About Primulas
The Latin term primus means first and is appropriate for the name of this genus. Primula, primrose or cowslip, as they are called, are the early harbingers of spring and they work nicely with flowering bulbs. P. Polyanthus Group are hybrids crossed between various hardy primroses. Plants are low growing, 8 to 12 inches wide rosettes of leaves with a central cluster of showy flowers generally with yellow eyes. They bloom anytime it is warm from November to May.
How to care for your Primulas
Try to plant your primulas as soon as possible. If you are not transplanting immediately, make sure to keep the soil moist to the touch. Keep plants away from direct sun.
Where do I plant my Primulas?
These are adaptable plants, but all require shade during summer months. Primulas are happiest in moist, humus-rich, well draining soil in light to shady conditions. Some species, like P. japonica and P. denticulata require moist to boggy soil. Mulching for winter in northern climates is essential, especially if snowfall is unpredictable. In southern climates consistent moisture is a ‘must’ plus protection from afternoon sun. The conditions under which the various 400 species are grown are so diverse that your garden will probably have an environment for at least one primula species. Check the garden conditions recommended for the variety of primula you purchased.
How do I plant my Primulas?
Plant in a hole that is twice the size of the primula’s container. Incorporate some rich compost into the planting hole. Place the primula in the planting hole so that the plant is even with ground level and firm the soil around the primula. Water the plant well, making sure the roots are wet. Keep the primulas watered regularly. Mulching around the plant will help keep it cool and moist.
What should I do in order to have my Primulas increase in beauty year to year?
If you keep in mind that primulas thrive in cool climates, following the above mentioned planting directions should help ensure success. Primroses seldom need dividing, but if the clumps become too large, dig them as soon as possible in early spring. Applying mulch both spring and winter is suggested.
