Cinquefoil Crosses. Several strawberry cultivars with pink flowers are the result of crosses with another plant called a cinquefoil (Comarum sp.). One of these varieties, called Pink Panda (F. Frel Pink Panda), grows as a bushy, compact plant and has bright pink, yellow-centered flowers about 1 1/2 inches in diameter beginning in April. Another variety, Lipstick (F. Lipstick), has flowers that are a deep rose-red color, also borne on compact plants.
