Flora, a village flower vendor, wins an unexpected short-term job at the royal garden thanks to her remarkable gardening talent. While working, she uncovers mysterious silver lavender seeds that have lain dormant for years, and with careful cultivation brings the extinct wonder flower into bloom once more. From a market stall to the royal garden, she finds herself among the plants, and while holding true to her original intentions, she carries on the tradition of horticultural craft — writing a gentle, healing poem of growth.
