Hot pink to magenta hued blooms on bright green, medium tall square stems with lance-shaped toothed leaves describes Agastache Rosie Posie to a ‘T’. A member of the mint family, this fragrant leafed plant will be a favorite in a children’s garden, pollinator garden or your informal cottage gardens. Tall flower spikes sway in the wind like wheat, creating movement in the sea of green and pink. Pair these lovely perennials with coreopsis, yarrow and rosemary for a lively colored, scented garden.

Native to North America, Agastache finds its home in prairie lands, meadows and higher elevation forest lands and fields. It is often found in rocky soils and makes a beautiful addition to a rock garden in your landscape. Hardy in Zones 6-9, it thrives in full sun and humidity. It has a sweet anise scent when you brush the leaves, although the flowers have no scent. Once established in your garden it is an easy to care for perennial that will eventually spread out and fill in any space you want to assign it to.

Rosie Posie Anise Hyssop Care

Plant your agastache in full sun for best flowering performance. It can take the heat and will continue to bloom in summer until early fall even in the hottest sun regions. Well draining soil is a must. Its native habitat is typically rocky soil which drains extremely fast. It does require regular watering, though, so water deeply at the root level when the top inch of soil is dry. Avoid wetting the leaves any more than you have to to discourage any fungal diseases. Typical soil pH is 6.0 to 8.0, slightly acidic to slightly alkaline, so you have a lot of latitude there. Give an application of a well balanced slow release, low nitrogen fertilizer, like a 10-10-10, to encourage lush growth without the sacrifice of flowers.

Deadheading is encouraged to extend bloom time and keep plants from going to seed. Seeds in hybrid varieties rarely produce true, so rely on dividing the roots every three years or so for best division of plants. These vigorous plants grow on rhizomes that can spread throughout your garden bed once they are fully established, so root ball division is not only a great way to get more plants, it is a necessity to prevent them from taking over your garden. Cut plants down by half at the end of the season to allow new growth in the spring room to grow. It will not hurt the plant and will help keep things looking tidy for you.

Rosie Posie Anise Hyssop Spacing

For best performance and reduction in plant fungal disease, space your agastache at least 24 to 30 inches apart from other plants. At maturity they can reach 22 inches tall and spread out 30 inches wide. Use a good pine mulch on the root zone of the plant for overwintering protection. Keep mulch back from the stems a bit to prevent crown rot. With care you will enjoy these beautiful hot pink flowers year after year.
