I got an e-mail last Friday that read, in part,
. . . do you have an idea what the plant in the attached pictures might be? It was given to me by a friend, who is quite certain that the plant salesman described it as a haiacanthus, and that its Dutch name is poederdons ('powder puff'). However, a plant listening to these names (in any spelling variety) does not seem to exist in the internets.
The question was accompanied by five photos, three of which are below. They'll all blow up much larger if opened in a separate window.
As the e-mailer says, there's nothing by the name Haiacanthus on-line, nor did trying variations on the spelling help. The only similar flowers I could think of were for stuff like Acacia, Mimosa, and Calliandra, and they all have pinnate leaves, so I don't think that's the right neighborhood to be trying.
So I bring it to the readers. Does anyone know what this is, or know of any succulents or cauduciforms (it looks like a caudex-former to me, anyway) that have flowers like this? 'Cause I am completely stumped.
UPDATE: Has been identified as Haemanthus albiflos in comments. I would never have come up with that on my own in a year of Googling (though I did think at one point that maybe it could be in the Amaryllidaceae, because of the leaves, I didn't follow up on it), and now I want one. Added it to the want list in the sidebar and everything.
Thanks to Don, John de la Parra, and College Gardener!
