Creeping zinnias, scientifically known as Sanvitalia procumbens, are indeed annual plants. This means that they complete their entire life cycle, from germination to seed production, within a single growing season. As a result, they will not come back on their own the following year. However, their beautiful blooms and easy care make them worth replanting year after year.
To establish creeping zinnias in your garden, you have a couple of options. The most common method is to purchase potted nursery starts in the spring, once the threat of frost has passed. These young plants are already established, allowing you to enjoy their colorful flowers sooner. Look for healthy starts with green, well-branched foliage and no signs of pests or diseases.
If you prefer a more hands-on approach or want to save money, you can also grow creeping zinnias from seed. This can be a rewarding experience as you witness the entire growth process from seed to flowering plant. Sow the seeds indoors about 4 to 6 weeks before the last frost date or directly in the garden after the danger of frost has passed. Keep the soil moist and provide sufficient light for the seedlings to thrive.
When it comes to caring for creeping zinnias, they are relatively low-maintenance plants. They prefer full sun but can tolerate some light shade. Ensure that they receive at least 6 to 8 hours of direct sunlight daily for optimal growth and abundant blooms. Well-draining soil is essential to prevent root rot, so amend heavy or clay soils with organic matter.
Water your creeping zinnias regularly, keeping the soil consistently moist but not waterlogged. Avoid overhead watering, as wet foliage can lead to fungal diseases. Instead, utilize methods like drip irrigation or soaker hoses to water the plants at their base.
To encourage continuous blooming, deadhead spent flowers regularly. This practice removes the spent blooms, preventing the plant from putting energy into seed production and redirecting it towards new flower production. Additionally, fertilize your creeping zinnias every 4 to 6 weeks with a balanced, water-soluble fertilizer to promote healthy growth and vibrant blooms.
As the growing season comes to an end, you can collect the seeds from your creeping zinnias for future planting. Simply allow the flowers to dry on the plant, and the seeds will develop inside the dried flower heads. Once the flower heads have turned brown and crispy, gently shake or rub them to release the small, dark seeds. Store the seeds in a cool, dry place until you are ready to plant them the following spring.
While creeping zinnias do not come back on their own each year, their abundant blooms and carefree nature make them a worthwhile addition to any garden. Whether you choose to purchase nursery starts or grow them from seed, these charming annuals will provide continuous color and beauty throughout the growing season.
