This plant is a wonderful silver-leaf version that looks very similar to the common green leaf Oenothera macrocarpa and grows in similar situations. The light and bright lemon colored blooms are stunning with the silver leaves. It is a strong grower when situated in a well drained gravelly soil in full sun. It looks great spilling over a wall where the large blooms can be appreciated up close.
