Are primula auricula hardy?
Auriculas are perennials that include the show and alpine types with their almost artificially perfect flowers. These are hardy in a cold winter throughout the UK – can withstand temperatures down to -15°C (5°F), but do need shelter from rain and summer sun in an alpine house and are best grown in pots. During winter (end of November to second half of February) Ensure plants enjoy ample ventilation and protection from winter rain. Do not attempt to keep them frost-free. A cold greenhouse is the usual place to keep auriculas in winter and spring to protect the plants from wet weather and for the comfort of the grower.
What is the difference between primroses and Primula?
The primrose is distinguished from other species of Primula by its pale yellow (in the nominate subspecies) flowers produced singly on long flower stalks which are covered in rather shaggy hairs. The flowers open flat rather than concave as in the case of Primula veris, the cowslip. February is the perfect time to start adding colour to your garden or patio. And the beautiful Primrose is a fantastic choice to do so! The Primrose (Primula) is a herbaceous perennial plant, which means it has soft, non-woody stems that die back to the ground each year and regrow from the roots in the spring.There are a total of 500 primrose species, which are in flower from February to May. Candelabra primroses (Primula bulleyana and Primula bullesiana-hybrids) even bloom from June to July. The single, double or frilled flowers are rarely solitary.The most common colors of primrose blooms are purple, white, red and pink. Primrose blossoms have yellow centers with bi-colored petals. Petals are red, blue, yellow, white and many shades in between. Primroses can be grown indoors or outdoors, from starter plants or from seed.Most primroses and primulas need moisture-retentive soil and partial shade – some are more tolerant of sun. Deadhead spent blooms or let seeds develop so they can self-seed around your garden. Divide congested clumps every few years to rejuvenate them.
What is the common name for a Primula?
Primula vulgaris, commonly called primrose, is a semi-evergreen, rosette-forming perennial that is native from southern Europe to western Asia. It prefers woodland clearings, hedgerows and grassland habitats. Primroses are low-growing plants with rough, tongue-like leaves. These grow in a rosette. Their flowers are large and creamy and have deep yellow centres.Most types of primroses available here are hardy and, like the common primrose (Primula acaulis), can withstand sub-zero temperatures at times. However, other species such as the German primrose (Primula obconica) must move immediately to a protected location when frost occurs.However, during prolonged periods of frost below -5 ° C primroses should be covered. For this purpose, a layer of brushwood, leaves, moss, bark mulch or spruce branches is suitable. Alternatively, you can dig up the primroses, plant them in a pot and overwinter at home or in the gazebo.Primroses are very easy to care for. Simple pruning, with deadheading as needed, will suffice. Cut them back in late autumn, when the foliage has died, to encourage maximum growth in spring.
What to do with primulas when they have finished flowering?
Primulas can also be propagated by division. Simply dig them up after they’ve finished flowering, and separate the plantlets from the main plant. Plant these divided sections back in the ground where you want them to grow, and water thoroughly. During dry spells, water primroses regularly, providing about an inch of water per week. Water container-grown plants whenever the top inch of soil feels dry. In hot, dry summer weather, plants may go dormant unless they are kept well-watered.Water generously. These are water-loving plants and require moist soil to stay lush and firm. Check the pots daily and water primroses as soon as the soil begins to dry out or the plants will wilt, but do not leave them waterlogged or the roots may rot.A regular mulch can help keep in humidity and feed the plants. Primroses are easy to grow in pots, troughs or other containers in partial shade. For best results use a general purpose compost and keep the containers well-watered.Primroses are easy to grow in pots, troughs or other containers in partial shade.

Do you cut back Primula leaves?
A simple task, but a surprising number of people are unsure how to deal with their spring flowered primroses now that we are in mid-summer (says she, with wry face, looking at the rain streaming down the window pane). The answer is simply to chop them right back! Dividing: Over time, primrose can become crowded and benefit from division. Divide the plant in the fall or early spring, and replant the divided sections in well-prepared soil. Winter care: In cold climates, mulch around the base of the plant with straw or shredded leaves to protect the roots from freezing.
