Titan Arum
General Description
This gigantic, summer-growing plant from Sumatra has perhaps the largest inflorescence and tuber in the plant kingdom. In late spring, if the female plant is old enough, a thick, tall flower stalk emerges and unfurls a multicolored spathe and spadix with a rotting, foetid stench. It is pollinated by flies and carrion beetles. In summer, an immense leaf stalk reaches skyward with a huge, umbrella-like leaf that is very lobed and attractive.
This singular plant needs a warm, alkaline, well drained soil that is moist in the growing season but markedly drier in winter. It is a celebrated specimen plant of conservatories and plant collectors.
