A theme for plant shops, built around a light finder that matches plants to the window they will live by.

Shoppers pick which way their window faces, then drag a potted plant across a photographed room. The light level, an approximate reading in foot-candles or lux, and the list of plants that suit that exact spot update as they move. The daylight model, window notes and distance unit are theme settings, and each plant's light range, care level and pet safety come from product metafields that the theme sets up on install.

The same light and care data appears on every product card as a four-bar light meter and a three-step care mark. Collection pages add light, care, pet-friendly and in-stock filters. Product pages show where the plant grows well by window direction and distance, along with care notes, a plant story and plants that suit the same light.

Planters work alongside plants on cards, on the product page, on the home page pairing section and in the cart drawer. Shoppers choose the grow pot or a planter, and the theme adds the plant and the planter to the cart together.

International selling uses the platform's own localization: a country and language chooser in the header, menu and footer, a first-visit country suggestion, prices in the local currency, a "where we deliver" page built from the store's countries, and country notes that the merchant writes for each market. Product pages show which country an order ships to, and the cart flags any item that cannot be delivered there.

Fern includes three styles (Fern, Glasshouse and Terracotta) and 41 sections, with templates for every page type, a password page, and shopper and editor text in English, German, Spanish, French and Italian.
