The family we lived with last summer had tons and tons of Zinnias planted with their garden (post here). This spring, during a visit, Rose (the matron of the family) pulled out a huge bag of zinnia seeds she had gathered from last year's flowers and gave it to me. She told me how to plant them, and I eagerly spread them throughout the garden. They've started to bloom and are so cheerful! I gathered a bunch and set them on the kitchen table.
