BUPLEURUM FRUTICOSUM
Impervious to drought and scorching temperatures, this stalwart, Mediterranean shrub makes a first-rate choice for well-drained soil, where it will form a large, evergreen dome adorned with a mass of chartreuse umbels in late summer. A light prune in early spring keeps it compact, but it also responds well to a hard prune if it has become rangy or was damaged by cold weather. Propagate by seed or semi-ripe cuttings taken in midsummer. We also grow B. falcatum, a short-lived perennial, which is allowed to self-seed in our Gravel Garden.
