Description

The Mexican daisy is a mounding to spreading perennial with delicate foliage character, native to Mexico and south to Venezuela. It grows 15-20 in. high, 2-3 ft. wide; trimming in the winter can manage its size and renew its foliage character. Small flowers first develop white and then age to deep magenta resulting in a mixed color display. These flowers have yellow centers and cover the plant in spring and intermittently throughout the year.

Mexican daisy is a highly popular border and flowering accent plant for small garden spaces in both sun and partial shade. It can be planted as a ground cover, used to line the perimeter of garden beds, planted in pots and behind small retaining walls where it will cascade over edges. It is easy to grow in well-drained soils and moderate amounts of water throughout the year.

Water Needs

The Mexican daisy is well adapted to Inland Empire gardens. It grows best in areas that receive afternoon shade and a regular schedule of summer water. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months indicated by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water depending upon exposure conditions and temperatures.
