Know before you buy
Yes, the foliage is edible and offers a unique culinary addition to your garden. You can harvest the leaves throughout the growing season to use in stir-fries or salads, similar to spinach.
Because these plants have a trailing habit, a container with at least a 5-gallon capacity is recommended to allow the tubers enough room to develop. Ensure your pot has adequate drainage holes to prevent waterlogging.
While the plant is adaptable to partial shade, it performs best and produces the highest yield of tubers in full sun. Aim for at least 6 to 8 hours of direct sunlight daily for optimal growth.
These plants thrive in loose, sandy-loam soil with a slightly acidic pH between 5.8 and 6.2. If your garden soil is heavy clay, consider amending it with compost or sand to improve drainage and tuber development.
The Makatea Treasure Island sweet potato is a perennial, but it is only winter-hardy in frost-free climates. In colder regions, you will need to treat it as an annual or bring your containers indoors before the first frost.
