The Cal Poly Miniature Rose has about the brightest yellow color of any miniature rose!
The bright yellow color is very long lasting. The little pointed buds open to lovely double flowers that once fully open reveal golden stamens. The brilliant color of the Cal Poly mini rose makes it a standout in the garden.
There is a faint scent of clove to the high centered blossoms. (Some report no scent at all) You won’t find many thorns on this rose; it is (almost) thorn-less.
