Angelica
Angelica archangelica, commonly known as wild celery or garden angelica, is an umbelliferous biennial plant of the Apiaceae family. Native to areas in the northern and southern hemispheres, Angelica archangelica and its relatives are an excellent addition to any garden. Its attractive foliage and tall, fragrant inflorescences can reach up to 6 feet tall. The leaves and stems of the plant are edible and it is often used as a flavoring in cooking and alcohol beverages. When planted indoors, it can easily reach a height of 3 to 4 feet and is an elegant, fragrant addition to the living room or kitchen.
Angelica archangelica prefers moist soil and should be watered regularly, especially during hot periods. Water when the soil is dry to the touch, usually when the top inch of soil is dry. Do not over water, as this can lead to root rot and other issues. During the winter, water less. Never let the soil dry out completely, as this can lead to death of the plant.
Angelica archangelica prefers full sun, however, it can also grow in partial shade. If grown in full sun, give young plants plenty of protection from the hot midday sun in the summer. It is best suited for climates with moderate temperatures and average levels of humidity.
Angelica archangelica thrives in temperatures ranging from 45°F (7°C) to 75°F (25°C). High temperatures may cause the plant to go into dormancy, thus it is best to limit exposure to temperatures above 85°F (30°C). Frost may cause the plant to die, so make sure to protect from cold winter temperatures.
High levels of humidity will not hurt Angelica archangelica, however, dry air may cause the tips of the leaves to dry out. If the humidity levels are low, mist the leaves regularly in order to keep them hydrated.
Angelica archangelica prefers well-draining soil. It is best to use a mix of one part peat moss and two parts of perlite, vermiculite or both. Alternatively, you can use a potting mix made for herbs or vegetables.
As a biennial plant, Angelica archangelica will likely only need to be fertilized during its first year of growth. During the growing season, use a balanced, all-purpose liquid fertilizer about every two weeks. In its second year, fertilization is not necessary. When fertilizing, make sure to follow the instructions on the label as overfertilizing can burn the roots of the plant.
Angelica archangelica is relatively resistant to pests. Common pests that might affect the plant include Aphids, mealybugs, spider mites and thrips. To get rid of the pests, gently spray the plants with lukewarm water. If that doesn’t do the job, spray the plant with a mixture of 1 teaspoon of dish soap and 1 teaspoon of baking soda mixed with 4 cups of water. The mixture should be sprayed directly onto the pests, making sure to coat both the top and bottom of the plant. For heavier infestations, you may need to use an insecticide. Make sure the insecticide is safe to use on edible plants.
Angelica archangelica does not require frequent repotting. It typically only needs to be repotted every three to five years. During repotting, replace the old soil with fresh, well-draining potting soil and make sure to use a pot that is just large enough to accommodate the root system. Make sure to not leave the plant in the same spot for too long, as this may cause the soil to become depleted of nutrients.
Pruning is not necessary, but it can help promote healthy growth of the plant. To encourage bushier growth, remove the flowers and the top part of the stem as soon as possible. If the stems get too long, trim them back to keep them in check. Make sure to use sharp pruning shears for a clean cut.
The plant can benefit from mulching in the wintertime. Use organic matter such as compost or straw to cover the soil to protect the roots from the cold. Make sure to remove the mulch in the early spring to prevent the soil from becoming waterlogged.
Angelica archangelica can be propagated from seed or cuttings. To propagate the plant from seed, lightly cover the seeds with soil and lightly water. It takes about 3 weeks for the seeds to germinate. Alternatively, you can take stem cuttings and place them in a pot filled with a mixture of peat moss and perlite. Keep the cuttings in a bright location and lightly water them.
Angelica archangelica does not require support, however, you may need to stake the plant if it is left outdoors during heavy winds.
Angelica archangelica does not require a rest period. In fact, the plant will benefit from having its foliage trimmed or pruned during the winter months to promote better growth.
Angelica archangelica is not a toxic plant, and it is safe to have around pets. However, it is best to keep the plant away from animals as some parts of the plant can be indigestible.
