Square Foot Gardening Guide: how to care for verbena

Gardening infographic titled "Square Foot Gardening". Archetype: HOUSEPLANT CARE GUIDE. Create a minimal flat botanical infographic in a warm earth & terracotta palette, adapted to a cool / Nordic climate, with botanically accurate plant forms and a cottage-garden aesthetic. Feature a neat square foot raised-bed layout as the main visual, with a small botanical illustration of verbena included as a supporting plant reference. Include 5-8 labeled callouts in English: grid spacing per 1 ft x 1 ft square, full sun needs, watering guidance, rich well-drained soil, cool-season planning tips, seedling/transplant placement, companion-friendly bed organization, and harvest/maintenance cues. Clearly label edible vs toxic plants where relevant. Do not include pesticide brand logos or any GMO recommendations. Keep the design clean, instructional, and visually optimized for the search intent of caring for verbena, but without rendering that search phrase as on-image text. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no watermarks Botanically accurate plant forms. No pesticide brand logos, no specific GMO recommendations. Edible / toxic plants must be correctly labeled where relevant.
