Scientific Name: Zinnia elegans
Height: Zinnias typically grow to a height of 76-102cm (30-40 inches). This information is crucial in determining where to plant them in your garden to ensure they have enough space to grow without overcrowding.
Days to Maturity: Zinnias have a maturity period of 75-95 days. This means that from the time you plant the seeds, it will take approximately 2.5 to 3 months for the zinnias to reach full maturity and start blooming.
Sun Preference: Zinnias thrive in full sun, which means they require at least 6-8 hours of direct sunlight per day. Planting them in a location with ample sunlight is essential for their growth and blooming.
Plant Type: Zinnias are classified as hardy plants, indicating that they are robust and can withstand various growing conditions. Their hardiness makes them suitable for beginner gardeners or those looking for low-maintenance plants.
Spacing: When planting zinnias, ensure to space them adequately, with a recommended spacing of 23cm (9 inches) between each plant. Proper spacing allows the plants to receive sufficient airflow and sunlight, promoting healthy growth.
Pinching: It is advisable to pinch back zinnias when they reach a height of 20-30cm (8-12 inches). Pinching helps promote bushier growth and more abundant flowering by encouraging lateral branching.
Appearance : Zinnias are available in a wide array of colors, shapes, and sizes. They come in single or double petaled flowers in almost all colors of the rainbow
Harvesting : use the wiggle test, grab the stem approximately 20cm from the flower and gently shake, if the stem is droopy or bends it isn’t ready. If it is stiff it is ready to harvest. Do not put these flower in a cooler!
Vase life : Vase life can be expected up to 7 days
Special Features: Zinnias are often associated with thoughts of friendship, loyalty, and endurance. They can be given as gifts to convey feelings of affection and well wishes. Zinnia flowers have a long blooming period, lasting from early summer to fall, especially in areas with mild climates. Deadheading spent blooms can encourage continuous flowering. Breeders have developed numerous hybrid zinnia cultivars with improved traits such as disease resistance, longer stems for cutting, and unique flower shapes like double or pom-pom blooms. They are open pollinated blooms so are easy to breed with.
