Korean angelica Angelica gigas
ABOUT
Angelica gigas, commonly known as Korean angelica, is a robust perennial plant that presents a striking and imposing appearance in gardens and natural settings. The plant displays a thick, purplish, hollow stem that is upright and branched, giving it a strong architectural look. At the top of these stems, Korean angelica produces large, spherical umbels of small flowers that can be a deep, rich purple or reddish-purple hue. These showy flower clusters make the plant a favorite among gardeners looking for dramatic color and structure. Its foliage is equally attractive, consisting of large, pinnate leaves that are divided into smaller leaflets. The leaves are green, often with a hint of purple running through the veins, adding to the plant's overall lush and vibrant appearance. The edges of the leaves are serrated, providing a textured effect. The presence of these leaves complements the flowers, creating a contrasting backdrop that enhances the visual impact of the blooming umbels. Korean angelica adds to its appeal with a unique aromatic quality. The scent of the leaves and stems when crushed is notable and adds another layer of interest to this plant. Its impressive presence and the deep, rich colors it brings to the landscape make it a sought-after species for gardeners looking to add both height and drama to their plantings without delving into specific dimensions.

WaterKorean angelica should be watered deeply once a week, providing enough water to soak the root area. Aim to provide about 1 inch of water, which roughly translates to 0.6 gallons for an average-sized plant. During the hotter seasons or in particularly dry climates, you might need to water more frequently, ensuring the soil remains moist but not waterlogged. Adjust the watering schedule during the rainy season or cooler months, reducing the frequency to prevent overwatering. Always check the soil moisture level before watering to avoid excessive moisture, as this can lead to root rot.
LightKorean angelica prefers full sun to partial shade conditions. It thrives best when receiving at least 6 hours of direct sunlight daily, though it can tolerate some afternoon shade, especially in hotter climates. Planting Korean angelica in a spot where it's protected from the intense midday sun can help prevent leaf scorch.
TemperatureKorean angelica grows well in a temperature range between 60°F to 75°F, which are considered the ideal conditions for this plant. It can withstand minimum temperatures down to about 5°F, but for proper growth and development, it should not be exposed to extreme cold. Be mindful of sudden temperature drops and frosts, as they can damage the plant.
PruningPruning Korean angelica is necessary to remove spent flowers and encourage new growth. Prune in late fall or early spring before new growth begins. Remove any dead or damaged stems to maintain plant health and improve air circulation. Pruning can be done annually, or as needed, to shape the plant and manage its size.
CleaningAs needed
SoilKorean Angelica prefers a well-draining soil mix rich in organic matter. An ideal mix might consist of equal parts loam, peat, and sharp sand, helping to ensure adequate drainage yet retaining enough moisture for the plant's needs. The soil pH should be slightly acidic to neutral, ranging from 6.0 to 7.0 for optimal growth conditions.
RepottingKorean Angelica does not typically require frequent repotting as it can be grown as an annual or biennial. When grown as a perennial, it can be repotted or divided every few years to refresh the soil and accommodate growth. Overwinter indoors, and it's suggested to repot in the spring if necessary.
Humidity & MistingKorean Angelica thrives in an environment with moderate humidity levels. It does not require the high humidity levels that some tropical plants do but will appreciate not being placed in an overly dry location. Average room humidity should suffice, but if the air is particularly dry, occasional misting may benefit the plant.
Suitable locationsIndoor
Provide bright indirect light, keep soil moist, and ensure good air circulation.
Outdoor
Plant in partial shade, in well-draining soil, and water regularly.
Hardiness zone
4-9 USDA.
Life cycleAngelica gigas, also known as Korean angelica, begins its life as a seed, which requires a period of cold stratification to break dormancy and germinate successfully. After stratification, germination typically occurs in the spring, growing into a rosette of leaves in its first year of life, remaining in this vegetative state without flowering. In its second year, the plant transitions from the rosette stage to bolting, wherein a flowering stalk elongates, and the plant develops umbel-shaped clusters of purplish or reddish flowers. Following pollination, typically by insects, Angelica gigas produces schizocarpic fruits that split into two, dispersing seeds for the next generation. The plant is monocarpic, meaning it usually dies after setting seed, completing its life cycle. However, if flowers are removed before seed set, the lifespan may extend over several years, with the plant reverting to a vegetative state and possibly flowering again in successive years.
PropogationPropogation time
Late summer
Propogation: Korean angelica, commonly referred to as Angelica gigas, is primarily propagated by seed. The best time to sow the seeds is in late winter or early spring as this aligns with their natural germination cycle. For successful propagation, seeds need to be fresh because their viability decreases significantly with age. A preferred method involves surface sowing the seeds onto a well-draining seed starting mix, as they require light to germinate. The flats should then be placed in a cold frame or unheated greenhouse. Germination can be irregular, taking anywhere from 30 to 120 days. It's important to keep the soil consistently moist but not waterlogged throughout this period. Once the seedlings have emerged and are large enough to handle, they can be transplanted into individual containers before eventually being moved to their final position in the garden.
