Primula veris is a semi-evergreen perennial plant, up to 10 inches (25 cm) tall and wide, with a rosette of leaves up to 6 inches (15 cm) long and up to 2.4 inches (6 cm) wide. The deep yellow, bell-shaped, fragrant flowers are produced in spring, in clusters of up to 30 blooms, together on a single stem. Each flower is up to 0.6 inches (15 mm) in width.
How to Grow and Care
Potted indoor Primulas are a delightful way to usher out winter or welcome in the spring. They are available in a wide range of striking colors, forming a mass of flowers. Most people prefer the taller, upright delicate Primulas indoors, but even a pot of common Primula is a nice addition. Extend the flowering season by pinching off dying buds. After the plant has done blooming, consider moving it outside. While inside, do not overwater; wilting even though the plant is getting water is a sign of root rot.
It's unlikely you'll be repotting your potted Primula. If you do, make sure not to bury them too deep—burying too deep is a prime reason Primula succumb. Bury the plants so the top of the root ball is slightly elevated above the level of the surrounding soil. Never pile soil up around the stem of a flowering plant.
They are propagated from seeds which are sown directly in soil or potting media. Most pots of indoors Primula are purchased as flowering plants, destined to be set atop a desk, sill, or table until they're done flowering… – See more at: How to Grow and Care for Primula.
