COLORBLENDS, part of Schipper & Company, is still family owned, and we still sell bulbs to some of the same customers Cornelis visited 50 years ago. What's new are Colorblends: pre-blended mixtures of tulips that combine two, three or more varieties for a jaw-dropping, car-stopping spring display. There is nothing wrong with a block of red or yellow, but the tapestry effect of a Colorblend takes tulips to a whole new level.
