In the wild they do. After a year, the plants start to become extremely small and slowly die. You can see the process on that picture, the leaves start to become yellow white. After blooming, nothing will be left of most of them.
All of the wild anitum are very big plants but they are not cultivated properly. They grow on heavy metal soils.
Sounds like magnesium deficiency. (Or potassium overdose).
I looked up a plant description in Birk. Lists adductum as having 2-3 flowers, but "var anitum" as having 3-7 flowers. In some ways this reminds me of Paph philipinnense and var. roebellinii.
