About Dahlia
Dahlia brevis, known as Atlacomulco Dahlia, is a wild dahlia species native to Mexico, distinguished by its simple and elegant flowers. Its petals are typically pink to purple hues with a vibrant yellow center, ideal for pollinator gardens or as part of a flowering hedge. Its compact habit and abundant blooms make it perfect for borders or pots in sunny patios.

Care tips
It requires full sun for optimal flowering, at least 6 hours daily. Watering should be regular, keeping the substrate moist but not waterlogged, especially during flowering; reduce watering in winter. It prefers well-drained soil, rich in organic matter, and with a slightly acidic to neutral pH. A common mistake is not providing enough light, which results in sparse flowering and leggy stems.
