Also known as a "Speckled Japanese Aralia", the Fatsia Spider's Web is a rare plant which shows off splashes and speckles of white variegation across its large, bushy, palmate leaves. According to what I've been reading, the variegation on its leaves will actually change with the season, and as the plant ages!
Water: Allow top inch of soil to dry, then water thoroughly. Remove any excess water to avoid root rot.
Light: This plant loves light. Does best in bright indirect light, but can handle direct light or lower levels of light too. (Although lack of light may lead to loss of variegation.)
Soil: Does best in loose, well draining soil.
Humidity: Prefers higher humidity. Mist occasionally.
Fertilizer: Fertilize once a month using a balanced liquid houseplant fertilizer.
Tip: Fatsia Spider's Web actually prefers cooler temperatures than one would expect from such a fancy-looking plant, but it actually does best in temperatures between 15° and 21°.
