This other specimen looks recently planted.
Here's the third, the smallest:
A few weeks ago, we saw several recently planted specimens of Aloe suzannae at the nearby LA arboretum. Here's one:
And here is one photographed at the San Diego Botanic Garden last November:
Aloe suzannae is endemic to the island of Madagascar, and is near extinction in its native habitat. It is a solitary, non-offsetting, slow growing Aloe. In addition, it doesn't bloom every year, limiting availability. Thus, when I saw one for sale on Ebay, I jumped.
Unfortunately, as you can see, something is wrong. This top-down yellowing began to appear just a couple of days after it arrived. I contacted the seller, who was baffled and immediately issued a full refund without my even asking (Thanks!). A local expert thought it looked like light frost damage--could that have happened in transit? It's been very mild here, neither hot nor cold. If it survives--I'll have a relative rarity. If not, I have...a blog post. Such is gardening.
So, what Aloes were blooming at the Huntington at the end of May? A few. This one--no label. Possibly sinkatana.
Although this is a flower stalk, these are not flowers. This is an oddity--an Aloe that produces bulbils--appropriately named Aloe bulbillifera, from Madagascar. I include it, because...it's cool.
Aloe 'Caesia'--one I am unfamiliar with. A quick search mentions a 'Caesia' as a "variety of striatula - found only around Molteno in the Eastern Cape of South Africa".
Aloe porphryostachys. This is a solitary Aloe from Yemen. It is closely related to one I have, Aloe pseudorubroviolacea, and the flowers are somewhat similar. The plant, however, is an upright grower and is not as beautiful as pseudorubroviolacea, which drapes gracefully from sheer cliffs along the Red Sea.
Aloe tomentosa boasts flowers unusual for Aloes--they are fuzzy.
The fuzzy coating gives them a frosted effect.
