**Evolvulus nuttallianus – Starflower**
**Botanical Name:** *Evolvulus nuttallianus*
**Family:** Convolvulaceae (Morning Glory Family)
**Common Names:** Starflower, Blue Star Flower, Rainflower
**Origin:** Native to North America.
**Growth Habit:** A low-growing, spreading perennial shrub that typically reaches 30–60 cm in height. The stems are semi-woody and densely covered with white hairs. Leaves are alternate, small, and lance-shaped.
**Flowers:**
The most striking feature of this plant is its small, star-shaped blue or purple flowers that bloom throughout the year, especially during warm seasons. Each flower has a central white star-like pattern, giving it a unique and eye-catching appearance. Interestingly, the flowers of the Blue Star Flower open in the morning and close by the afternoon.
**Light Requirements:** Full sun to partial shade. Insufficient light may result in leggy growth and reduced flowering.
**Watering:** Requires consistent moisture, especially during summer. Water daily if needed, but avoid overwatering. In winter, reduce watering frequency.
**Soil:** Well-drained soil is ideal. It can tolerate a range of soil types but thrives in sandy or loamy conditions.
**Fertilization:** Apply a balanced, fast-acting fertilizer once a month during the growing season to promote healthy growth and abundant flowering.
**Pruning:** Trim back overgrown or tired plants to encourage bushier growth and maintain a compact shape. Pruning also helps improve air circulation and prevent disease.
**Propagation:** Easily propagated through stem cuttings. Take 3–4 inch cuttings from healthy branches, remove the lower leaves, and insert them into a well-drained medium at an angle. Roots usually develop within a week. Spring and autumn are the best times for propagation.
**Landscape Use:**
Starflower is widely used in landscaping for its ornamental value. It’s perfect for garden beds, rock gardens, borders, and even as a ground cover. Its continuous blooming makes it a great choice for adding color to your outdoor space all year round.
**Additional Notes:**
This hardy plant is easy to grow and requires minimal care once established. It's drought-tolerant once matured and attracts pollinators like bees and butterflies. The soft, silvery foliage adds a nice contrast to the vibrant flowers.
Whether you're looking to enhance your garden with a reliable bloomer or create a low-maintenance landscape, *Evolvulus nuttallianus* is an excellent choice. Its beauty and resilience make it a favorite among gardeners and landscapers alike.
