Summerlong™ Peach Agastache (Agastache mexicana ‘Balsumleac’) shines with trumpet-shaped blooms in a soft peach hue, drawing attention all season long. This sun-loving perennial stays compact at about 16 to 22 inches tall and wide, making it perfect for patio planters or tight spaces in the garden. Its delicate flowers carry hints of rose and are held on sturdy upright stems that pollinators can’t resist. Hummingbirds, bees, and other beneficial visitors arrive in droves, while deer usually bypass it, allowing you to enjoy the show in peace. The blooms arrive earlier than other Agastache varieties, adding an extended burst of summer color.
Summerlong™ Peach Agastache's fragrant green foliage adds an extra layer of appeal, blending scent with summer color. Native to regions with warm, sunny conditions, it handles heat and drought once it’s established. The neat, dense habit suits containers, borders, and group plantings. Birds and butterflies find the abundant nectar irresistible, making this perennial a valuable addition to eco-friendly gardens. Its compact size saves on trimming time and results in a fuss-free, low-maintenance display.
Summerlong™ Peach Agastache Care
Plant Summerlong™ Peach Agastache in a spot that receives at least six hours of direct sunlight per day, and select soil with good drainage to prevent root rot. Water thoroughly during the first several weeks, then reduce the frequency once roots have settled. Occasional feeding with a light, balanced fertilizer can boost its floral performance, though over-fertilizing might lead to weaker stems. A slightly acidic to neutral soil pH works well, and mulch around the base can help keep moisture levels steady. In containers, ensure you use a potting mix that drains quickly, especially in rainy climates.
Snip off spent blooms (deadheading) when the flowers begin to fade, encouraging new waves of color. If stems grow spindly, consider pinching back or lightly trimming to promote a fuller shape. Removing old foliage in early spring helps the plant concentrate its energy on fresh shoots. Summerlong™ Peach Agastache can live in containers year-round in zones 7 to 10. If you experience harsh winters, shelter potted specimens in a protected area.
Summerlong™ Peach Agastache Spacing
Leave about 14-16 inches between plants for a mass planting, allowing airflow for healthy growth. A container measuring 12 to 14 inches in diameter works well for one plant, offering adequate room for roots and avoiding overcrowding. Larger pots are fine if you wish to include companion plants, but be sure each variety has the space it needs to thrive.
