Prairie zinnia is a compact, mounded perennial flower with thin, needle-like leaves. This native plant is especially valuable for its heat and drought tolerance.
Even more, it blooms from mid summer through fall, constantly producing bright yellow flowers which turn into papery seeds. It grows best in hot sunny areas with well-drained soil.
Prairie zinnia has proven to be one of the most heat and drought tolerant perennial flowers at the Xeriscape Demonstration Garden. The continual production of bright yellow flowers is amazing. It makes a great filler plant among other perennials and shrubs in very low water areas.
Prairie zinnia stays dormant late into spring. It is one of the latest plants to green up, but its spectacular show is worth the wait.
Remove old plant material in spring before new growth starts.
