A very large Octopus Agave, Agave vilmoriniana, was donated by our neighbor, Rudy Schmidt,  a  retired botany professor at U.C. Berkeley. We planted it out on the lookout as a replacement for  the invasive Acacia baileyana trees that have been doing their job to stop the steep slope at the lookout from eroding, but when allowed to flower and go to seed they spread throughout this area of the garden.
