With higher temperatures outside, the cycle of UW-River Falls’ “corpse flower” sped up, and the plant reached bloom stage last night. (See live video.)

This is the second time in three years that the titan arum, which gets its common name from the foul odor it emits, has bloomed in three years.

The plant is a large rare flower named for the stink of rotting flesh that is emitted as it blooms. The blooming cycle can span anywhere from several years to several decades with the bloom lasting only a few hours.

The corpse flower has been growing at the UW-River Falls since 2001 and opened for the first time in October 2010.

Monday morning Dan Waletzko, greenhouse and field plot manager, estimated the flower would open in the next few days if consistent with its past flowering. It reached a height of 48 inches late last week and slowed in growth over the weekend.

The flower's last outer sheath wilted on Sunday, according to Waletzko, and, if consistent with the 2010 opening, the flower would open about five days after the last sheath wilts. In 2010 the bloom only lasted 6-8 hours, from approximately 7 p.m. to 2 a.m., before it began to close.

The plant's rotten meat odor is strongest at night in order to attract carrion beetles and flies which pollinate it.

UWRF received the corpse flower seed from UW-Madison in 2001.

The video feed and more information about the corpse flower can be found under news and events on the College of Agriculture, Food and Environmental Sciences home page at http://www.uwrf.edu/CAFES/Index.cfm.

Visitors are welcome to visit the greenhouse to view (and smell) the flower. Regular hours are 8 a.m. to 5 p.m., Monday-Friday. Hours may be extended depending on interest and the time of blooming.  Large groups are encouraged to call ahead as viewing space may be limited.

The UWRF greenhouse is located behind the Agricultural Science building off South Third Street. For more information, email Waletzko at daniel.k.waletzko@uwrf.edu or call 715-425-4888.
