The Agastache 'Blue Boa' is a hardy perennial for garden enthusiasts seeking vibrant, long-lasting color and pollinator attraction with minimal effort. Its key benefit is the striking tall spikes of purple flowers that bloom from mid-summer to autumn, complemented by aromatic foliage. A caveat to note is that live plants may vary in appearance from images and can be pruned seasonally.

The best time to plant is in spring after the last frost, or in early autumn, allowing the plant time to establish its roots before extreme weather conditions.
Water regularly until established. Once settled, it is drought-tolerant, so water only when the top inch of soil feels dry. Avoid waterlogged conditions.
Yes, Agastache 'Blue Boa' is a hardy perennial and is expected to survive winter. Cut back the dead foliage in late autumn or early spring.
The aromatic oils are best released when the leaves are crushed or bruised. Gently rub a leaf between your fingers to release the scent.
This is a common practice to encourage bushier growth and a more compact form. The plant will readily produce new shoots from the base.
Agastache 'Blue Boa' typically grows to be quite tall, producing spikes that rise above the foliage, often reaching heights suitable for borders and dramatic displays.
While it can be grown in containers on a patio or balcony, Agastache 'Blue Boa' is best suited for outdoor garden conditions as it requires full sun and good air circulation.
Ensure the plant is receiving at least 6-8 hours of direct sunlight per day. If the plant is overcrowded, thin it out. Deadhead spent blooms regularly to encourage further flowering.
This can indicate overwatering or poor drainage. Check soil moisture and ensure the plant is in well-drained soil. Allow soil to dry slightly between waterings.
Inspect plants regularly. Aphids can often be washed off with a strong jet of water or treated with insecticidal soap. Encourage natural predators by planting a diverse range of plants.
Check if the soil is too dry, especially during hot weather, and water thoroughly. If the soil is waterlogged, ensure better drainage is provided.
Planting: Select a location that receives full sun. Ensure the soil is well-drained; amend heavy clay soils with grit or compost to improve drainage. Dig a hole large enough to accommodate the root ball and plant the Agastache at the same depth it was in its grower's pot. Water thoroughly after planting.
Watering: Water regularly until the plant is established. Once settled, 'Blue Boa' is quite drought-tolerant and requires minimal watering, especially in regions with adequate rainfall. Avoid overwatering, as this can lead to root rot.
Soil: Prefers well-drained, fertile soil. It can tolerate poorer soils but thrives with good drainage.
Feeding: Generally, this plant does not require heavy feeding. A light application of a balanced, slow-release fertilizer in spring can be beneficial.
Pruning: To encourage more blooms, deadhead spent flower spikes by cutting them back to a set of leaves. In late autumn or early spring, cut the plant back to the ground or to about 6 inches to maintain a compact shape and encourage vigorous new growth.
Compatibility: This plant is suitable for mixed borders, rock gardens, cottage gardens, and container planting. It pairs well with other sun-loving perennials and ornamental grasses.
