About Asiatic dayflower
Commelina communis, also known as Asiatic dayflower or liten himmelsblomma in Swedish, is an annual herbaceous plant belonging to the Commelinaceae family. It is characterized by its vibrant blue, three-petaled flowers, though one petal is often smaller and less conspicuous, which bloom in the morning and wilt by midday. It is ideal for ground cover in naturalistic gardens, borders, or in hanging baskets, providing an ephemeral yet charming splash of color.

Care tips
This plant prefers full to partial sunlight and moist, well-drained soil; it tolerates a wide range of soil types. Watering should be regular to maintain moisture, especially in hot and dry climates. It's important to avoid waterlogging, as this can lead to root rot. A common mistake is underestimating its spreading capability, as it can become invasive under favorable conditions, so controlling its growth is recommended.
