A native of Mexico, Torch Tithonia grows at a slow burn until midsummer heat triggers an explosion of red-orange blooms that blaze into fall. Reaching up to 6 feet tall, the flowers glow like torches held aloft, as though, like the trickster Prometheus, they too have stolen a lick of fire from Zeus’s hearth. And like generous Prometheus, Torch Tithonia allows us to keep the flame of this flower alive, as we save its abundant seed from season to season.
