Summary
Agastache has always been a back-of-the-border plant. The Poquito series is the argument that it does not have to be.
'Butter Yellow' forms a low, tight dome around 10 to 13 inches tall and 15 across — small enough to edge a walkway or fill a modest container — and then produces flower spikes at nearly full scale for the genus. The florets are a soft butter yellow tipped with peach, dense along the spike rather than scattered, and they run from June through September.
Its performance record is unusual for a dwarf. At the University of Georgia trial gardens it took a Classic City Award against six other agastache cultivars, and the judges specifically noted that where most hyssops disappear into their surroundings on wispy stems, this one held its own visually despite being the shortest plant in the trial.
Foliage is fine-textured, aromatic, and stays green through the season. Hummingbirds and bees find it quickly; deer and rabbits do not.
Care
Poquito Butter Yellow Agastache Care
Full sun. The compact habit depends on it — in shade the plant stretches and loses the density that makes it worth growing.
Average to dry, well-drained soil. Lean ground is genuinely better here; fertile soil produces floppy growth on a plant whose whole appeal is being tidy. Sharp drainage through winter is the single most important condition.
Water regularly the first season, then only in real drought. It tolerates dry sites and extreme heat once rooted in.
Fertilizer is not recommended and is counterproductive in most soils. If the site is genuinely poor, a light spring application of slow release fertilizer is enough for the year.
Deadhead spent spikes through summer to keep the flush going, then leave some standing into winter — the seed heads feed songbirds and the stems shelter the crown. Cut back to the base in early spring.
Container growing: it is well suited to pots, which is much of the point of the series. Use a gritty free-draining mix, water when the top inch is dry, and avoid saucers that hold standing water. Plants hardy in the ground may require winter protection when grown in containers in colder zones.

Additional Information
What are some common names for this plant?
Several are in regular use, listed from most to least common:
- Dwarf hummingbird mint
- Hyssop
- Anise hyssop
- Licorice mint
What is the difference between the Poquito and Kudos series?
Both are compact, but Poquito is the smaller of the two. Kudos varieties hold around 17 to 20 inches; Poquito runs closer to 10 to 13. If you want a hummingbird mint for a container, an edge, or a narrow bed, Poquito is the one built for it.
Does a dwarf agastache get smaller flowers too?
No, and that is the notable part. The inflorescences are large relative to the plant, which is why it stayed visible in trials against much taller cultivars. The dwarfing is in the habit, not the flower.
Is the foliage really edible?
Agastache leaves are aromatic and have a long history of use in teas. That said, we grow and sell this as an ornamental, not as a culinary crop, so it should not be treated as a food plant.
Will it come back reliably in Zone 5?
It is rated hardy to Zone 5, and cold itself is rarely the problem — winter wet is. In Zone 5 and 6, plant it somewhere with genuinely sharp drainage, ideally with a southern exposure, and leave the stems standing over winter. Under those conditions it returns dependably. It sits comfortably among our other Drought-Tolerant Plants.
