Know before you buy
Since these arrive as dormant, bare-root tubers, you should start them indoors in pots about 6 to 8 weeks before your last frost date. Plant them 1 to 2 inches deep in well-drained soil with the concave side facing up, then move them outdoors once the danger of frost has passed.
Yes, because the 'Party Dress' variety produces exceptionally large flowers—up to 8 inches across—the stems can become top-heavy. Providing a small stake helps keep the plant upright and prevents the stems from snapping during wind or heavy rain.
No, this begonia is specifically bred for partial to full shade. Direct, intense sunlight will scorch the foliage and damage the delicate blooms, so it is best suited for shaded porches, patios, or under the canopy of trees.
In USDA zones 3 through 10, these are treated as annuals. If you live in a colder climate, you can dig up the tubers in the fall after the first frost, store them in a cool, dry place over the winter, and replant them the following spring.
You should space your tubers about 18 inches apart. This allows for adequate air circulation, which is essential for preventing fungal issues and ensuring the plant has enough room to reach its mature height of 24 to 36 inches.
