Other info. - The first sighting
of Podophyllum leaves is a good indicator that spring
is arriving as the plant is one of the first to bloom in the new year.
The flowers only last a day or two. The fruits develop slowly and become
ripe around August. The fruit is edible when ripe and can be eaten raw,
but it is better when cooked. The leaves, stem, and rhizomes of the plant
are toxic. The plant was used by indians to treat parasites, syphilis,
jaundice, and other ailments. Recently, synthetics of the plants substances
have been used in cancer research. Some people have allergic reactions
to handling the rhizomes as they contain the allergenic compound Podophyllin.
The description above is for form
peltatum. Another form, form deamii
Raymond, has pink to purplish petals, a deep purple ovary, and maroon
fruits. This from is rare.
