苋 is most often seen as 苋菜, a leafy green eaten across southern China and Southeast Asia. The red variety bleeds purple-pink dye into rice and oil, a signature look in Cantonese and Taiwanese home cooking.
Top grass radical, three-stroke compressed form. Indexes 苋 as a leafy plant. 苋菜 is amaranth, a soft red-veined green eaten across south China. Same family of edibles: 菠 (spinach), 葱 (scallion), 蒜 (garlic).
Bottom 见 supplies the sound, jiàn drifting to xiàn through the regular j/x palatalisation in old Chinese readings. Pure phonetic role; the eye-on-legs picture of 见 contributes no meaning to this plant character. Same shift appears in 现 (to appear).
