2.1 Cultivars and Characteristics

Sunflowers belong to the genus Helianthus and are native to North America. They exhibit a wide range of sizes, from petite varieties standing a few inches tall to towering giants reaching over 12 feet. Their iconic blooms consist of a central disc surrounded by a halo of colorful ray florets. Sunflowers come in an array of hues, including yellow, orange, red, and purple.

2.2 Growing Conditions

Sunflowers thrive in full sun and well-drained soil. They require ample moisture, especially during the initial growth stages. Avoid overwatering, as this can lead to root rot. Fertilize regularly to promote healthy growth and abundant blooms.

2.3 Uses

Sunflowers serve multiple purposes beyond their aesthetic value. Their seeds are a nutritious source of vitamins, minerals, and antioxidants. The oil extracted from these seeds is used in cooking, cosmetics, and biofuels. Sunflowers also attract pollinators, making them beneficial for gardens and the environment.

3. Calla Lilies: Elegance and Symbolism

Calla lilies belong to the genus Zantedeschia and are native to southern Africa. Known for their trumpet-shaped flowers, calla lilies come in various colors, including white, yellow, pink, and purple. Their elegant blooms are often solitary, rising from long stems. Calla lilies symbolize purity, innocence, and beauty.

3.2 Growing Conditions

Calla lilies thrive in boggy areas or consistently moist soil. They prefer bright indirect light or partial shade. Mulch around the plants to retain moisture and suppress weeds. Avoid overwatering during the summer months to prevent root rot.

Deadhead spent blooms by removing them from the stem. This encourages new flower production and prevents the plant from putting energy into seed production.
