Bright clear yellow flowers. Leaves have burgundy tints, especially in cool weather and red stems. Oenothera Summer Solstice spreads to form an attractive mass, but is not as invasive as other Sun Drops can be. Great choice for a mass planting in a hot dry area. Very attractive.

Oenothera General Information

Oenothera are spikes of colorful cup-shaped flowers that open with the new day. These colorful varieties make fine additions to borders and rock gardens alike. Avoid wet feet. Fills in rapidly so give it plenty of room. Not fussy as to soil type. Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Oenothera Plant Care

This trouble-free plant is tolerant of poor, dry soil and self sows readily. After flowering, can be sheared back by 1/3 and shaped for nice form in the garden. Can be divided in spring or fall every 4 - 5 years or as needed to control spread.

Plantable Pots

Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!

100% Guarantee

We offer a 100% unconditional guarantee for all our perennials to reach you in good condition and to grow. If you're not satisfied, we'll reship or refund immediately. Please don't hesitate to contact us if you have questions or concerns—we share your passion for gardening and want your new plants to thrive in your border!
