Moon orchid

Across from Gu Yue village, the clan closely cultivates a sea of moon orchids with blue and pink petals shaped like a crescent moon. Moon orchid is food for a lot of Gu, and that flower sea is the clan’s biggest cultivation medium. ^{ch. 4}

Gu Yue clan plants huge numbers of moon orchids in an underground cave beside its spirit spring. Flower Wine Monk once tried to buy the clan’s moon orchids with primeval stones at a fair price, then demanded three thousand stalks of moon orchids every week as tribute. ^{ch. 15}

Fang Yuan buys ten moon orchid petals for one primeval stone. Moonlight Gu requires moon orchid petals twice a day, morning and night, two petals each meal, four petals every day. Without special storage, moon orchid flower petals last only five days, so he buys a bag at a time. ^{ch. 23}

Mixing Intimate Grass into a meal lets Moonlight Gu fill up on one petal instead of two. Intimate Grass costs two primeval stones per catty, while moon orchid petals cost one primeval stone for every ten pieces, so the mix is more cost-effective. ^{ch. 39}

Without moon orchid petals, Moonlight Gu may undergo self-sealing: it hibernates, loses its blue glow, turns from transparent crystal into grey rock with a rock shell, and that crust can thicken into a boulder. Self-sealing is uncommon; most Gu that lack food starve instead of sealing. ^{ch. 40}

Fang Yuan buys moon orchid petals at Jiang Ya’s shop each time he needs them. ^{ch. 69}

A clan mission gathers permafrost decayed soil that is likely meant to fertilize moon orchid flowers in the underground cave. That fertilizer is covered on permafrost decayed soil. ^{ch. 88}
