The ‘Blue Bayou‘ Dahlia is a stunning anemone-flowered (or powder-puff) cultivar featuring a distinct cushion of dark, quill-like purple-magenta florets surrounded by a frilly “skirt” of pale lavender petals with striking blue undertones. Reaching 36 to 40 inches in height, they bloom continuously from mid-summer until the first frosts and make excellent cut flowers. [1, 2]
Growing & Care Details
- Bulb Planting: Plant after the danger of the last spring frost in a sunny, well-drained location. The tubers (often loosely referred to as bulbs) should be buried about 4 to 6 inches deep with the growing eye facing up. [1, 2, 3]
- Light & Soil: Requires full sun (6 to 8 hours daily) and moderately acidic, well-drained garden soil. [1, 2]
- Watering & Feeding: Water deeply about once a week; the soil should be kept moist but not waterlogged to prevent the tubers from rotting. Fertilize every few weeks with a low-nitrogen fertilizer to encourage blooms. [1, 2]
- Winter Hardiness: Dahlias are winter hardy only in USDA zones 8–10. In colder climates, the tubers must be dug up in the fall and stored indoors in a cool, dry, frost-free location. [1, 2]
