Phlomis

Phlomis
A small genus of perennials and shrubs that are part of the larger Labiatae family.
They prefer full sun on light, very well drained soil that is preferrably somewhat dry during summer.
Drought tolerant and deer resistent. Propagation is from either softwood cuttings taken during summer or seed sown in autumn. Clumps can be divided during autumn or early spring.

Phlomis cashmeriana ( Kashmir Sage )
A woody based, shrubby perennial, reaching up to 4 x 2 ( rarely over 3 ) feet, native from Kashmir into the western Himalayas. It makes a great architectural focal point for hot sunny urban gardens, parking lot islands and house foundations. Looks great mixed with ornamental grasses.
The attractive hairy foliage is silvery at first, turning to gray-green.
The showy, lilac-purple flowers are borne on whorled clusters during summer.
The stems are white and felted.
Hardy zones 5 to 9 in sun or shade on well drained soil. Very heat, drought and clay tolerant. Rarely bothered by pests or disease. Cut back after blooming but make sure to leave the very attractive foliage. Cut back hard during early spring before growth begins.
Propagation is from seed or cuttings taken during early summer.

Phlomis chrysophylla
An erect, small, shrubby perennial, reaching a maximum size of 6 x 4 feet, that is native to Lebanaon.
The broad-oval leaves, up to 2.5 inches in length, are gold-felted at first, turning to yellowish-gray.
The bright yellow flowers are borne on whorls originating from the leaf axils during summer.
Hardy zones 7 to 10

Phlomis fruticosa ( Jerusalem Sage )
An upright to spreading, evergreen shrubby perennial, reaching a maximum size of 8 x 8 ( rarely over 5 ) feet, that is native to dry hillsides in the Mediterranean region. It tends to look a bit wild, thus not really fitting into a formal garden despite being an excellent foliage plant.
The wrinkled, oval leaves, up to 8 x 2 inches, are gray-green.
The aromatic foliage is furry.
The bright yellow flowers are borne in whorls, up to 2 inches across, around the shoots from early to mid summer.
The flowers are whorled around the shoot tips.
The stems are square.
Hardy zones 4 to 9 ( shrub in zones 8 & 9, perennial in zone 6 & 7, requires protected site in 4 & 5 ) in full sun on dry, well drained soil, preferring a site protected from excessive wind. Tolerant of salt winds and sand, making it an excellent landscape plant for the seashore. Excessive moisture during winter and spring can rot and kill a plant. Deadheading will extend the flowering season.
During autumn, cut plants back by half to encourage compact and dense habit, during early spring remove freeze damaged wood.
