Uses Notes: 

Works great in landscapes as an annual ground cover, as well as in combinations and containers by themselves.  The plant is very adaptable, working in both sun and shade conditions, atlhough the colors are deeper and brighter in full sun than they are in shadier environments where colors are tinged with more green.

Maintenance Notes: 

Ipomoeas are great additions to combination planters, but they can sometimes overwhelm less vigorous plants. If you are like me you can let your combination plants duke it out Darwinian style, however, if you prefer to keep a more balanced look to your combination planters, you can cut back or remove stems at any time.

Ipomoeas also make great annual groundcovers in the landscape. They love the heat and humidity (growing up to 36" a week in the Deep South), cooler temperatures and low humidity cause them to stay more compact.

While Sweet Potatoes all come from the same parent material out of Southeast Asia, there is a big difference between the Sweet Potato you buy in the store and the tubers produced by the Sweet Caroline and the Illusion plants. Commercial sweet potatoes have been bred for over 100 years selecting for those with the best sugar to starch content (hence the name SWEET Potato), the ornamental have been bred to produce good leaves and no tubers, though they do form, they are composed of almost pure starch and no sugar; making them a poor choice for eating. So yes you can eat the tubers, but don't expect anyone to come back for seconds! Also always be careful when eating any ornamental plant unless you know how it was grown, and if pesticides or fungicides were used on it before you got it; a tuber is a storage root, and yes they store chemical as well as starch.

An application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.

With more sunfast coloring than some older sweet potato vines, this selection keeps its lime green color all season. It is also a bit less rambunctious than some, making it easier to work with as a trailing plant for your combination containers and hanging baskets. This plant also makes an excellent annual groundcover in landscapes where it has proven to be extremely heat and humidity tolerant.

  • Wow! I will put these in every year! They add such vibrant color to my borders. I also used them in a pot with Bordeaux petunias, and they look amazing. They require very little care. An insect has made tiny holes in the leaves, but once I sprayed, they looked great again! (No fault of the plant or Proven Winners.) I really love this plant!

    Outstanding My favorite plant, I recommend to others all the time and explain the reasons why I like it so much.

  • Bought one in May, when it was about 5 inches in length. Placed in large barrel pot at front of house, where it gets 3 hours direct sun, late morning to early afternoon.
    Today it is about 5 feet in length and has taken on a mounded appearance as well. The color is intense, the growth vigorous and care is easy.
    Must water regularly and often 2x daily on hottest days. Not sure if it even need fertilizer/feeding but it has not hurt.

    One item of note: Slugs LOVE to munch on this plant, so take great care to check regularly for damage and even better plant far from where slugs like to live.

    Overall one of my 4 or 5 most favorite PW plants.

    Above Average Superior performance, among my favorites, would recommend to others.

  • Beautiful color, grows great in my containers I have on pedestals. I let them grow long. I grow them in full sun and they do terrific. Enjoy!
