Ideal Sun Conditions:
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
