Discovered at an old abandoned North Carolina residence, 'Primrose' makes a fast-multiplying clump. The flower spikes are in bloom throughout midsummer with soft yellow flowers delicately striped reddish-brown in the throat. Hummingbirds will be delighted that you planted it as they dive into its sunny maw. Ships when dormant.
