flower, small, little, lush
芾 is a rare kanji whose meanings are not clearly unified. It can refer to a flower, something small or little, or lush vegetation. The conceptual center is uncertain, so treat these as separate senses.
The historical development of 芾 is uncertain. It visually combines the grass radical 艹 with 巿, but the original semantic and phonetic roles of these components are not clear.
The grass radical 艹 sits above 巿, which looks like a cloth or garment. Picture a small, lush flower blooming on a piece of cloth, representing both the flower and small/lush meanings.
For ヒ, imagine a tiny flower saying 'hee hee' as it giggles while growing lush on the cloth: 'hee' -> ヒ.
