Aloysia citrodora
Lemon verbena is a tender perennial herb that brings a strongly lemon-scented presence to sunny planting plans. At about 5 feet tall and wide, it reads more like a small, airy shrub than a low culinary edging plant. Use it where its foliage can be reached easily for summer-to-fall harvests, while leaving enough open ground for its broad mature form and nearby garden tasks.
Space Lemon Verbena 4 ft apart, measured center to center (1.2 m).
The mature spread is about 5 ft (1.5 m), so plants set at that distance grow together into a closed canopy over the bed.
Treat 4 ft as a planning baseline — cultivar and local growing conditions shift the final footprint.
Give lemon verbena a full-sun position near a kitchen-garden path, patio edge, or other regularly used route, but keep its center set back from the walking line. Its fragrant foliage makes a close-by position worthwhile, while its eventual size calls for room to approach it without brushing through neighboring plants. In colder areas, place it in a sizable container that can be moved for winter rather than committing a permanent bed space.[1][2]
Set plants 4 feet apart, center to center. Each plant can reach roughly 5 feet across, so this spacing allows the mature outlines to knit together by about 1 foot rather than remaining fully separate. Use a single plant as a substantial bed anchor, or repeat it on that 4-foot grid along the back or middle of a broad herb border. Keep the front open for lower plants and preserve a path-side reach-in zone.
Plan for full sun and moderate watering in a well-drained planting area. Avoid locating it at the bottom of a bed, beside a downspout, or in a pocket that stays wet after rain. A raised edge or container can make drainage and root-zone conditions easier to control where the native soil holds water.[1][2]
Late-summer flowers add a secondary seasonal moment after the foliage has filled its allotted space. Keep harvest access open from summer into fall by avoiding tightly packed companions at the base and by placing the plant within easy reach of a path. Its seasonal occupancy is longest where it can remain outdoors as a perennial; container placement keeps the layout flexible where winter protection is needed.
Lemon verbena is suited to USDA Zones 8 through 11 as a perennial. In colder climates, a container avoids leaving a large empty perennial space when the plant must be protected for winter. Choose a pot with enough visual and physical clearance for a plant that can form a broad, multi-stemmed canopy, and site it where moving it will not obstruct circulation.[1][2]
