High and generally high map to recommend; medium, medium to high, and low to medium map to mixed; low maps to avoid. The collective ice-plants row explicitly names Carpobrotus, Delosperma, and Drosanthemum, so it produces three genus-level rows.

Its ratings are kept in the existing la-arboretum-tree because Radtke cites that plant-selection lineage and acts as a popularizer rather than a new independent taxon trial.
