Easy to grow and doesn't seed around. Overwintered in containers outside near Warsaw, Poland in 2011. Received the highest rating at MSU for container culture. The #1visitor favorite Coreopsis in 2012-15 at the Mt. Cuba trials.
Grow with 55 – 60° F nights and 60 – 70° F days. Pinch at transplanting. Obligate Long Day plant. Provide night interruption or day-length extension to force flowering under natural short days. Supplemental lighting during cloudy days has proven beneficial for flower production. For highest quality, bring in liners in fall to bulk for early spring sales. Received the highest rating at MSU for container culture.
A wow plant – so bright, so low, so compact, and so showy. 'Citrine' impressed us with how floriferous and clean it looked all summer long. The flowers appear right on top of the old ones which just disappear. Works well in mass, as edging, or in mixed beds or containers. Many months of exciting color. Low maintenance and easy to grow. One of our most popular introductions!
