Does anyone know how large an Amorphallus gigantum or "corpse flower" gets before it blooms?

Answer 1

Hi To You,
This is one site that tells all about the corpse flower, and there are several more listings, when I typed in corpse flower as a search word.

The spath of the one at Virginia Tech greenhouse reached 161cm height and 99cm circumference before it began to open on Aug. 6, 2006. It's a young one. Check their page for great photo diary and bio facts.
