Summerlong™ Coral Agastache (Agastache mexicana) lights up your garden from late spring through summer with its bright salmon-pink flower clusters. Its upright, mounded habit reaches about 16 to 22 inches tall and wide, making it a lovely accent in mixed borders or patio containers. These tubular blooms draw in hummingbirds and bees, adding lively movement to your outdoor space. The compact, aromatic foliage fits nicely in various garden styles, and its reliable performance in summer heat gives you a fuss-free, eye-catching display. Gardeners love this plant for its pollinator-friendly qualities and show-stopping color that lasts for weeks.
In addition to the wonderful flower show, Summerlong™ Coral Agastache offers fragrant foliage and a tidy growth habit. Native to parts of Mexico, it handles dry conditions after it’s established and thrives in full sun, helping it flourish even in hot climates. Deer generally avoid it, so you can admire its blooms without worry. Use it as a cheerful, upright companion in perennial beds, or plant in groups for mass color. The flowers also work well as cut stems for smaller bouquets.
Summerlong™ Coral Agastache Care
Plant this Agastache in a site that receives at least six hours of direct sun daily for optimal flower production. Well-drained soil is key, so avoid overly wet areas or heavy clay that holds moisture. Water moderately after transplanting and gradually reduce watering once the plant settles in, as it tolerates drier soils and summer heat quite well. A light application of a balanced fertilizer in early spring can support healthy growth, but excessive feeding may reduce flowering. During peak summer, keep an eye on soil moisture, especially if you’re growing it in pots, since container plants can dry more quickly.
When it comes to pruning, a gentle clip or deadheading will encourage extended blooming. Removing faded flower spikes helps maintain a neat appearance and promotes fresh blooms. If additional shaping is needed, trim lightly, but avoid severe cutting back during extreme heat. For container culture, remove spent blooms regularly, and consider repositioning your potted plant to a slightly shadier spot if it shows stress from intense sun.
Summerlong™ Coral Agastache Spacing
Space individual plants about 16 inches apart if you’re creating a summer-flowering border or grouping. This ensures enough room for root expansion and sufficient air circulation. When growing in containers, select pots that are at least 10 to 12 inches wide, allowing this free-blooming beauty plenty of space to flourish.

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
