That sounds so peaceful! I’d love to help you pick some plants that feel like the sea. Think of soft, silvery leaves like silver eucalyptus or silver fern—those look like driftwood against a wave. A little lavender or rosemary adds a hint of sea‑air scent. If you want something that’s literally blue, try a tiny blue flag iris or a blue‑leaved coleus; they’ll pop against your watercolor waves. Maybe sprinkle a few shells or a tiny seashell jar among the plants for extra ocean vibes. You could even add a small pebble or a tiny glass bottle with a sea‑foam color inside—just imagine the light catching on it while you paint. Hope it brings you calm and inspires your art!
