Plant Profile: Zinnia

Zinnias are easy to care for, resilient to heat and drought, and come in a variety of colors. These beloved warm-season annuals, part of the daisy family, are simple to cultivate. They are available in an array of sizes, ranging from 6 inches to 4 feet tall, and feature different bloom types: single blooms (with a single row of petals and a visible center), double blooms (with multiple rows of petals and hidden centers), and semi-double blooms (which have several rows of petals but still show their centers). Additionally, zinnias exhibit various shapes, such as beehive, button, and cactus forms.

Depending on their height, zinnias can be positioned in the front or back of borders, planted in containers, or grouped together for vibrant seasonal displays. They thrive in average, well-drained garden soil and require full sunlight. It's important to keep them adequately watered while they establish themselves. Zinnias provide continuous color throughout the growing season. To promote further blooming, deadhead the flowers, but remember to leave some seed heads for the birds.

The Zinnia family includes numerous varieties and cultivars, such as the hybrid 'Profusion' Series. This hybrid is a cross between Zinnia angustifolia, known for its disease resistance, and Zinnia elegans, which boasts larger flowers. This combination results in plants that are drought-tolerant, heat-resistant, and low-maintenance, with robust foliage that deters insects and keeps deer and rabbits at bay.

However, zinnias can be prone to powdery mildew, so it's essential to avoid overcrowding them to ensure proper air circulation.
