The introductions are from Vale Royal Horticultural, specialists in primula breeding. They are all available in garden centres across the UK from now, in a 1L pot RRP £3.99.
Blackberry Ice has purple and white streaked flowers, Cherry Blossom has cherry pink coloured flowers, Clotted Cream has white to cream frilly flowers and Firecracker has streaked flowers in shades of red, orange and yellow.
With Mother's Day on 14 March, the mild winter could mean primroses may be over by then, say some growers.
Vale Royal Horticultural’s Dave Wales said: "Certainly the mild weather has brought crops forward. January could well be OK but any later maybe will be short."
