Fragrant plants

The most fragrant plants include lavender, roses, mock orange, lilac, lilies, sweet pea, phlox, and herbs like mint, rosemary and thyme. Some scent the air with their flowers, others with aromatic leaves when touched. In the atlas the "fragrant" trait is tagged separately, so they're easy to gather into one list.

Night-scented stock, flowering tobacco, evening primrose, and some lilies and mock orange are most fragrant in the evening and at night. They release their scent after dusk to attract night-flying pollinators. Plant them near a patio, porch or under bedroom windows.

Some aromatic plants like lavender, mint, lemon balm, catmint and scented geranium release oils that mosquitoes dislike. The effect is modest, though, and works mainly when you crush the leaves, not from the plant's mere presence. Treat them as a pleasant addition rather than full insect protection.
