moreover, since the plant comes from mountainous areas, it actually prefers weather that is more on the cooler side. Monkshood will not appreciate hot temperatures or high humidity levels. Keep in mind that the amount of shade this plant will need usually depends directly on how warm the weather is.

Monkshood is virtually pest-free, but we cannot say the same when it comes to fungal diseases. When this plant goes through a stressful period, it may become prone to various diseases like bacterial leaf blight, powdery mildew, crown rot, or verticillium wilt. These fungal diseases appear due to poor drainage overall and extreme humidity or heat.
If you want to prevent these issues from happening, make sure you are growing your Monkshood in proper environmental conditions. In case you already fight with an infection, remove the unhealthy parts from your plant, then treat it with a suitable fungicide.
Planting Monkshood
In general, Monkshood grows at its best in moist soils that are also rich in organic matter and nutrients. But! Due to its innate love for moisture, the plant easily becomes susceptible to root rot. We warmly recommend planting your Monkshood in soil that comes with very sharp drainage overall. Although this plant prefers neutral to slightly acidic substrates, it will tolerate any other type of soil as long as it is well-draining.
The frequency of fertilizing will vary depending on the quality of the growing medium. The richer the soil is, the fewer applications of fertilizers your Monkshood will need. For optimal results, try to find the perfect high-in-organic-matter soil for your beloved plant. After this step, provide your Monkshood with compost and an organic fertilizer once every year in spring.
Since Monkshood is a late-season bloomer and does not bloom repeatedly, you can forget about deadheading for good. Likewise, once the frost shows its presence, the plant will naturally die back. The only time when you should intervene is if your Monkshood becomes somewhat leggy or too tall for your taste. When this happens, you can trim some of its foliage off to bring the plant to the desired length and shape.
Watering Monkshood
As mentioned above, Monkshood is a fairly thirsty plant in general. This moisture-loving flower will require more attention than other ordinary plants. On the other hand, constant soggy conditions or waterlogging may cause serious fungal problems that are usually irreversible. We know, this might seem a bit overwhelming, especially if you are at the beginning of the road. But do not get discouraged!
Monkshood needs frequent watering only during its active growing period, typically in spring. In this season, you will have to spoil your plant with a nice drink whenever the top half of the soil feels dry to the touch. You can check the soil’s moisture using a finger or a moisture meter.
In the remaining seasons, Monkshood will do just fine if you water it only when its growing medium has dried out completely. Once established, this plant can also tolerate drought for short periods. Although it is not a tragedy if it happens to forget about watering your plant, keep in mind that it does best with regular moisture.

Propagating Monkshood
Have you fallen in love with Monkshood so much that you want to share it with some of your family members and friends? Or, maybe, you want more of these beauties just for yourself? Either way, you can make more Monkshood plants without spending extra money by propagating yours through seeds or division. These methods require no special experience in the gardening world, so you can get to work right away!
It is important to mention that starting your Monkshood from seed can be pretty tricky. In general, it is possible for some seeds not to sprout or to take more than a year to do so. Because of this, we suggest you collect and sow as many seeds as possible to increase your chances of success.
The seeds need to go through a chilling period to germinate, so make sure you sow them directly outdoors in late autumn. If some of the baby Monkshood plants are for your beloved ones, you can sow the seeds in pots. For great results, water the seeds once every week or so.
If you want to propagate your Monkshood through division, you will have to wait for your plant to become mature and well-established. Once the plant is about three years old, you can dig it out from the soil to divide its roots. Section the roots into two or three parts, replant each section in its permanent spot, then water them well to help them settle in their new home.
Because this plant does not enjoy transplanting, it may take a while to re-establish. The division is also a great method to keep your plant vigorous.
In Conclusion
Now that you know more about growing Monkshood, you won’t have any trouble filling your garden with these beautiful flowers. The next step is to find out which cultivars meet all your secret expectations from a garden plant. No pressure, though! But once you decide, make sure you come back and share your pick with us!
