Plant Combination: Butterfly Weed (Asclepias tuberosa) and Threadleaf Coreopsis (Coreopsis Verticiliata)’ Zagreb’

coreopsis-asclepias combinationHeat up a sunny border in mid-summer with this sizzling combination of yellow and orange. The coreopsis is a golden yellow that seems to shine with inner warmth. The butterfly weed can vary in color from yellow to orange so search out the orange color to really make the combination pop. The coreopsis will bloom before the butterfly weed flowers appear and will continue to bloom long afterwards but while they bloom together, enjoy the vibrant combination. The round daisy-like coreopsis flowers contrast nicely with the fine textured the butterfly weed flower heads. More textural contrast is provided by the very fine foliage of the coreopsis and the coarse leaves of the butterfly weed. Both plants like full sun and dry to medium-moist soil that is well-drained.
