Know before you buy
The Cora Red F1 is a hybrid variety specifically bred for high tolerance to aerial Phytophthora, a common disease that often affects vinca. It also offers more uniform growth and a consistent bloom time compared to open-pollinated varieties.
Yes, these seeds should be covered with soil during the germination process. They do not require light to sprout, so ensure they are tucked into the growing medium at the recommended depth.
Since these plants reach a spread of 22 to 25 inches, you should space them at least 2 feet apart to allow for proper airflow and healthy development.
For best results, maintain a daytime temperature between 75-80°F and a nighttime temperature between 65-70°F. During the germination phase, keep the soil consistently warm at 70-75°F.
With a height of 14-16 inches and a wide, uniform habit, they work well in large containers or garden beds. Ensure the container has adequate drainage, as these plants prefer moderate watering.
Under optimal soil temperatures of 70-75°F, you can expect to see germination within 4 to 6 days.
