Isotoma axillaris, commonly known as Laurentia, is part of the Bellflower family, Campanulaceae. Isotoma fluviatilis is Blue Star Creeper and White Star Creeper and are discussed on different pages. Laurentia is popular among gardeners for its delicate beauty and low-maintenance nature. With its dainty flowers, lush foliage, and adaptability to various garden settings, Laurentia has become a sought-after addition to landscapes, borders, and containers.
How to Grow Laurentia
One of the standout features of Laurentia is its ability to thrive in various climates, from temperate regions to warm and tropical areas.
- These plants prefer well-draining soil with good fertility and a neutral to slightly acidic pH. Amending the soil with compost or organic matter before planting can provide the nutrients for healthy growth.
- Laurentia is known for its resilience in partially shaded locations. While it can tolerate full sun, it appreciates some protection from intense afternoon sunlight, especially in hot climates such as the Upstate. In regions with scorching summers, providing partial shade during the hottest part of the day can help maintain vibrant foliage and prevent stress.
- Regular watering is essential during the plant’s establishment period, helping it develop a strong root system. Once established, Laurentia displays moderate drought tolerance, but monitoring soil moisture and providing supplementary water during extended dry spells is important. Watering at the base of the plant reduces the risk of fungal diseases and promotes healthy growth.
- Laurentia are relatively disease and pest-resistant, but it’s still a good practice to monitor for any signs of pests and address them if necessary.
Leaves and Flowers
Laurentia’s leaves contribute to its overall attractiveness with its lush and slightly succulent appearance. They are typically small, ovate, and glossy, creating an appealing backdrop to the delicate flowers. Laurentia flowers are the focal point of the plant, featuring a profusion of star-shaped blooms. The flowers come in many captivating colors, including shades of blue and lavender. Laurentia blooms throughout the growing season, attracting pollinators like bees and butterflies to the shade garden.
Uses in the Garden
Laurentia’s long blooming habit makes it a valuable asset in shade garden design. When planted en masse, Laurentia can create a captivating sea of color, forming a serene and enchanting atmosphere in garden landscapes. Laurentia acts as filler in the landscaper or in containers, providing all season long blooms.
