Grammatophyllum Jumbo Grand (Gramm. marthae x Gramm. stapeliiflorum)

This hybrid has pendent inflorescences just like the stapeliiflorum parent, but they are much longer than in the parent species.  The flowers combine the traits of marthae and stapeliiflorum in a way that I find pleasing.  This is not a plant for the windowsill grower or those with limited space.
