Petunia

Colorful non-edible flowers for bright indoor decor in an indoor smart garden.

Petunia is for readers who want the indoor smart garden to brighten a room rather than produce food. Its flowers add color and a soft decorative touch, making the garden feel more like a living centerpiece.

Petunia is not edible, so keep it separate from harvest-focused herbs and greens. It is best grown for color, fragrance, and the simple pleasure of seeing flowers indoors.

Remove faded flowers and tired leaves to encourage a cleaner display and longer blooming. It is a low-effort way to add seasonal color indoors.
