Quantity per packet±500 seeds

New Mexico hummingbird mint here refers to Agastache neomexicana, an aromatic plant with small spikes of pink flowers. Its foliage releases a strong lavender and anise fragrance, while its 40 to 60 cm (15.7 to 23.6 in) stature suits a border or container. The seed supplier describes it as a biennial or short-lived perennial, generally living for two or three years. A modest bloom may already appear in the first year. This life cycle calls for planning replacement plants while enjoying their long flowering presence and visits from pollinating insects in the garden.

To begin growing it, sow indoors in early April or directly in the garden in June. The seeds need a very light covering, about 1 mm (0.039 in) deep. The seed supplier lists germination in under ten days at 18–20 °C; this refers to seedling emergence, not the appearance of flowers. Keep the surface moist without soaking it, and provide good light after germination. Then set the plants in full sun in well-drained soil, spacing them about 30 cm (11.8 in) apart. Gradually acclimatizing seedlings started indoors helps them adjust to the more variable conditions of the garden or balcony.

The leaves and flowers of this agastache can be used in herbal tea or as seasoning. Start with a small amount to appreciate their fragrance before adding more to a preparation. A location beside a path lets you follow the bloom and pick a few leaves without walking through the bed. Also leave some flower spikes for the insects that visit them. For winter, the seed supplier reports good survival in zone 4 under conditions suitable for the plant. Above all, maintain effective drainage and monitor clump renewal: its short lifespan is part of its normal cycle, even when it withstands cold.

Fertilization

New Mexico hummingbird mint. Adjust feeding to the actual fertility of the soil or the nutrients already in the growing mix. Soil that is already fertile does not automatically require another application. Follow the chosen fertilizer's instructions, and avoid feeding more when roots are struggling with poor drainage. Choose a position exposed to full sun with soil that allows excess water to drain away. Watering culinary herbs depends on the soil and the species. Check moisture below the surface and allow excess water to drain from containers.

Seasonal care

Growing in containers

Container growing

Container growing

New Mexico hummingbird mint. When growing in a container, consider the available root space, the drainage and the access to light as a whole.

Recipe and storage

Recipe idea

From garden to table

New Mexico hummingbird mint. Make an infusion with this plant's leaves after picking healthy parts and washing them thoroughly. Keep the cultivar identified and use only confirmed culinary parts. For an infusion, use the fresh or properly dried harvest and pour hot water over a small portion. Let the aroma develop, then strain before serving. Taste first without adding multiple ingredients to discover this plant's flavour. This preparation remains a culinary use and makes no claim of therapeutic effects. Harvest only the amount needed from young plants so they retain the ability to regrow. Use the freshly harvested portions without delay, and keep any dried portions in clean, dry conditions with labels that clearly identify them. Refrigerate prepared leftovers without delay. A seasoning plant should not be replaced by a similar-looking species or decorative flowers whose food use has not been established. A small first preparation will let you adjust the seasoning to your taste.
