Quercus marilandica aka Blackjack Oak

Quercus marilandica, commonly referred to as the blackjack oak, is a small deciduous tree that is native to the eastern and central United States. It belongs to the red oak group Quercus sect. Lobatae and can grow up to 15 meters tall. The bark is cracked into rectangular black plates with narrow orange fissures, while the leaves are dark green and glossy above, pubescent underneath, and often remain attached to the twigs through the winter after turning colors from red to brown in the fall. The acorn is small and takes 18 months to mature. The blackjack oak grows in poor, thin, dry, rocky, or sandy soils where few other woody plants can thrive, usually on low ground, from sea level up to approximately 2,800 feet in altitude. Some commentators say that it does not have the beautiful form of many oaks, but is nonetheless a valuable tree for growing in problem sites. As a houseplant, Blackjack Oak is super rare and easy to grow with regular watering. It prefers long-lasting, direct light and should be less than 1 foot from a window. It likes well-draining soil and doesn't need added fertilizers if you repot each time it doubles in size. It belongs to the Quercus genus and is native to the Central and Eastern United States.
