Know before you buy
These are classified as dinnerplate dahlias, meaning you can expect the blooms to reach 10 inches or more in diameter when the plant is well-maintained.
Yes, because these dahlias grow up to 5 feet tall and produce heavy, large blooms, it is essential to stake them early in the season to prevent the stems from snapping in the wind or under the weight of the flowers.
For optimal airflow and growth, space your tubers 18 to 24 inches apart. This spacing helps prevent fungal issues and ensures each plant has enough room to reach its full height.
Absolutely. Their large, fluffy structure and unique color blend of peach, lavender, and yellow make them an excellent choice for a centerpiece or as a focal point in a bouquet.
These dahlias require full sun, which means at least 6 to 8 hours of direct sunlight per day. Without sufficient light, the plants may become leggy and produce fewer, smaller blooms.
You can expect the first blooms to appear between 80 and 100 days after planting. This timeline can vary slightly depending on your local climate and soil temperature.
