Water Saving Tip:

Change spray sprinklers to low-flow bubbler or drip systems. Shrubs and trees are ideal candidates for this type of irrigation because the water is applied directly to the root zones.

  • Description

  • Notes

‘Purple Torch’ is a stoloniferous, mat-forming, bugleweed cultivar, with rosettes of oval, shiny, dark green leaves typically form a 3 to 5 inch tall carpet. Spires of lavender-pink flowers appear in spring that rise well above the foliage to 12 inches tall. Foliage turns bronze in winter. When in full flower, large plantings can produce a striking floral display.
Plant in part to full shade, though best leaf color occurs with some sun. Prefers rich, organic soils that are well-drained. Spreads rapidly by stolons and can be quite aggressive in lawns. Plants may be mowed on high setting after blooming in order to remove spent flower spikes and to tidy the appearance, though it isn't necessary. Goes dormant in winter and emerges in early to mid spring, depending on the weather. In shadier areas, it may require less-frequent watering.
