Easily grown in average, medium moisture, well-drained soils in full sun to part shade. Prefers moist, humusy soils with good drainage, but tolerates moderately dry ones. Will grow in full shade, but best foliage color usually occurs in part-sun locations (at least 3-4 hours of sun per day). Provide good air circulation in hot and humid areas where crown rot is a problem. Divide plants if they become overcrowded. This low-growing bugleweed will spread in the garden by stolons (reptans means creeping) to form an attractive, mat-like ground cover. Plants may be cut back to the ground after flowering, if necessary, to rejuvenate the foliage. Large plantings may be mowed on a high mower setting to remove spent flower spikes and to tidy the appearance of the planting. Space plants 6-9” apart for prompt cover.
‘Mahogany’ is a stoloniferous, mat-forming, bugleweed that forms a dense ground cover in part-shade areas of the landscape. Plants typically grow to only 2-4" tall, but spread outward over time by stolons to 12-24" wide or more. Plants are semi-evergreen in the southern areas of their growing range and deciduous in the far northern areas. Tiny, shiny, short-stemmed, narrow, near black-burgundy leaves emerge in spring. As the cultivar name suggests, those leaves gradually turn into a deep mahogany. Two-lipped, bright blue flowers (typical mint family) bloom in spring (late April - June) on leafy spikes rising above the foliage to 6-8" tall. An established ground cover planting will discourage weeds and will tolerate light foot traffic.
No serious insect or disease problems. Crown rot can be a significant problem, particularly in the humid conditions of the deep South and in wet, heavy soils.
Excellent ground cover for part-shade areas of the landscape. Good for small spaces. Beds, border fronts, foundations and containers. Rock gardens. Path edgings. Site plants in areas where its spreading habit will not cause problems with other nearby plants.
