The Corn Speedwell Flower is a delicate and charming bloom that's often overlooked, but it's definitely worth getting to know.
It's a low-growing, spreading plant that can form a dense mat, typically growing to be around 2-4 inches tall and 6-12 inches wide.
In ideal conditions, Corn Speedwell can produce an abundance of small, blue or pink flowers from late spring to early summer.
Flower
The corn speedwell flower is a beautiful sight to behold, with its elongating racemes of tiny stalked flowers at the ends of branching stems.
Each flower is tubular, measuring about 1/8 inch across, and has four round lobes, with the upper three slightly larger and the lower slightly smaller.
The flowers come in a range of colors, including deep blue, violet, and white, often streaked with a light greenish center.
Care and Maintenance
Watering Corn Speedwell requires a delicate balance. Overwatering can cause root rot, while under-watering can stress the plant, reducing bloom potential.
Water deeply, then allow the soil to dry slightly between waterings, adjusting your habits with the seasons. More water is needed during hot months, and less during cooler periods.
Consistency is key when it comes to watering, as erratic watering can dilute fertilizer and hinder flower production. Remember, too much water can be just as detrimental as not enough.
A balanced fertilizer with phosphorus is essential for maximizing flower production in Corn Speedwell. This type of fertilizer encourages more flowers instead of just foliage.
Best practices for fertilizing include timing applications to coincide with the plant's growth cycle, typically in the early spring.
Feeding the Flowers
To maximize flower production in Corn Speedwell, a balanced fertilizer blend with phosphorus is essential. This will encourage more flowers instead of just foliage.
A balanced fertilizer blend typically contains a mix of nitrogen, phosphorus, and potassium, along with trace elements. Organic options or water-soluble fertilizers are great alternatives.

Fertilize Corn Speedwell when it's preparing to bloom, usually in the early spring. This timing is crucial to ensure optimal flower production.
Over-fertilizing can lead to excessive leaf growth at the expense of flowers, so stick to the recommended ratios. Consistency is key to preventing dilution of fertilizer.
Water-soluble fertilizers are a great option, but be sure to follow the instructions for application and dilution. This will prevent burning the roots of the plant.
By following these simple guidelines, you'll be well on your way to growing a lush and vibrant Corn Speedwell with an abundance of beautiful blooms.
Deadheading: Keeping Blooms Coming
Deadheading is a simple yet effective way to keep your Corn Speedwell blooming all season long. By removing spent blooms, you're telling the plant to focus on producing more flowers instead of seeds.
This technique is especially helpful in the early spring when the plant is preparing to bloom, as fertilizing at this time can encourage more flowers. Fertilize with a balanced blend containing phosphorus to promote blooming.
Removing spent blooms also helps prevent the plant from wasting resources on seed production, which can lead to excessive leaf growth at the expense of flowers. Over-fertilizing can have the same effect, so stick to the recommended ratios.
By deadheading regularly, you'll be able to enjoy an abundance of vibrant blooms, which can turn a drab green space into a living Monet painting. These blooms are not just visually stunning, but they also attract pollinators like bees and butterflies, enhancing the ecological tapestry of your garden.
Optimizing Growth
Corn Speedwell prefers moist, well-drained soil. This delicate balance is crucial for optimal flowering.
Watering habits should adjust with the seasons – more during hot months, less when cooler. Consistency is key to avoid diluting fertilizer and hindering flower production.
Too much water can be just as detrimental as not enough. Overwatering can cause root rot, while under-watering can stress the plant, reducing bloom potential.
Deadheading, or removing spent blooms, is like hitting the refresh button on your Corn Speedwell. This continuous cleanup keeps your plant from wasting resources on seed production.
The ideal temperature range for Corn Speedwell is 60°F to 86°F. Stray outside this range, and the blooms might bail.
Water deeply, then allow the soil to dry slightly between waterings. This ensures the plant gets the water it needs without becoming waterlogged.
