Question
How do you grow them?
How do you take care of them, and find out what type you have?

Answer
Patty,

If the primrose you are refering to is the native American biennial flower, then all you need to do is to plant them in full sun in well drained soils that is neutral. They should last for 2 years.

If there is another primrose or if that is only the variety, then let me know and I will try to find out more.

Good luck,
