Tricia Diggins of the Wellesley College Botanical Gardens in Boston told ABCNews.com that while it may be possible for such trees to grow without light, she doubted whether such an environment could yield an apparently normal, green plant.

While removing what he thought was a benign growth from a newborn's brain, Colorado physician Dr. Paul Grabb found that the growth contained a tiny foot, a partially formed hand, a thigh and another partially formed foot.
"It would be a shock to even the most experienced pathologist cutting into a tumor to see this," he told the ABC affiliate KMGH.
Grabb said he could not tell whether the miniature limbs were from a benign stem cell tumor called a teratoma or the remnants of an identical twin that did not split off and survive -- a condition called fetus in fetu.
