Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11
Botanical Name: Cynara cardunculus sih-NAR-ah kar-DUN-kew-lus Common Name: Cardoon Genus: Cynara
Cardoon is an architectural splendor with bold texture, thanks to its large, prickly, almost dagger-shaped gray-green arching leaves and a statuesque, vase-shaped frame. It is topped with round, purple, thistlelike flowers in midsummer. Cardoon can reach up to 5 feet tall and 4 feet wide.
 Noteworthy characteristics: A close cousin of the artichoke, this native to the well-drained, sunny slopes of the southwest Mediterranean can overwinter in Zone 7. Produces magnificent flowerheads that can be cut and dried for arrangements. Edible leaf stalks and midribs are tasty when blanched. Unopened flowerheads can be eaten like artichokes.
 Care: Plant in a sheltered location in full sun with fertile, well-drained soil.
 Propagation: From seed, if planted early enough, it will flower the first year. Divide in spring or insert root cuttings in winter.
 Problems: Gray mold, root rot, slugs, and aphids can cause damage.

'Indigo Spires' sage is a vigorous hybrid prized for its 12- to 15-inch-long, twisting spikes of dark violet flowers. It is a non-stop bloomer from early summer through fall. Blooming can be further encouraged by pinching stem tips early in the growing season and deadheading the spikes once they fade. 'Indigo Spires' quickly grows to 4 feet high, and can be grown as an annual where not hardy.

Cooks and gardeners alike are indebted to this evergreen perennial for the unique, pungent flavor and aroma that its gray-green leaves produce. This cultivar has leaves suffused with steely-gray purple. It forms a 1.5-foot-tall and wide bush with woody stems that may be trimmed back to newly emerging growth or strong stems in spring. In early to mid-summer, it sends up lavender-purple flower spikes; it has both ornamental and culinary qualities in an herb garden. It tolerates alkaline soils, but cannot survive wet winter conditions.
