Begonia fusca is a rare species from southern Mexico with fuzzy leaves that are very big.  In fact, at 2 feet across, its leaves are one of the largest of all Begonia species!  This robust, rhizomatous Begonia grows 4 to 6 feet tall, sending up a beautiful flower stalk about 5 feet tall each autumn.  This is a striking specimen for rare plant collectors or Begonia fans.  I don't know any other source for fresh seeds on the internet.

Begonia fusca has upright-growing leaf stems, somewhat resembling a Gunnera plant.  The leaves are basically oval in shape, and have a great felty texture due to small hairs across the surface.  The younger leaves are especially fuzzy.  The plant flowers during the shorter days of autumn and winter, although it may bloom at other times when grown indoors.  Its thick flower stalk rises above the foliage and is topped with pretty blooms, as you can see below.  This is a true species, not a hybrid.  It has good breeding potential with other Begonias, and might make some interesting new hybrids!

Begonia fusca comes from mid-elevations in Mexico, where the climate is mild all year.  It has handled temperatures in the mid-80s (30°C), but it should be considered experimental in warmer conditions.  It reportedly can re-sprout from the roots in Zone 9, but i recommend protecting it from freezing temperatures.  It is easy to grow in a pot indoors.  It enjoys rich, well-draining soil that is kept moist (but not soggy).  A good soil mix is half potting soil and half perlite or fine orchid bark.  It likes filtered sun or bright shade + morning sun.  Protect it from strong afternoon sun.  Over about 40% humidity is recommended.
