Here is a list of plants that will make your garden a hit with the insects described above. After each plant, I listed the zones they'll be most comfortable in. This is a general guideline- many plants can tolerate more or less cold or heat, depending on the variety, so the rules aren't set in stone. If you're like me, and live in zone 10, but want a zone 9 plant in your garden, try planting it(maybe not in direct sun) and see what happens. Some plants can tolerate climates a bit beyond their suggested zones. For best results, find out the plant's sun, soil and water requirements and plant them in an area that suits them.
