Most Dahlias Sold in India Are Built for a Climate India Doesn't Have
Showy garden dahlias grow from tuberous roots rather than from seed, and the hybrid varieties commonly sold in India were bred around a temperate growing cycle that includes a genuine cold dormancy period, lifting and storing the tubers over winter before replanting the following season. Most of India never gets cold enough for that natural dormancy to occur, and without deliberately lifting and storing the tubers during the hottest, driest part of the year, many dahlia varieties struggle to persist much past a single flowering season here, which is why they're often treated as one-season annuals in Indian gardens rather than the multi-year perennial they're marketed as elsewhere. Growers wanting dahlias to return reliably year after year generally need to actively manage this dormancy themselves, rather than leaving the tubers in the pot and expecting the plant to regenerate on its own the way most other flowering perennials on this site do.
