This guide explores some of the best options, categorized for easier planning and selection, focusing on bloom time, size, and specific care needs.

This zone experiences average annual minimum temperatures between 30°F (-1.1°C) and 40°F (4.4°C). This means most frost is minimal, allowing for a wider selection of plants than in colder zones. However, even in Zone 10, microclimates exist, and some areas might experience slightly colder temperatures, so always check your specific location's conditions.
