Description

Aconitum arendsii, commonly known as Arends’ Monkshood, is a perennial plant that belongs to the Ranunculaceae (Buttercup) family. It is native to the mountainous regions of Central and Eastern Europe and is known for its tall spikes of blue-purple flowers. It is a hardy plant and can tolerate cold temperatures and poor soil conditions. 

Which soil to use?

Aconitum arendsii prefers well-drained, moist soils that are rich in organic matter. The soil should have a neutral pH (around 7.0) and be able to retain moisture while still allowing for good drainage. A humus-rich soil that is slightly acidic to neutral would be ideal. If your soil is heavy clay or sandy, you may need to amend it with organic matter like compost or well-rotted manure to improve its structure and water-holding capacity. Additionally, it grows in partial shade, so it’s important to have a good exposure to sunlight to grow this plant.

Best location for this plant?

The plant prefers cool, moist growing conditions and can tolerate temperatures as low as -30°F. It can be planted in a shaded border, woodland garden or along a stream or pond.

It is also a great option for a naturalized area or a wildflower garden, as it will attract pollinators like bees and butterflies. If you are planting it in a garden setting, it is best to give it some space, as it can grow up to 4 feet tall and 2 feet wide. If you are planting multiple plants, space them about 2-3 feet apart. Avoid planting it in full sun, as the foliage may become scorched, and it may not bloom as well.

Pests and diseases to look out for?

Aconitum arendsii is generally resistant to many pests and diseases. However, there are a few things to look out for:

  • Slugs and snails: These pests can damage the foliage and flowers of Aconitum arendsii. You can control them by using slug bait or by handpicking them from the plants.
  • Aphids: These small insects can suck the sap from the plant, causing the leaves to yellow and curl. You can control them by blasting them off with a strong jet of water or by using an insecticidal soap.
  • Powdery mildew: This fungal disease can cause a white powdery coating on the leaves, which can eventually lead to leaf yellowing and defoliation. It can be controlled by applying a fungicide or by providing good air circulation around the plant.
  • Root rot: This disease can occur if the soil is too wet or poorly drained. It can cause the plant to wilt, yellow, and eventually die. To prevent root rot, make sure the soil is well-drained and avoid over watering.

It’s also worth noting that all parts of the plant are poisonous if ingested and the sap can cause skin irritation, so handle with care and wash your hands after handling.

How to propagate?

There are several methods to propagate Aconitum arendsii:

  1. Root division: This is the easiest and most common method of propagation. In late summer or early autumn, carefully dig up the clump and divide it into smaller sections, making sure each section has at least one healthy bud or “eye”. Replant the divisions immediately and water well.
  2. Seed propagation: Collect the seeds from the plant when they are ripe in late summer or early fall. Sow the seeds in a cold frame or unheated greenhouse in the autumn, or in early spring. Germination can be slow, it can take up to 2-3 weeks.
  3. Stem cuttings: Take stem cuttings from the current season’s growth in the summer. Remove the leaves from the lower half of the cutting and dip the cut end in rooting hormone powder. Place the cuttings in a pot filled with moist sand or perlite, and cover with a plastic bag to create a humid environment. Keep the cuttings in a shaded area and wait for roots to form, which can take several weeks.
