Commelina dianthifolia
Bird-bill Dayflower
Considered a weed in many parts of the world, this plant is a native of East Asia. It is almost succulent in appearance as it has thick watery stems with nodes from which new branches and leaves grow, and small flowers consisting of two mouse-ear-shaped upright sky-blue petals and one bear-like lower petal. The flowers, as its common name suggests, last only a day - by mid-day of the day a flower blooms it turns to a jelly-like substance. Spreads along the ground as stems root as they grow horizontally.The flowers appear from mid Summer to early Autumn. The 'Bird-bill Dayflower' - Commelina dianthifolia - has three petalled, 1" gentian blue flowers in its first year, and then forms tubers to come back in the following year. Flowers all through Summer, and works well in borders, containers, conservatories and rockeries.

Flowering
From Mid Summer TO Early Autumn
Dayflowers bloom from mid Summer to early Autumn
Propagating by seed
From Early Spring TO Mid Spring
Sow seed in mid Spring in a greenhouse. The seed usually germinates in 4 - 5 weeks at 20°C [164]. When they are large enough to handle, prick the seedlings out into individual pots to plant out in late Spring or early Summer, after last frost.
Planting
From Late Spring TO Early Summer
Harden the seedlings off in late Spring or early Summer by getting them used to outdoor conditions, putting the pots outdoors during the day for several days, gradually extending the time they are outside. Once hardened off, plant seedlings out in late Spring or early Summer, after the last expected frosts to a sunny site with well-draining soil.
Propagating by division
From Early Spring TO Mid Spring
It is very easy to divide the plants in Spring, digging up a plant and pulling it apart into smaller pieces. Just ensure each piece to be planted has at least one growing bud
