The vampirestalk (malus lugosi) is one of several new species introduced to Earth in late 2010.
The stalk grows approximately 40 centimeters high and has an elastic body which feels gelatinous to touch. With an intricate root structure running up to two meters deep, it draws water and nutrients from the soil quite aggressively and pumps them into the fruit. The plant thrives in dark locations - direct UV radiation has been found to cause damage on the surface.
The fruit is non-edible and hard at first, but the water softens and expands it over time to an grape-like form and consistency. After a few weeks, the fruit reaches the size of a pineapple and is heavy enough to bend the stalk enough for its water canals to be blocked. As the stalk begins to wither away, it eventually drops the fruit off .
