Gardeners' Notes:

This Evening Primrose is one of my favorite flowers. It is very carefree and the yellow color is very deep, one of the best yellows in the perennial garden. Dependable bloomer and prolific seeder for attracting birds. It will always have a place in my flower beds.

A hardy biennial or perennial that will grow in sun to partial shade, well drain, rich soil. Plants are hardy from Zones 3 to 10. Garden writer, Tina James, popularized this very delightful plant and according to rumor she hosted Evening Primrose Parties starring this beauty. You can host a Primrose Party this year and actually see the large flowers slowly open (like in time lapse photography) right before your eyes. I watched the bright yellow flowers begin to open at 8:10 PM and by 8:20 they were fully open. The blossoms exude a beautiful lemon-lily and honeysuckle blend perfume. This is one of the most pristine and freshest scents that your nose can inhale at any one moment. The plant grows to over 3 tall with hundreds of flowers over the summer. (FlowerScent Gardens)
