Exclusive. 5-6" tall x 14-16" wide. Big yellow flowers and silver foliage on this compact, semi-dwarf Evening Primrose selection make it an exciting variety for small spaces. Drought resistant/drought tolerant plant (xeric).
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low
temperatures; the lower the zone number the colder the winter.
If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will
survive the winter temperatures in your area.
If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack
of freezing winter temperatures do not provide a time for winter dormancy (rest).
5-6" tall x 14-16" wide. Big yellow flowers and attractive silver foliage on a compact plant make Oenothera macrocarpa 'Dwarf Silver' a welcome addition to even the smallest garden bed. Maturing to half the size of the typical Evening Primrose, this new introduction is a tough, long blooming, waterwise perennial that will provide years of garden beauty.

Oenothera (Evening Primrose) - a huge genus of biennials and perennials native to the Western hemisphere. Flowers are in shades of yellow, pink and white. Pollinated primarily by hawk moths. Flowers open in the afternoon and close by late morning the next day.
Preferred growing conditions
Plant in low fertility ("lean") soil including dry clay, positioned in full sun. Mulch with gravel or not at all.
Water regularly the first growing season to establish the plant. Thereafter, infrequent but deep watering is all this plant needs.
Deadheading is not needed as these are naturally long blooming species. Fertilize lightly in the fall with Yum Yum Mix.
Special comments
Oenothera are tap rooted plants and does not like to be transplanted once established. Don't divide as they resent having their roots disturbed.
Leave standing over the winter and cut back hard, leaving 2 to 3 inches of stems above ground.
O. speciosa 'Rosea' is a showy everblooming species that can spread aggressively and should not be planted into areas where it's enthusiastic nature can be a problem. Deadheaded to reduce reseeding. Dig out suckering roots when spreading too wide.
Watch for flea beetles (small metallic green beetles) which can defoliate the plants in late spring/early summer.
