If you want to know how cold-resistant the Primula flower is and the correct cultivation methods for green plants and flowers, let's take a look together.
Primula, also known as Yingsha, egg yolk, and Niuxizi, belongs to the Oleaceae family, Jasminum genus, and is an upright or climbing semi-evergreen shrub, 0.4-3 meters tall. Young branches are brown or yellow-green, the current year's branches are grass-green, twisted, four-angled, and hairless.
Primula leaves are alternate, compound, 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 glossy on the upper surface, often with transverse wrinkles when dry, hairless on both sides, rarely pubescent along the midrib; small leaflets are ovate, ovate-elliptical to elliptical, rarely obovate or suborbicular, 0.7-3.5 centimeters long, 0.5-2 centimeters wide, apex acuminate with a small tip, rarely obtuse or rounded, base cuneate or rounded, midrib sunken on the upper surface, convex below, lateral veins not obvious; terminal 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, elliptical or suborbicular, 1-2.5 centimeters long, 0.5-2 centimeters wide.
How cold-resistant is the Primula flower
Primula has corymbs or umbellate corymbs terminal, with 3-25 flowers; bracts are conical, 3-7 millimeters long; pedicels are absent or up to 2 centimeters long; sepals have 5 prominent ribs, hairless, sepal tube is 1-2 millimeters long, lobes are conical-linear, 1-3 millimeters long; corolla is yellow, nearly funnel-shaped, corolla tube is 0.9-1.5 centimeters long, lobes are ovate or oblong, 4-8 millimeters long, 3-5 millimeters wide, apex acuminate, rarely obtuse, margin with cilia.
Fruit is oblong or spherical, 5-10 millimeters long, 5-10 millimeters in diameter, turning black when mature.
