High Country Gardens Dahlia Collection

This collection features impressive dinner-plate sized blooms that measure between 6 and 10 inches across. The plants themselves reach a mature height of 36 to 48 inches, providing significant vertical interest in your garden beds.

Dahlias are tender perennials. In warmer climates (USDA zones 8-11), they can often be left in the ground year-round, while in cooler zones (3-7), you will need to dig up and store the tubers indoors over the winter to protect them from freezing temperatures.

The collection includes nine tubers in total, consisting of three tubers each of the 'Thomas Edison', 'Kelvin Floodlight', and 'Babylon Red' varieties.

For the best results and the most prolific flowering, these dahlias should be planted in a location that receives full sun. This ensures they have the energy required to produce their signature large blooms from mid-summer through the first frost.

Yes, these dahlias are excellent for cutting. Their long stems and large, vibrant blooms make them a popular choice for creating dramatic, high-impact floral arrangements for your home.

Plant the tubers at a depth of 1 to 2 inches. For optimal growth and airflow, space them at a density of one tuber per square foot.
