General description

Also known as Tickseed. Plants form a low mound of leathery green leaves, bearing many upright stems of large golden-yellow semi-double daisy flowers for many weeks, starting in early summer. Removing faded flowers regularly will encourage blooming to continue into the fall. This is a medium-sized selection that will not get overly tall or floppy. Plants are easily divided in early spring, and this should be done every 2 to 3 years. Tolerant of hot, humid summer climates. Excellent for borders, as well as in containers. Attractive to butterflies. Species is native to the southern USA.

Maintenance

  • Water the young plants, giving them half an inch of water twice a week for two to four weeks until they are established. 
After this point, they only need water during prolonged dry periods.
  • Deadhead the flowers every day while they are blooming. 
This will keep the plants blooming throughout the summer. Cut the plants back in midsummer if they become leggy.
  • Cut the plants back almost entirely to the ground in the late summer or early fall.
  • Divide the plants every three years in the early spring to promote new growth and to further harden the plant against cold temperatures.
