Giant Spreading Dayflower is a vigorous, moisture-loving perennial found in humid, subtropical Florida environments, producing small but vivid blue flowers over a long season. It thrives in moist, rich soil with partial shade and regular watering, making it suitable for rain gardens or pond margins. This variety is primarily of botanical interest and requires ample space as it spreads readily in warm, wet conditions.
