A very low ground cover (5 in. by 20 in.) blanketed in bright clear yellow flowers.
Perennial — overwinters in climates without hard frost (0 to -10 degrees).
Use 'Citrine' as an edger in any border with a warm color scheme. Or, if growing as an annual, make it the first row in an all-coreopsis scheme, backed by 'Rum Punch' and 'Autumn Blush'.
