The Safflower in Chapter 22:Tamakazura: The Tendrill Wreath
The safflower's value as spice is nearly nil, but their staining capability justifies usage in the kitchen. Is said to have not that much flavor.

The characteristics of the flower is very simmilar to that of Suetsumuhana's.
1.One could conclude that her value to Genji is nearly nil-yet "Compassionate regard for Her Highness of Hitachi's rank prompted him to treat her for forms sake as well as he could"(436).Genji finds her manner to be drab or at least shikibu does "Dull or not she replied with a smile [to genji]"(436).
2. Of having no flavor like the Safflower:
She's wearing a willowrobe that Genji had givern her, that is in disasterous condition made of willow. "She had it on over a dark and lusterous layering, crackling starched, and she looked pathetically cold"(435)
*"The marvelous hair of her youth had suffered through the years, until he was obliged to avert his eyes in sorrow before a profile whiter that any pool below a waterfall" (435)
3.The flower has staining power justifies usage:"Only the colour of her nose shone undimmed through the mists"
*"Her meekly trusting faith in his loyality was certianly touching. Poor thing he said to himself in this rare moment of concern for her, even in things like this she is eccentric" (436)
