Garden geraniums (Pelargoniums) are some of the longest-blooming annuals available — and unlike most annuals, you can overwinter them indoors for years.
Good companions: roses, marigolds, petunias
Avoid planting near: Overwatering — most common cause of decline
Ornamental; harvest scented leaves anytime for culinary or aromatic use
