Common name: Julia's primula and sibthorp primula
Family: Primulaceae
Leaf:
P. vulgaris subs. sibthorpii: has a rosette of obovate leaves, very rugose, crenate margins
P. juliae: rosette of obovate leaves, also rugose, with crenate margins
Flowers:
P. vulgaris subs. sibthorpii: scapes of long- stalked, 5 petaled, trumpet-like, rotate, purplish-pink to white flowers 2-3 cm wide in early spring. Yellowish staining near inner circle creates an inner yellow ring- this inner yellow ring is distinctly larger than that of P. juliae's.
P. juliae: stakes of long-stalked purple flowers blooming in early spring. Inner yellow circle much smaller that P. vulgaris
Habit: clumping, herbaceous to semi-evergreen perennial; Form: mounding, can be matting
Height: up to 15 cm tall
Culture: Plant in dappled shade in moist, average to rich-loamy soils. Likes acidic soils- good to plant with rhododendrons. Primulas need moisture in summer. Tolerates full sun, provided there is moisture. Self-seeding. Hardy in USDA zones 4-9.
Uses: containers, borders, under-planting in a perennial garden.
Origin:
P. juliae: eastern Caucases
P. vulgaris subs. sibthorpii: Balkans
