|I found some potted Primula at the nursery today. Are these the same perennials as hardy primrose or are they a more tender annual? The lady there did not seem to know.|
|"Primrose" is the common name attached to some species of Primula. Most commonly cultivated species are hardy at least to USDA Zone 5, so yours should be happy in Oklahoma. More tender species, hardy only to zone 8, are P. malacoides and P. obconica. You can plant your primrose in part shade
after danger of frost has passed. Keep soil moist when the heat of summer sets in. Enjoy!
