Ipomoea batatas 'Burgundy Cascade'
vineBurgundy Cascade is a ornamental sweet potato vine featuring striking deep burgundy to dark purple foliage that cascades elegantly from hanging baskets and containers.

Tuber/Transplant
1-2 weeks establishmentSmall rooted tuber or nursery transplant ready for planting into containers or garden beds
Plant after all frost danger has passed and soil is warm (60°F+). Keep soil warm and moist. Provide bright light immediately.
Early Growth
2-4 weeksVine begins emerging and producing first true leaves; foliage gradually develops deeper burgundy coloration
Maintain consistent moisture and warmth. Begin fertilizing with diluted liquid fertilizer every 2 weeks. Ensure full sun exposure for color development.
Vigorous Growth
6-10 weeksVines rapidly elongate, producing abundant deeply colored burgundy-purple heart-shaped leaves on trailing stems
Feed every 2 weeks with balanced or slightly higher nitrogen fertilizer to promote foliage. Water regularly. Prune or train as desired for shape. Support trellises if growing upright.
Peak Decoration
Throughout growing season (until frost)Plant reaches mature size with dense cascading foliage displaying rich burgundy coloration throughout; may produce small white or purple flowers (minor)
Maintain regular watering and feeding schedule. Continue pruning to maintain desired shape and prevent overcrowding. Watch for pests in warm climates.
Senescence/Dormancy
Fall through winterGrowth slows as temperatures cool; foliage may fade or die back with first frost in cold climates
Reduce watering and fertilizing. In zone 9b+, can overwinter outdoors; elsewhere, dig tubers before frost and store in cool, dry place, or treat as annual.

Uses
Container & Basket Décor
HouseholdBurgundy Cascade's dramatic deep purple foliage makes it ideal for hanging baskets, container gardens, and mixed plantings where its trailing growth habit creates visual impact and color contrast. The cascading vines can soften hardscapes and add vertical interest to patios and balconies. [source]
Trellis & Vertical Garden Training
HouseholdWhen provided with support structures, Burgundy Cascade can be trained vertically on trellises, arbors, or obelisks to create living walls or privacy screens with decorative foliage color. [source]
Edible Tubers (Minor Use)
CulinaryWhile ornamental varieties, the tubers are technically edible and can be roasted or baked, though ornamental cultivars may be less palatable and smaller than food varieties. Growing ornamental sweet potatoes offers dual functionality in edible gardens. [source]
Floral Arrangements & Foliage Displays
CraftThe distinctive burgundy foliage and trailing stems can be incorporated into fresh arrangements, wreaths, or mixed foliage displays for striking color and texture contrast with lighter-colored flowers. [source]
Pollinator Support
WildlifeThough flowers are minimal and inconspicuous, the small blooms attract bees and beneficial insects, adding minor pollinator value to container gardens and landscapes. [source]
Harvest Tips
Burgundy Cascade is grown for foliage, not harvest. Pinch or prune stems regularly throughout the growing season to encourage bushier, fuller growth and maintain desired shape. In zones 9b+, tubers can be dug in fall before hard frost (typically October-November) and stored in a cool (50-60°F), dry location for replanting next spring.
Fun Facts
- 🌱 Burgundy Cascade is derived from Ipomoea batatas, the same species as edible sweet potatoes, but has been selected for ornamental foliage color rather than tuber size or flavor.
- 🌱 The deep burgundy coloration intensifies with strong sunlight exposure and cooler temperatures, making it even more vibrant in fall.
- 🌱 Sweet potato vines can produce small flowers, but the ornamental varieties are grown primarily for foliage and can flourish without flowering.
