Hosta sieboldiana aka Blue Angel Hosta

Taxonomy

Hosta sieboldiana, also known as Siebold's plantain lily, is a popular species of hosta native to Japan. It is a large, clump-forming, herbaceous perennial with broad, ovate, and blue-green foliage that has prominent veining and a wavy edge. During the summer, it produces white, bell-shaped flowers on stems that can reach up to 80cm in height. This variety of hosta, specifically Hosta sieboldiana var. elegans, has been awarded the Royal Horticultural Society's Award of Garden Merit, as has a variety of its synonym, Hosta fortunei var. aureomarginata, known as the gold-edged plantain lily. Additionally, the cultivars 'Blue Angel', 'Blue Mammoth', and 'Olive Bailey Langdon' have also received the RHS Award of Garden Merit. While hostas are favored for shady areas, this particular hosta is considered a garden classic due to its large, powdery-blue, heart-shaped leaves. It is known to be slightly less palatable to deer, although they may still enjoy eating it. Hosta sieboldiana can be easily divided in either spring or fall, and the dying foliage can be removed before mid-spring. It is a resilient plant with good slug resistance and can be left undisturbed for years.

Blue Angel Hosta, Bressingham Blue, Siebolds Hosta

How to care for Blue Angel Hosta

Difficulty

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

Water

Blue Angel Hosta should be watered regularly, allowing the soil to dry out between waterings.

Soil

Blue Angel Hosta 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 Blue Angel Hosta 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 Blue Angel Hosta to go dormant, resulting in a slowdown of growth. To accommodate this, waterings should be spaced out more.

Toxicity

Ploi lacks confirmed information on the toxicity of this plant. If you, a relative, or your pet accidentally consume plant material with unknown toxicity, it's best to consult a medical expert.

Humidity

The Blue Angel Hosta does not need extra humidity. Plants primarily absorb water through their root system, making soil watering the best way to provide humidity to your plants.

Fertilizer

The Blue Angel Hosta should be repotted when it has doubled in size or annually, whichever comes first. Providing fresh potting soil with all the essential nutrients each year ensures the plant's well-being, eliminating the need for fertilizer. Remember, plants derive their energy from the sun and not fertilizer.

Region of origin
