Primrosa Plants

Has anyone heard of Primrosa Plants not sure if it is spelt correctly.My wife was told about them as they apparently grow quite tall and as I have cleared a area at the bottom of the garden as we had to replace some fence panels would like some tall plants to cover the panels.Any info appreciated.

 

I have given you the wrong name for the plant it should have been Primula the wife got it wrong.Do these come as bulbs or plants when is the best time to buy and plant them.I believe they flower every spring is that correct.
