Method and Management of Primrose Flower Cultivation
Let's talk about the cultivation methods and management of primrose flowers and share some small green plant maintenance tips to help you easily master the secret of blooming. Detailed introduction is as follows.
Primrose flowers, also known as Yingsha, egg yolk, or bumblebee, belong to the Oleaceae family, Jasmine genus, and are upright or climbing semi-evergreen shrubs, 0.4-3 meters tall. Young branches are brown or yellow-green, the current year's branches are grass-green, twisted, quadrangular, and hairless.
Primrose leaves are alternate, compound leaves with 3 or 5 small leaves, rarely 7, and single leaves are often found at the base of young branches; petioles are 2-10 millimeters long; leaf blades and small leaflets are shiny on the upper surface and often have transverse wrinkles when dry, hairless on both sides, rarely pubescent along the midrib; small leaflets are ovate, ovate-elliptic to elliptic, rarely obovate or suborbicular, 0.7-3.5 centimeters long and 0.5-2 centimeters wide, with acuminate apex, mucronate, rarely obtuse or rounded, cuneate or rounded base, midrib sunken on the upper surface, convex on the lower surface, lateral veins not obvious; apical small leaflets are often slightly larger with petioles, 0.2-1.2 centimeters long, lateral small leaflets nearly sessile; single leaves are usually broadly ovate, elliptic, or suborbicular, 1-2.5 centimeters long and 0.5-2 centimeters wide.
Method and Management of Primrose Flower Cultivation
Primrose flowers form corymbs or umbellate corymbs with 3-25 flowers; bracts are conical, 3-7 millimeters long; pedicels are absent or up to 2 centimeters long; calyces have 5 prominent ribs, hairless, with a tube 1-2 millimeters long, lobes are acuminate-linear, 1-3 millimeters long; corollas are yellow, nearly funnel-shaped, with a tube 0.9-1.5 centimeters long, lobes are ovate or oblong, 4-8 millimeters long and 3-5 millimeters wide, with acuminate apex, rarely obtuse, margins puberulent.
Fruits are oblong or globose, 5-10 millimeters long and 5-10 millimeters in diameter, turning black when mature.
