Primula acaulis ‘Danova Red’ (syn. Primula vulgaris) – This member of the Danova Series features large (1.5-2″ wide) dark red blooms with a sharply contrasting bright yellow eye. Primula acaulis are common winter bedding plants (usually available from Dec-March), although they can also be grown as houseplants in a cool room. Grows 4-5″ high by 5-6″ wide. Hardy to zone 5.
Primula acaulis ‘ORION Yellow w/ Eye’ (syn. Primula vulgaris) – This F1 hybrid is quite floriferous and features fragrant bright yellow blooms with a golden-orange eye. In fact, you find that all yellow English Primroses are fragrant (particularly on warm days) regardless of the cultivar. If grown outdoors you will have to deadhead the rain-spent flowers. Grows 5-6″ high and wide. Z5
Primula acaulis ‘ORION Rose Frost’ (syn. Primula vulgaris) – These cheery deep rose-pink flowers are finely edged in white with a bright yellow center, and really stand out on those dull winter days. When grown as seasonal bedding they tolerate full sun, although a part sun exposure is best in you are overwintering them as perennials. Grows 5-6″ high and wide. Zone 5.
Primuka acaulis ‘Danova Sky Blue’ (syn. Primula vulgaris) – The blooms of this bedding primula look like a Batik skirt with pale blue petals and slightly darker veining, contrasted by a lemon yellow eye. These make great additions to sheltered outdoor planters, but be careful not to wet the plant when watering as this will spoil the flowers. Grows 4-5″ high by 5-6″ wide. Zone 5.
Primula acaulis ‘Primera Wine Flame’ (syn. Primula vulgaris) – Something a little more elegant in English Primrose with white-edged burgundy blooms accented by a yellow eye surrounded by a white starburst. Although Primula acaulis can be grown from seed, the finished plants are usually so inexpensive that it’s hardly worth the effort. Grows 5-6″ high and wide. Z5
