Vegetative Growth
4-8 weeksVigorous vining growth with numerous heart-shaped leaves in bright lime-green color; stems rapidly elongate
Provide support structure if desired, or let trail. Fertilize every 2 weeks with balanced or nitrogen-rich fertilizer for foliage. Pinch tips occasionally for bushier form.
Mature Foliage
6-10 weeks, continuing through seasonDense canopy of lime-colored leaves covering vines; plant reaches full size and spreads widely
Maintain consistent watering and feeding schedule. Monitor for pests and diseases. Prune to control size or shape as needed.
Peak Display
Through summer and early fall until frostLush, vibrant chartreuse foliage at maximum color intensity; plant fully established and sprawling
Deadhead any small morning glory-like flowers if you want energy focused on foliage. Continue regular watering and fertilizing. Perfect for photographs and garden showcasing.
End of Season/Dormancy
4-8 weeks or until frostGrowth slows as temperatures cool; foliage may fade slightly or show stress if exposed to frost

Sweet potato leaves (edible in many cultivars)
CulinaryWhile 'Margarita' is bred primarily for ornamental foliage, sweet potato vine leaves are edible in general and nutrient-rich, though this variety is typically grown for decoration rather than harvest. [source]
Harvest Tips

Pinch or prune vines anytime to maintain desired shape and encourage bushier growth. Cuttings can be taken and rooted in water or moist soil for propagation before frost.
Fun Facts
- 🌱 The 'Margarita' cultivar was specifically bred to produce that eye-catching lime-green color, making it a relatively modern addition to ornamental gardening compared to traditional sweet potato varieties.
- 🌱 Sweet potato vine plants are actually perennial in their native tropical regions and can live for many years, but are typically grown as annuals in temperate climates or overwintered indoors.
- 🌱 The small flowers that occasionally appear are typical morning glory blooms (sweet potato vine is in the Convolvulaceae family), usually in shades of pink, purple, or white, though gardeners often pinch them off to direct energy to foliage.
