Night Blooming Cereus
The only way I can justify this as garden junk is for you to visualize the dead jumble of sticks this looks like the other 364 days a year. This Night Blooming Cereus blooms once a year and last night it had 49 - 4" flowers on it. By 11am this morning they will all have wilted away.
These pictures were taken at midnight and 6am this morning.
