Kudos Silver Blue, also known as Hummingbird Mint or Hyssop, is a hybrid Terra Nova Nurseries developed as a genetically dwarfed Agastache with no need for growth regulators. This variety is also super-hardy and extremely downy mildew resistant. Kudos offers an upright bushy habit of 20-27" tall and 12-24" wide. Honey-mint scented light blue flower spikes bloom from June through September. Kudos Silver Blue brings a striking pop of long-lasting perennial color to containers, borders, and landscape beds. Hardy in zone 5-10, Agastache is deer resistant and attracts bees and butterflies. For color variety, grow Silver-Blue alongside Mandarin.

Coach Your Customer:
1. Space plants 18" 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.
3. Cut back to 3-4" tall in spring.
General Growing Tips For Your Rooted Cutting Liner
To achieve the best results with Kudos Silver Blue, 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. This variety offers superior disease resistance.

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 Kudos Silver Blue 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.
