The Royal Raspberry Agastache, also known as Agastache aurantiaca ‘Royal Raspberry’, is a stunning tall native perennial that can add a vibrant touch to any garden or landscape. It belongs to the mint family and is native to North America.
One important aspect to consider when growing any plant is its hardiness and the specific climate conditions it can tolerate. The Royal Raspberry Agastache is generally hardy in zones 5-9. This means that it can withstand cold temperatures down to -20°F (-28°C) in zone 5, and still thrive in the warmer climates of zones 6-9.
To determine the specific hardiness zone of your location, you can refer to the USDA Hardiness Zone Map. This map divides the United States into different zones based on average annual minimum temperatures. By finding your location on the map, you can identify which zone you are in and whether it falls within the recommended range for growing the Royal Raspberry Agastache.
In my personal experience, I have grown the Royal Raspberry Agastache in zone 7, and it has flourished beautifully. The plant has a compact habit, growing up to 32 inches wide, and its tall stems can reach heights of 28-32 inches. This makes it an excellent choice for adding vertical interest to your garden.
The Royal Raspberry Agastache is also known for its striking raspberry-colored flowers, which attract pollinators such as bees, butterflies, and hummingbirds. These flowers appear in dense spikes and provide a long-lasting display of color throughout the summer and into the fall.
In terms of care, the Royal Raspberry Agastache prefers full sun to partial shade and well-drained soil. It is relatively drought tolerant once established, making it a low-maintenance choice for gardeners. However, regular watering during dry periods can help promote healthy growth and flowering.
The Royal Raspberry Agastache is hardy in zones 5-9, making it suitable for a wide range of climates. Its tall stature, vibrant raspberry-colored flowers, and ability to attract pollinators make it a valuable addition to any garden or landscape. Whether you live in a cooler zone 5 or a warmer zone 9, this native perennial can thrive and bring beauty to your outdoor space.
