Purple is one of the most common colors among U flowers.
- Uraria Crinita
- Upland Ironweed
- Upland Larkspur
- Utricularia Sandersonii
- Utricularia Dichotoma
- Upright Clematis
Purple U flowers tend to attract pollinators like bees and butterflies more strongly than pale colored blooms.
Yellow Flowers With U
Yellow is another dominant color in this list.
- Ursinia
- Uvularia Grandiflora
- Ulex Europaeus
- Utricularia Vulgaris
- Uncarina Roeosiiana
- Upright Yellow Flax
Yellow flowering U species often bloom earliest in the growing season, making them useful for early pollinator support.
Perennial Flowers That Start With U
These U flowers return year after year without replanting.
- Uvularia species
- Uva Ursi
- Utah Penstemon
- Upright Clematis
