POQUITO® Dark Blue Agastache

POQUITO® ‘Dark Blue’ is a compact, low Agastache with upright spikes of violet-blue flowers above green foliage. This Terra Nova cultivar is suited to the front of a sunny border, a mixed perennial bed, or a container, where its freely produced flowers can be appreciated up close. ## Garden Use Use it as a small-scale color accent or plant several together for a repeating blue-violet display. ThinkPlants identifies it as POQUITO™ ‘Dark Blue’, cultivar code TNAGAPDB, with patent numbers PP28950 and EU51332. Its product information describes a compact mounding habit, flowers that continue through fall, summer heat and mildew tolerance, and drought tolerance once established. The [Terra Nova patent list](https://www.terranovanurseries.com/resources/patent-list/) confirms the cultivar and patent identifiers. ## Siting and Size Grow in full sun and provide well-drained soil. Exact size depends on source and growing conditions: ThinkPlants gives 13–15 inches tall by 14–15 inches wide, while another grower lists 10–15 inches in both directions. USDA zones 5–10 are reported by ThinkPlants; some retail listings use a narrower 5–9 range. Treat the wider breeder-supplier range as guidance and account for local winter conditions. ## Seasonal Interest Large spikes flower in summer and continue into fall. The low, bushy habit keeps the floral display close to the bed edge and makes it easy to combine with taller perennials. ## Maintenance Keep evenly watered while establishing, then reduce irrigation as roots develop; ThinkPlants describes drought tolerance after establishment. Use free-draining soil and remove faded stems if you want a tidier appearance.
