Description
The Diptam, botanically Dictamnus albus, is a long‑lived aromatic herb of the Rutaceae family that can remain in the same spot for decades when given a suitable location. In early summer, usually from late May to early July, it produces pink to white flower spikes that release fine aromatic oils; on hot, calm days these vapors can even briefly ignite, giving rise to the name Burning Bush. The plant’s sap is phototoxic and can cause painful redness and blisters when it contacts skin in sunlight, so keep it away from children and pets and wear gloves when handling. In the wild the Diptam is protected and wild harvesting is prohibited; for gardens, use only plants or seeds from reputable garden suppliers. Roots and foliage have been used traditionally in folk medicine, but any medicinal use should be undertaken by qualified professionals.
Care instructions
Diptam prefers a sunny, warm spot with well‑drained, slightly calcareous soil and tolerates drought once established. Sow seeds in the fall (September or October, weeks 37 to 40) directly in the ground; seeds need a cold period to germinate and may take one to two years to sprout, so patience is required. Avoid waterlogged or heavy, compacted soils without drainage, as rot is the plant’s biggest enemy. After establishment, minimal care is needed: in spring, simply cut back any dead stems from the previous year and let the plant grow undisturbed, as it does not transplant well. When pruning, wear gloves and long sleeves to protect against skin irritation from the sap.
