Culture

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 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.

Noteworthy Characteristics

‘Sparkler’ is a variegated bugleweed that forms a dense ground cover in part-shade areas of the landscape. Plants typically grow to only 3" tall, but spread outward over time to 12-18" wide or more. Tiny, narrow, dark green leaves (to 2" long) are splashed with creamy white. Plants are semi-evergreen in the southern areas of their growing range and deciduous in the far northern areas. Two-lipped, bright blue flowers (typical mint family) bloom in spring (late April - June). U. S. Plant Patent Applied For (PPAF).

Problems

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.

Garden Uses

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.
