Dictamnus (Gas Plant): Long-Lived, Aromatic Perennial for the Patient Gardener

A Plant Worth the Wait

Dictamnus (dick-TAM-nus) forms a sturdy, 2- to 3-foot clump of glossy, lemon-scented foliage topped in early summer with spikes of white or pink flowers. It’s slow to establish—often taking 2–3 years to hit its stride—but then lives for decades without division.

Critical Cultural Needs

• Site: Choose carefully; the plant resents disturbance.
• Soil: Average, well-drained garden soil.
• Safety: Wear gloves! Oils in stems and leaves can cause severe skin rashes in sensitive individuals.

Once settled, gas plant is essentially carefree—no fertilizing, no dividing, no serious pests.
