Sweet citrus scented bloomy goodness! Deliciously huge, 4" wide flowers appear en masse Spring through early Summer. Blooms open late in the afternoon & until morning, attracting night owl pollinators like moths. Petals age to pink over time. Foliage forms a cute & compact 8" high & 18" wide rosette with attractive lance shaped fuzzy leaves with funky scalloped margins. Native to the desert ranges from Southern California to Eastern Washington & Utah, Oenothera caespitosa likes poor dry well drained soil & heat doesn't bother it one bit.? Makes an excellent addition to any dry garden!
