Blue Boa, also known as Hummingbird Mint or Hyssop, is native to North America. Agastache has an upright habit of 24-36" with deep violet-blue flowers that bloom from June through September. Blue Boa offers a striking pop of perennial color to borders, landscape beds, or butterfly gardens. Blue Boa excels as a cut flower, and the anise-flavored leaves and flowers have many culinary applications. This plant is deer resistant and drought tolerant once established, bringing bees, hummingbirds, and butterflies to the garden.
Blue Boa Selling Tips
Sell Blue Boa to customers looking for a low-maintenance perennial flower to attract pollinators to the landscape. Homeowners often look for attractive plants to add to borders or cottage gardens without adding to the outdoor workload. Agastache Blue Boa is a perfect choice because of its long bloom season and drought tolerance. Pair this variety in borders or containers with Geranium, Echinacea, and Rudbeckia.
Coach Your Customer:
1. Space plants 16-20" apart in full sun in well-drained soil. Agastache may develop root rot in soils that are too moist. Use gravel at the bottom of your planting hole to provide additional drainage, especially for overwintering.
2. Water regularly, especially during the first year, for a healthy root system.
General Growing Tips For Your Rooted Cutting Liner
To achieve the best results with Blue Boa, plant one rooted plug per 4-inch container. Use a well-drained soil with a pH of 5.5-6.5, EC of 1.5-2.0 mS/cm, and light feed (100-150 ppm). Pinch once at transplant. You may see spider mites or whiteflies. Root rot and downy mildew can be a problem in poorly draining soil or wet conditions.
Flowering
Blue Boa produces fragrant 5-inch tall violet-blue flower clusters June-September. Encourage continuous flowering by cutting spent blooms.
Pinching
Pinching at transplant may benefit growth.
Spacing
Space containers for adequate airflow around the base of each plant and to allow the sun to penetrate to the soil level.
Height Control
This plant doesn't require chemical growth regulators.
Pests
You may see spider mites or whiteflies.
Disease
Agastache is not prone to disease. Avoid root rot by planting in well-drained soil. Watch for rust, which may be indicated by yellowed and withering leaves. Rust should be treated by immediately removing the affected plant parts. For a rust infestation that continues to return, a preventative fungicide may be used when new growth begins in spring. Prevent rust from spreading by removing all diseased debris at the end of the season. Powdery mildew may also affect Agastache, but is unlikely to cause the plant to die. This fungus causes a grayish powder on the surface of leaves, and can be treated by removing affected plant parts and using a preventative fungicide.
Prevent fungus and mildew infection by watering at the base of each plant in the morning, providing adequate airflow in your greenhouse, and allowing sunlight to penetrate to the soil level of each plant.
Planting Blue Boa Liners
We recommend planting one rooted liner per 4-inch container. Use a well-drained soil and completely bury the ellepot in the center of the container.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
