Begonia Parviflora

Very late in the year, as daylight hours shorten, clouds of confetti-like flowers with prominent bright yellow anthers open, en-masse, atop the strong flower stalks. Because it only flowers when the weather is cool, if only in comparison to that of spring and summer, it is an impressive foliage plant during the warm months, with visual impact with its amazing leaf size and overall scale. As an annual in a warm climate, this astounding plant gathers strength all season, soaring to four or even six feet by frost. But in even warmer or hot climes, the "tree" begonia makes good on its name, with thick canes twelve feet (4 metres) high and more, each with a few enormous rhubarb-like leaves nearly a foot across, which are displayed loosely on strong, upright canes. So to guarantee a shower of flowers late in the year, try one in a large pot indoors in good light.
