I can see why these are also called thomsoniana semi-alba (depending on island) with its characteristic shape, rather flat appearing.
You beat me to it. Mine is budding. Got to love this species. Yours look more maroonish than mine (which is more reddish)- may be exposure.
The color is dark, but having to shrink the file to under 60kb it looks far away and you can't see the detail. I also have a couple albo's in bud and a couple still in spike (no buds yet). This particular plant has small spikes, about 16 inches, but the ones that are still in spike (no buds yet) are still growing strong at about 32 inches. I'll post them when they bloom.
