Oenothera macrocarpa ssp. incana 'Silver Blade'
Plant Details:
Plant Type: Perennial
Plant Family: Onagraceae
Plant Description: Similar to the species, this trailing perennial produces large, sunny yellow flowers from late-spring to fall. The leaves of this variety have a silver hue that makes them stand out in the landscape. They can be aggressive spreaders and can be easily cut back if they get too leggy.
Maintenance:
Maintenance Type: Perennial - Herbaceous
Plant Care: Perennial - Herbaceous (soft-stemmed plants that die back in winter and regrow in spring): Remove spent blooms to promote rebloom later. Some plants tend to flop over after the first bloom and attempt to regrow from the base; in these cases, the old stems can be cut away in summer. As plants become dormant in the fall, remove dead leaves and stems.
