Gardeners' Notes:

Positive palmbob On Dec 16, 2003, palmbob from Acton, CA (Zone 8b) wrote:

This is usually a solitary, eventually suckering, aloe that can get a lot of blue coloration... but if cool and full sun will sometimes have a green coloration with some red near the tips. It has a nice patina on it giving it the bluish color that can be rubbed off revealing the green beneath., and is relatively user friendly with only itty spines along the leaf edges. From Transvaal, Africa. Whoever listed this as blooming mid summer, must be from somewhere else than California. Here in blooms mid winter, sort of a rust-orange, dense bottle-brush like flower. Flowers are particularly striking on a solitary to only somewhat branched inflorescence, with the flowers all starting out a deep red, but then, just as they open, turning abruptly to a yellow-gold or a white color with green stripes. This color change starts at the bottom of the raceme and progresses slowy to the very top of the inflorescence. Plants looks great either as solitary specimens, or planted in large groups. One of the better non-stemmed aloes for southern California tolerating extreme heat and drought quite well.
