Know before you buy
If you live in USDA hardiness zones 8-10, these dahlias can remain in the ground as perennials. In zones 3-7, they are treated as annuals, meaning you should dig up and store the tubers in a cool, dry place once the first frost kills the foliage.
Yes, this variety is well-suited for containers. Ensure your pot has adequate drainage holes and is large enough to support the 30-inch height of the plant.
The Tahiti Sunrise produces large, heavy blooms that can reach up to 6 inches across. Staking provides the necessary structural support to keep the stems upright and prevent them from bending or breaking during heavy winds or rain.
This dahlia requires full sun, which means at least 6 to 8 hours of direct sunlight per day. Adequate light is essential for the plant to produce its signature vibrant, tri-color blooms throughout the season.
Each order contains 3 tubers, which are ready to be planted in the spring once the danger of frost has passed.
Absolutely. The Tahiti Sunrise is specifically noted for being an excellent cut flower, producing an abundance of blooms from mid-summer until the first frost.
