What Are the Characteristics of Aconite?

Aconite is a perennial herbaceous plant, with a simple annual stem, which can measure 5 ft (1.5 meters) in height. It has a turnip-shaped root, which dies at the end of fruiting. However, the plant survived due to adventitious roots sprouting from the stem.

Aconite leaves are alternate, palm-shaped, divided into long strips of irregular shape, called laciniae. They are bright green, rigid and flexible, with a leathery appearance.

On the other hand, its flowers are zygomorphic, composed of 5 different pieces of deep blue or dark violet color. They bloom from July to October and reach 1.2″ to 1.6″ (3 to 4 centimeters) in diameter and 0.8″ (2 centimeters) high.

They are grouped in clusters at the top of the stem. The fruit of the aconite measures approximately 0.66″ (17 millimeters) and is made up of 3 to 5 arched follicles. Each follicle contains numerous black, pyramidal, and shiny seeds of small size, between 0.11″ and 0.2″ (3 and 5 millimeters).

When to Plant Aconite?

Aconite is a cold and frost-resistant plant. It can be multiplied by seed, indoors, during the months of January, February, and March.

In the case of outdoor sowing, it should be done in January, August, September, or December.

It can also be grown through the roots of the plant during the months of September, October and November, in order to see them bloom during June, July, and August.

It can be planted by bulb during the spring, but the level of moisture in the soil should be monitored, especially during the first summer.

Where to Plant Aconite?

The aconite plant should be planted in a place where it can benefit from direct sunlight, or in a semi-shade. It needs a moist, deep, and nitrified substrate.

If you want to plant it in warm regions, you should look for an area with a semi-shade, where it is exposed to sunlight only for a few hours in the morning or in the evening.

How to Grow Aconite by Seed

  1. Place seeds in a container or plastic bag with moist sand, preferably mature seeds due to their long dormancy and low germination rate.
  2. Place the container in a humid and warm environment, between 60 °F and 71.6 °F (16°C and 22°C), for a period of 2 to 4 weeks.
  3. Move the container to a cold place, preferably in the refrigerator, at temperatures between 24 °F and 41 °F (-4°C and 5°C), for a period of 5 to 6 weeks.
  4. After the recommended time, remove the container from the cold and keep it at room temperature, checking regularly to see if any seeds have germinated.
  5. Once the seedling has grown sufficiently, place it in a hole twice its size and enrich the area with organic fertilizer.
  6. Water abundantly without saturating the substrate.

How to Grow Aconite by Root Division

  1. Divide the extracted root of the aconite into 2″ (5-centimeter) sections along with part of its root system.
  2. Transplant the roots to the desired area, in holes slightly larger than the plant segment, 2″ (5 centimeters) deep, leaving a separation of 2″ to 4″ (5 to 10 centimeters) between them.
  3. Water the area to compact the substrate.
  4. This process can be done every 4 to 5 years during the fall, when flowering decreases.
