HOGWEED (Heracleum Sphondylium, L.) 
The fruits split apart when ripe, and they are winged, and thus 
aided in dispersal by the wind, and, being semi-detached when ripe, 
they are easily blown away. 
Hogweed grows in different types of soil, being a sand-loving plant, 
growing in a sandy soil, or a humus-loving plant, and growing in humus 
in woods, and in sandy loam. 
Two microscopic fungi infest Hogweed, Puccznia pimpinelle and 
iE ’votomyces MACY OSporus.
