Aloe dhufarensis, above, has grown considerably. Native to Oman, on the southeast of the Arabian peninsula, it prefers fierce heat and little moisture. Though my garden cannot provide Omani temperatures, reflected heat from nearby concrete seems to satisfy this Aloe. Should we ever get a rainy winter, protection from rain may be necessary. I've watered this plant once or twice since purchase back in April 2015, plus it received around nine inches of rainfall since then. Not much!
Here it is a year ago, much smaller, at the bottom of the red circle:
Wow, a lot of growth on all the plants in just one drought year!
Aloe microstigma, long suffering on the same front slope, recently got its own irrigation dripper. It improved in health immediately, greening up and growing new leaves. Despite a reputation for preferring extreme dryness, the dryness of the front slope is--beyond dry. Aloe microstigma needs more water here than Aloe dhufarensis.
Native to the far different climate of New Zealand, lovely Hebe foliage seen recently in Santa Cruz. The new foliage, lighter than the mature, creates a contrasting effect of considerable charm.
And Agave marmorata, always a favorite in color, texture, and architecture.
