  5. Mulch the soil: Applying a layer of organic mulch around the base of the plant can help conserve moisture, regulate soil temperature, and suppress weed growth. Use a 2-3 inch layer of mulch, keeping it a few inches away from the plant’s stem to prevent rot.
  6. Divide overcrowded plants: Agastache rupestris can become overcrowded over time, leading to reduced blooming. To rejuvenate the plant and promote more blooms, divide it every 3-4 years in early spring or fall. Dig up the clump, separate the healthy sections, and replant them in well-prepared soil.


To successfully grow and care for agastache rupestris, also known as peachie keen or rosie posie, it’s important to follow proper plant care techniques. By pruning, propagating, and growing from seed, you can ensure the health and longevity of your plants. Let’s explore some practical advice on how to care for agastache rupestris.

Pruning is an essential part of agastache rupestris care. It helps maintain the plant’s shape, promotes healthy growth, and prevents overcrowding. To prune your agastache rupestris, use clean, sharp pruning shears and remove any dead or damaged branches. Additionally, you can prune the plant in early spring to encourage new growth and maintain a compact form.

Propagation is another method to expand your agastache rupestris collection. You can propagate this plant by taking stem cuttings or dividing the root ball. When taking stem cuttings, choose healthy stems and remove the lower leaves.

Dip the cut end in a rooting hormone and place it in a well-draining potting mix. Keep the soil consistently moist until roots develop. When dividing the root ball, gently separate the plant into smaller clumps and replant them in suitable locations.

If you want to start agastache rupestris from seed, it’s best to sow them indoors before the last frost date. Fill seed trays with a well-draining seed starting mix and lightly press the seeds into the soil. Keep the trays in a warm location with indirect sunlight and water gently.

Once the seedlings have developed a few true leaves, you can transplant them into individual containers or directly into the garden.

Understanding the blooming season of agastache rupestris is crucial for maximizing its beauty in your garden. Typically, these plants bloom from summer to fall, producing vibrant spikes of flowers.

To encourage blooms, provide your agastache rupestris with full sun exposure and well-draining soil. Regular watering and occasional fertilization can also help promote healthy flowering.

Keep an eye out for common pests and diseases that may affect your agastache rupestris. Aphids, spider mites, and powdery mildew are potential problems.

If you notice any signs of pest infestation or disease, promptly treat them using organic pest control methods or appropriate fungicides. Regular inspection and early intervention can help keep your plants thriving.

Overall, caring for agastache rupestris can be a rewarding experience if you follow proper plant care techniques. Remember to prune, propagate, and start from seed to ensure the health and longevity of your plants.

Understanding the blooming season and providing optimal growing conditions will enhance the beauty of your garden. Lastly, stay vigilant against pests and diseases to maintain the vibrancy of your agastache rupestris. Happy gardening!
