Common Madia, or Madia Elegans, is in the sunflower or daisy family. The annual grows between 12 and 24 inches tall. The stems can be simple or branched, with soft hair toward the ground. They are sticky at the upper part of the stem. Unlike most sunflowers, the heads are smaller and have narrower petals. There are usually between five and 21 yellow rays or maroon disk flowers with black or yellow anthers that bloom between mid-summer and early fall. They have a strong scent.
Choose a planting site in the full sun. The best time to sow the seeds outdoors is in the fall.
Make small holes for the seeds. They only need to be about 1 inch deep and you can use a spade or your finger to make them. Space the seeds 3-6 inches apart.
Place a seed in each hole. Cover with soil and pack down.
Water the seeds every other day until seedlings appear. If you live in a more rainy climate, don't water as frequently. Common madia are drought-tolerant and should not be over-watered.
Expect more flowers to appear next year because the common madia self-sows freely. If you don't want volunteer seedlings to appear, cut or pinch the flowers off as their die. This is called deadheading.
