Annual. Blooms summer to fall frost. 2' - 3' tall. Full sun. These absolutely huge 5 - 6" cactus flowered Zinnias are a special collection by Botanical Interests and a dramatic color combination of the largest Zinnias available! The blend includes 'Cherry Time' (shades of red), 'Lilac Time' (shades of purple), and 'Snow Time' (very white).
The flowers' feathery, loosely arranged petals give them an airy appearance, and for long hot summers, nothing beats Zinnias for brilliant color and a long blooming period. They are drought tolerant and excellent massed in flowerbeds or in containers. Zinnias are very easy to grow, but may be susceptible to mildew in humid climates. Making sure that sprinklers do not hit them overnight or in the early morning will help prevent mildew. In all climates, it is preferable to water by soaking the ground (not from overhead) to keep leaves dry. Zinnias are a low-maintenance plant, but deadheading will extend the blooming period. Some gardeners recommend that tall flowering varieties be topped when young plants have produced 3 pairs of leaves. This will encourage basal branching and bushy plants. Zinnias are delightful as a fresh or dried cut flower and attract butterflies!
When to plant outside: RECOMMENDED. Sow in late spring 2 weeks after average last frost date. (Zinnias do not benefit from being planted early. Sow outside after weather is warm.)
When to start inside: Sow 6 weeks before average last spring frost. However, Zinnias do not transplant well. Best to start outside directly in the ground.
