Before hitting the Berkeley Horticultural Nursery, we found a larger than life succulent gem. OMG, this Century Plant (Agave americana var. marginata), was the size of a VW Bus. How appropriate for Berkeley.
I get a little confused with some of the variations of the Agave americana. After a little poking around, it seems that both var. marginata and var. variegata both have yellow to white coloration on the margins, but the var. marginata has a deeper green leaf center. One great source describing some other variations is San Marcos Growers. BTW, this site is chock full of info on ornamental plants grown here in California.
Cactus Jungle has a great pic of another A. americana v. marginata over in Berkeley.
If you peek just over the top of this succulent monster, the neighbor has a sweet dry garden too. Looks like some older Aloe arborescens and some columnar cactus.
Reminiscing about Agave flower spikes, I wish I could have seen Rancho Reubidoux’s Agave potatorum in full flower. Amazing how these smallish succulents and pop out such a display.
