Container gardening has become a popular trend in recent years, offering a convenient and versatile way to grow plants, especially for those with limited space. Among the many plants suitable for container gardens, the ornamental sweet potato vine stands out for its lush foliage and vibrant colors. However, what many gardeners may not know is that the tubers of the ornamental sweet potato vine, although they look similar to the ones you buy at the store, aren't very tasty. So, what should you do with them instead?
First, let's understand a bit more about these tubers. Ornamental sweet potato vines (Ipomoea batatas) are grown primarily for their attractive leaves, which come in a variety of colors such as purple, chartreuse, and variegated. The tubers are a by - product of the plant's growth. Unlike the edible sweet potato varieties, the ornamental ones are bred for their aesthetic appeal rather than their flavor.
One of the best things you can do with these tubers is to use them for propagation. Propagating from tubers is a relatively simple process. Start by selecting healthy tubers. Look for ones that are firm and free from any signs of rot or damage. You can then cut the tubers into sections, making sure that each section has at least one or two 'eyes' (similar to potato eyes). These eyes are the growth points from which new shoots will emerge.
After cutting the tubers, let the cut surfaces dry for a day or two. This helps to prevent rot when you plant them. Fill a container with a well - draining potting mix. You can use a commercial potting soil or make your own by combining equal parts of peat moss, perlite, and vermiculite. Plant the tuber sections about 2 - 3 inches deep in the soil, with the eyes facing upwards. Water the soil thoroughly but be careful not to over - water, as excessive moisture can cause the tubers to rot.
Place the container in a warm, sunny location. Ornamental sweet potato vines thrive in full sun to partial shade. In a few weeks, you should start to see new shoots emerging from the tubers. Once the plants have grown a bit, you can transplant them into larger containers or use them to fill in gaps in your existing container garden.
Another creative way to use these tubers is in decorative arrangements. You can clean the tubers and use them as part of a fall or winter centerpiece. Combine them with dried flowers, pinecones, and other natural elements to create a rustic and charming display. You can also paint the tubers in different colors to add a more festive touch, especially during the holiday season.
If you're feeling adventurous, you can try using the tubers to create a living sculpture. Plant the tubers in a large container in a specific pattern or shape. As the vines grow, you can train them to follow the desired form. This can be a fun and unique addition to your container garden, adding an element of artistry and creativity.
It's important to note that while the tubers of ornamental sweet potato vines aren't suitable for eating, they are non - toxic to humans and pets. However, it's still best to keep them out of reach of children and animals, as they may not be accustomed to these types of plants.
In conclusion, the tubers of ornamental sweet potato vines offer more than meets the eye. Instead of discarding them, you can use them for propagation, decorative purposes, or even to create living art in your container garden. So, the next time you find these tubers in your container garden, don't hesitate to get creative and make the most of them.
