Eupatorium cannabinum aka Hemp Agrimony

Taxonomy

Eupatorium cannabinum, also known as hemp-agrimony or holy rope, is a robust perennial herbaceous plant of the Asteraceae family. It is native to Europe, as well as NW. Africa, Turkey, Syria, Iran, Iraq, Jordan, the Caucasus, and Central Asia. While it is occasionally found as a garden escape in the United States, Canada, and China, it is primarily cultivated for ornamental purposes. With racemes of mauve flower heads that bloom from July to early September, this dioecious plant is pollinated by insects and is attractive to butterflies, much like buddleia. The flower heads are tiny, fluffy and can range from pale dusty pink to whitish. It can be invasive in forest habitats. Hemp-agrimony prefers moist low-lying areas and well-draining soil. As a rare houseplant, it requires regular watering and direct light, and should be less than 1 foot from a window. Supplementing with gentle, organic fertilizer throughout the peak growing season can be beneficial.

How to care for Hemp Agrimony

Difficulty

If you're looking for a plant that offers a moderate level of challenge, Hemp Agrimony is a great choice to test your gardening skills.

Water

Hemp Agrimony should be watered regularly, allowing the soil to dry out between waterings.

Soil

Hemp Agrimony loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

To ensure optimal growth, the Hemp Agrimony prefers bright indirect light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

Dormancy

During the cold period, it is common for Hemp Agrimony to go dormant, resulting in a slowdown of growth. To accommodate this, waterings should be spaced out more.
