Know before you buy
The Nuit D'ete Dahlia is a perennial in warmer climates. If you live in a colder region, you will need to dig up and store the tubers indoors over the winter to ensure they return the following spring.
Since these dahlias reach a mature spread of about 18 inches, you should space them at least 18 to 24 inches apart to ensure proper airflow and room for the plants to thrive.
Yes, they are excellent for cut flower arrangements. Their unique, quill-shaped petals and deep, dramatic color add a striking focal point to any vase.
Because they grow to a height of 3 to 4 feet, it is often helpful to provide a stake or a small support cage. This prevents the heavy, 5-inch blooms from drooping or breaking during heavy rain or wind.
The tubers and leaves of the dahlia are toxic if ingested in large amounts. It is best to plant them in an area where your pets are not prone to digging or chewing on garden foliage.
These plants thrive in full sun, which means they need at least 6 to 8 hours of direct sunlight daily. Planting them in a spot with less light may result in fewer blooms and weaker stems.
