The garden pansy is a type of large-flowered hybrid plant cultivated as a garden flower. It is derived by hybridization from more than a few species in the section Melanium of the genus Viola, chiefly Viola tricolor, a wildflower of Europe and western Asia known as heartsease. For simplicity, the older name Viola tricolor var. hortensis is often used. Pansies are perennials but are short-lived in many areas and so are often grown as hardy annuals or biennials.
Hybrids come in just about in every color imaginable, many bicolored or tricolored, with the familiar faces that most people remember from their childhoods. Most plants are about 8 inches tall. They are used in window boxes and planters as well as in gardens. Like most gardeners, I find the spring pansy show a welcome sight, but boy, can they sulk in hot weather! Fortunately, most of them revive when it gets cool at the summer’s end, and there are all those little faces again. In mild climates, they willbloom all winter.
Now if you want to grow Pansy then it can be sown indoors 10 to 12 weeks before the last average frost, but be sure to sow them shallowly, keeping the seed tray dark, moist and cool. Transplant them into the garden in the spring in fertile, humusy, moist soil you should move them early enough so that they can establish good root systems before the weather gets too warm.
Moreover, a more reliable method is to sow seeds in the summer or fall for blooming the following spring. In cold climates, this is best done in a cold frame, though some gardeners have good results by mulching the seedlings heavily. Left to their own devices, a few pansies will often overwinter or self-sow, even in cold areas. Moreover frequent picking or deadheading will give you more compact plants and profuse bloom.
