‘Tircolor’ is a bit smaller in growth but big in impact. Fan shaped leaves with gray/green, white and pink variegation. Excellent in mixed flower containers. This selection is more sun and heat tolerant than many of the sweet potatoes, and often will overwinter in our gardens with a little protection.
Ornamental sweet potatos are grown from tubers, and in Zones 10 and 11 would be considered perennial. In other zones they are annual, although the tubers can be dug up before the first frost and stored. Even as an annual, they are fun to grow because they are so fast and have such stunning color. In cooler climates sweet potatoes can be grown in full sun, but in hot dry locations they prefer some protection from afternoon sun.
