White mouth dayflower (Commelina erecta)
Also known as: Dayflower, Slender Dayflower
The White mouth dayflower (Commelina erecta) is a perennial wildflower commonly found in coastal uplands, scrub habitats, and pinelands. It features two prominent purplish-blue petals at the top of the stem, with a smaller white petal positioned below them. The presence of this small white petal resembling an open mouth is the reason for the "white mouth" descriptor in its name.

What Is the Ideal Temperature Range for White mouth dayflower?
The ideal temperature range for Commelina erecta is between 75°F and 85°F. This range provides the optimal conditions for photosynthesis and other metabolic processes, ensuring healthy growth and vibrant foliage. Maintaining these temperatures helps the plant thrive by supporting efficient water uptake and nutrient absorption.
What Soil is Best for White mouth dayflower?
Commelina erecta thrives in soil that offers excellent drainage. Well-drained soil prevents waterlogging, which can lead to root rot. This plant benefits from the prevention of excess water accumulation around its roots, keeping them healthy and robust. This plant prefers moderately fertile soil. A nutrient-rich substrate provides essential elements that promote healthy growth and vibrant foliage, contributing to the plant's resilience in varying conditions. While it tolerates dryness, Commelina erecta performs best in consistently moist soil. This supports sustained hydration of the plant tissues, encouraging lush growth and vibrant flowering.
How to Fertilize White mouth dayflower?
When fertilizing Commelina erecta, apply a balanced, water-soluble fertilizer at half the recommended strength. For example, if the label suggests 20 ml per gallon, use 10 ml. This plant doesn't require excessive nutrients, so err on the side of caution to avoid over-fertilization.
How to Prune White mouth dayflower?
Begin by sterilizing your pruning shears to prevent infection. Identify any dead or diseased stems, and remove them first by cutting them back to the nearest healthy node. Next, target stems that are overly long to maintain the plant's shape, making cuts above a node at a slight angle to encourage new growth.
How to Propagate White mouth dayflower plant?
1
Gather seeds from mature Commelina erecta plants after flowering in late summer. Ensure seeds are dried and stored in a cool, dry place until sowing in early spring.
2
Select healthy stems and cut them into sections about 4-6 inches long in spring. Remove lower leaves and immerse the cut end in rooting hormone before planting in soil.
3
Divide mature plants in early spring by gently separating clumps using a spade. Each division should have adequate roots, and then they should be replanted in prepared soil.
How to Repot White mouth dayflower plant?
1
Repotting time for Commelina erecta is signaled by roots emerging from the drainage holes or slowed growth. In early spring, new growth begins, making it an ideal time to provide fresh nutrients with new soil.
2
Select a pot that is one size larger than the current one, with adequate drainage holes. This will allow for ample root space, preventing over-crowding and ensuring the roots have oxygen, which is crucial for healthy growth.
3
Use a well-draining soil mix composed of loam, sand, and organic matter. This combination ensures proper drainage while retaining enough moisture for nutrient uptake, contributing to a robust and thriving plant.
