context_page_description: The garden pansy is a type of large-flowered hybrid plant cultivated as a garden flower. It is derived by hybridization from several species in the section Melanium of the genus Viola, particularly Viola tricolor, a wildflower of Europe and western Asia known as heartsease. Some of these hybrids are referred to as Viola × wittrockiana Gams ex Nauenb. & Buttler. For simplicity, the older name Viola tricolor var. hortensis is often used.
  The garden pansy flower is 5 to 8 centimetres in diameter and has two slightly overlapping upper petals, two side petals, and a single bottom petal with a slight beard emanating from the flower's center. These petals are usually white or yellow, purplish, or blue. The plant may grow to 23 cm in height, and prefers sun to varying degrees and well-draining soils.
context_section_description: Modern horticulturists have developed a wide range of pansy flower colors and bicolors including yellow, gold, orange, purple, violet, red, white, and even near-black (very dark purple). Pansies typically display large showy face markings. The Joker Series has gained the Royal Horticultural Society's Award of Garden Merit. 
  
  Plants grow well in sunny or partially sunny positions in well-draining soils. Pansies are perennial, but normally grown as biennials or annuals because of their leggy growth. The first year plant produces greenery, and bears flowers and seeds in its second year of growth. Afterwards, the plant dies like an annual. Because of selective human breeding, most garden pansies bloom the first year, some in as little as nine weeks after sowing. 
  Pansies are purchased as six-packs or "flats" (USA) of young plants from garden centers and planted directly into the garden soil. Plants will grow up to 23 cm (9 in) in height with flowers measuring 5 to 8 cm (2 to 3 in) in diameter, though smaller and larger flowering cultivars are available.
  Pansies are winter hardy in zones 4–8. They can survive light freezes and short periods of snow cover, but, in areas with prolonged snow cover, a covering of a dry winter mulch is recommended. In warmer climates, zones 9-11, pansies can bloom over the winter, and are often planted in the fall. In warmer zones, pansies may re-seed themselves and return the next year. They are not very heat-tolerant; warm temperatures inhibit blooming and hot muggy air causes rot and death. In colder zones, pansies may not survive without snow cover or protection (mulch) from extreme cold or periods of freezing and thawing. They perform best in zones with moderate temperatures, and equal amounts of mild rainfall and sunshine.
  Pansies, for best growth, are watered thoroughly about once a week, depending on climate and rainfall. The plant should never be over-watered. To maximize blooming, plant foods are used about every other week, depending on the type of food used. Regular deadheading can extend the blooming period.
