Rainy botanical greenhouse watercolor

Create a delicate watercolor illustration of a rainy botanical greenhouse in early morning. Landscape composition, transparent washes, granulating pigments, soft wet-on-wet blooms, visible cold-pressed paper texture. Scene: arched glass greenhouse ribs, raindrops streaming down panes, hanging ferns, orchids, clay pots, a narrow stone path, a wooden bench with an open gardening notebook, and diffused silver daylight. Palette: sage green, eucalyptus gray, pale lavender, warm terracotta, and tiny yellow flower accents. Keep the image airy and poetic, with preserved white paper highlights, no hard digital gradients, no photorealistic lens effects, and no heavy outlines.
