Habit of Sabal seedlings

[Phoenikakias]

From right to left Sabal bermudana, causiarum, maritima. All germinated at same time and growing under identical conditions. At first maritima seedlings had much slender and shorter strap leaves than causiarum, and were additionally very glaucous, almost as blue as the S uresana.  With age maritima  however tends to catch up causiarum in size and leaf color becomes greener, similar to causiarum. Only noticeable difference now is that leaves of maritima are slightly stiffer in texture. Could someone, growing maritima from seed on, confirm this habit of the sp in the very early stages of growth?
