Peach Pearl, also known as Hummingbird Mint or Hyssop, is a hybrid Terra Nova Nurseries developed for large flower spikes and a strong upright habit. This variety also offers mildew resistance and darkened foliage in cooler temperatures. Morello has an upright clumping habit of 27-30" tall and 24" wide. Mint-flavored foliage makes excellent tea, and fragrant burgundy flower spikes bloom from May through September. Peach Pearl brings a striking pop of long-lasting perennial color to containers, borders, and landscape beds. Hardy in zone 5-10, Agastache resists deer, attracts pollinators, and flourishes in full sun with good drainage. For a compact variety, try Poquito Lavender.
Peach Pearl Selling Tips
Sell Peach Pearl to customers looking for a low-maintenance perennial flower to attract pollinators to the landscape. Homeowners often look for attractive perennials for borders or cottage gardens that won't add to the outdoor workload. Morello offers many benefits, including mildew tolerance, a pleasant aroma, culinary use, and a long bloom season. Bees and butterflies love Agastache. This plant is well-suited to mass plantings or pairs well in borders or large containers with Panicum, Perovskia, Leucanthemum, Rudbeckia, and Echinacea.
Coach Your Customer:
1. Space plants 18-24" 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 flowers back in late summer to encourage continued blooming.
General Growing Tips For Your Rooted Cutting Liner
To achieve the best results with Peach Pearl, 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.
Flowering
Burgundy flower spikes bloom from May through September.
Pinching
Pinch once at transplant.
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 PGRs.
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 Peach Pearl 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.
