Smoking Gun Switch Grass: An Airy Tan Haze Behind Late Lavender
Save
Smoking Gun switch grass is a compact, upright clump of medium green leaves topped in late summer by big, open, airy clouds of tiny tan flowers. Those panicles take up more than a third of the plant's height, so the top of the clump looks like a soft, smoky haze over a tidy base.
It brings movement to a sunny garden just as lavender's main bloom is behind it, and it keeps that haze standing well into winter.

Why a grass belongs near lavender
Lavender beds can feel static once the flowers are cut. A few clumps of Smoking Gun behind them add motion: the airy plumes sway in every breeze and catch low evening light. Its green leaves stay green through the season rather than turning purple, then go golden tan in fall, a warm counterpoint to lavender's silver.
It is shorter and more upright than many switch grasses, about three and a half feet tall and two feet wide, so it fits the middle of a border without swallowing the lavender in front. Leave a little space between the two so the lavender gets full sun and airflow. The Companion Plant Planner helps with spacing.
One flexible grass
Unlike lavender, switch grass is not fussy about soil. It grows in sand or clay and handles drought once established, but it also tolerates wetter spots and even rain gardens. That makes it useful at the low end of a lavender planting where water collects after storms: the grass takes the damp corner, and the lavender stays on the high, dry ground. It also tolerates salt.
Care through the year
- Spring: cut back to a few inches. It is a warm-season grass and starts growing late, so be patient.
- Summer: it grows fastest from early summer on. Water young plants in dry spells.
- Late summer: enjoy the smoky plumes from mid-August.
- Fall and winter: leave it standing for structure and bird cover. Its sturdy stems stay up unless snows are heavy.
- Disease: rust is the main issue in humid summers; airflow helps.
Cutting and drying
The plumes are good for both fresh and dried arrangements. Cut stems once the panicles are fully open and pair them with dried lavender for a soft, natural-looking bundle.
Format
Smoking Gun is offered as a full 72-cell plug tray, ideal for screening, mass plantings and growers. See the product page for current availability.
