Ipomoea is a genus of plants that belong to the family Convolvulaceae. It consists of both the sweet potato vine family and the morning glory vine family. Ipomoea plants are native to the tropical and subtropical areas of North and South America, Africa, and Asia. With over 500 species, Ipomoea is a diverse and fascinating group of plants known for their beautiful flowers and unique growth patterns.
Our Selection of Sweet Potato Vine
At Martin Garden Center, we have a double decker table devoted solely to sweet potato vines. Generally, this carries 200+ containers and it is covered in 6-8 varieties at any given time. We do not grow this plant at Martin Garden Center because our local vendors carry a plethora of varieties. Some of the varieties include the Sweet Georgia series, Marguerite, Dwarf Marguerite, Blackie, Ace of Spades, Black Heart, Solar Power, Tricolor, Rusty Red and more. Always more.
Growing and Caring For Sweet Potato Vine
Ipomoea is well-adapted to different soil types, ranging from sandy to loamy, as long as it is well-drained. These plants prefer full sun, although some species can tolerate partial shade. It is worth noting that some Ipomoea species can be invasive in certain regions, particularly in tropical and subtropical areas where they can outcompete native vegetation. As with any plant, it’s essential to be mindful of the potentially invasive nature of certain Ipomoea species and to plant them responsibly, following local regulations and guidelines.
Sweet Potato Vine is susceptible to several pests including deer and other leaf munching pests such as caterpillars later in the season (late May to June). Because of the excessive growth of the vine, we normally don’t recommend any treatment because the vine will regrow so quickly that you generally won’t notice any effects of munching on your vine.
One unique aspect of Sweet Potato Vine is its vigorous growth habit. Its creeping/trailing growth habit making it ideal for use as ground covers or in hanging baskets. One small 4″ vine can become 8-10 limbs each spreading 8-10 feet by mid-summer.
Uses in the Garden
The Ipomoea (Sweet Potato Vine) is a versatile plant that serves multiple uses in the garden, offering both aesthetic appeal and functional benefits. Here are some of its primary applications:
1. Ground Cover
- Ipomoea’s vigorous spreading habit makes it an excellent ground cover, quickly filling in bare spots and suppressing weeds.
- Ideal for slopes and erosion control, as its dense foliage helps stabilize soil.
2. Hanging Baskets & Containers
- Its trailing vines spill beautifully over the edges of hanging baskets, window boxes, and containers, adding a cascading effect.
- Pairs well with upright flowers like Petunias, Calibrachoa, and Geraniums for dynamic contrast.
3. Companion Planting
- Works well with bright annuals and perennials, enhancing color contrast with its vibrant foliage (chartreuse, purple, or bronze tones).
- Often used in mixed container plantings to add texture and depth.
4. Edging & Borders
- Planted along pathways, garden borders, or raised beds, it creates a soft, flowing edge.
- Provides a lush, tropical feel when paired with bold foliage plants like Cannas or Elephant Ears.
5. Pollinator Gardens
- Though mostly grown for its foliage, some varieties may produce small trumpet-shaped flowers that attract bees and butterflies.
6. Seasonal Interest
- Offers three-season color in warm climates (spring through fall).
- In colder climates, it is commonly grown as an annual, thriving in summer and early fall.
7. Urban & Small Space Gardening
- Excellent for balconies, patios, and rooftop gardens where space is limited.
- Can be trained up a small trellis or allowed to spill down from vertical planters.
