Abstract
A new and distinct cultivar of Chrysanthemum plant named Buttercup is provided. The new cultivar was the result of a controlled breeding program wherein the Cassa cultivar (U.S. Plant Pat. No. 6,103) was pollinated by the Ahrensia cultivar (non-patented in the United States). More specifically, the new cultivar forms attractive relatively small single intense yellow flowers having a yellow-green disc florets which change to yellow when mature (as illustrated). The inflorescence is pyramidal in configuration and tends to flatten upon maturity. The response period of the flowers is approximately seven and one-half weeks. The plant is both low temperature and high temperature tolerant. The new cultivar is particularly suited for use in the production of a cut single spray under greenhouse conditions.
