Fantastic Design Plant: Rockrose

When heavens dry, don’t feel pressured to increase your watering program or risk losing the backyard.

Distinguishing attributes. A sun- and – heat-loving plant, rockrose produces a colorful and lush heaping ground cover or informal hedge. Cooling leaves and vivid flowers enliven arenas which may otherwise have been left barren.

Once recognized, rockrose will prosper with minimal or no care. Blooming profusely through summer and spring, it may also bloom sporadically throughout the rest of the year. Distinctly papery flowers range in shades from vibrant pinks to whites and lotions — typically with a bright yellow centre. When not flowering, rockrose creates a mounding texture of gentle gray-green leaves. The leaves of several species even emit a blossom resin when the warm summer sun beats down on them.

How to use it. Rockrose, unsurprisingly, is quite commonly used in rock gardens or at which there’s a prevalence of gravelly and rocky soil. Dry banks or slopes can be difficult backyard spots for both planting and soil stability, and those are regions where rockrose thrives. Additionally, its nice texture and informal form contrast nicely with gravel and rocks as a gentle and effective ground cover or low-growing hedge.

Cistus palhinae, zones 8 to 10,revealed in Cape St. Vincent, Portugal, serves as great inspiration for designing with this plant. Scattered throughout the landscape, the plants tie the space together, gently accenting and highlighting the terrain. Without dominating the backyard, rockrose gives an enjoyable and unique outdoor adventure throughout all seasons.

Planting notes. Rockrose is indigenous to the Mediterranean, preferring similar climates and conditions. Faring well in regions with dry, hot summers, many crops are hardy to 15 degrees Fahrenheit. This plant requires no additional watering and requires minimal maintenance once set up, so be sure soil is particularly well drained if you do irrigate.

While this plant doesn’t survive long, it is a fast grower. Stems may become woody with age, and the plant ought to be replaced when they become lean. Periodically cut back old stems so as to encourage new growth and keep the plant looking clean.
