Because the first root of a palm stops growing after it reaches a certain size, whereas the rest of the plant continues to grow. Therefore, the stem produces more roots, which reach for the ground and look like stilts. Stilt palms are much more than simply interesting plants.
Iemesls ir tas, ka pirmā palmas sakne, sasniegusi noteiktu lielumu, pārstāj augt, bet stumbra pamatne dzen jaunas saknes, kas, palmai augot, parādās virs zemes kā savdabīgi balsti.
