Rose of Sharon, or Althea, is another reliable old-fashioned garden plant well suited for the Texas Panhandle. My favorite cultivar is Diana because of the brilliant, pure white 4-5” flowers and somewhat glossy green leaves. Diana is also one of the smaller varieties up to about 6 - 8 feet, while others can reach 10’ tall. Similar to most altheas, 'Diana' is a prolific bloomer.

Rose of Sharon is versatile, able to flower equally well in full sun to part shade, and once established is a low water-use, low maintenance shrub. Althea belongs to the Malvaceae family, the mallows and hibiscus.

Use in Garden

Versatile low care shrub for sun or shade, low water to high water use bed or border.


Topdress with one inch of compost in spring and fall.
