(P) 18″.  Wood Germander.  A tough, shrubby perennial native to dry, open, pine woods, scrub, heaths and sandy acidic soils throughout Western Europe.  Aromatic, notched and puckered, sage-like, wrinkled green leaves adorn dense clumps of stiff, branching, woody stems.  Masses of tiny, greenish yellow lipped blooms cover, short, loose spikes in mid to late summer.  Dry, lime free soil.  Sun. 3 & T2

Scientific Name (Genus/Species): Digitalis lanata (syn. Digitalis lamarckii)

Family: (Plantaginaceae)

(P) to 3′.  Native of Turkey.  Wonderful pubescent spikes of quietly dramatic, hairy, pale beige, helmet-shaped flowers with maroon netting inside, tinged with mustard.  A large, exaggerated, white lower lip adds to the drama.  Partial shade.  4 & T2

Scientific Name (Genus/Species): Romanzoffia californica

Family: (Boraginaceae)

(P) to 8″.  California Mistmaiden.  A native of California and southern Oregon, where it thrives on rocky ocean bluffs, moist forests and wet cliffs.  Tight, attractive clumps of high-gloss green succulent leaves are perfectly scalloped.  Early spring brings attractive, small, white, five-petalled flowers with pale yellow throats held in curving cymes above the foliage.  During the heat of summer, it dies back to a tuberous base and goes completely dormant.  Sun.  3 & 7 for 3 weeks, then T2

This herb yields a yellow dye often used for silks. We have enjoyed it in a pot and now love it in the garden. Sun. 3 & T2

Scientific Name (Genus/Species): Clematis texensis

Family: (Ranunculaceae)

Hardy vine to 9′.  Scarlet Leatherflower.  Southwest US.  Urn-shaped flowers consist of four, thick, leather-like, rose-red to scarlet coloured tepals that recurve at the tip to reveal a paler interior.  Flowers are borne only on new growth and are held atop purple pedicels in axillary clusters of one to seven. The delicate foliage is a glaucous green and the ovate to rounded leaves with wavy margins enhance the charm of the flowers.  A mass of feathery balls of plumed achenes follows the floral display. At Stonecrop ours grows in a crevice on the Rock Ledge.  This is a very hardy and relatively drought tolerant Clematis.  A long bloomer from mid-summer through fall.  3 & 7 for 8 weeks, then T2

Scientific Name (Genus/Species): Narcissus viridiflorus

Family: (Amaryllidaceae)

Tender bulb to 12″. Southwest Spain, Morocco. Grows in damp fields, blooming in autumn. Like the name suggests, this Narcissus has green flowers. Umbels of three to five slender-petalled, matte green, sweetly scented flowers are very petite and delicate. Extremely choice. Sun. 3 & T1

Scientific Name (Genus/Species): Amsonia ciliata

Family: (Apocynaceae)

(P) to 20″. Narrow-Leaved Bluestar. This native of open sandy woodland and prairies from North Carolina to Missouri resembles a petite, more refined version of the Arkansas Bluestar (Amsonia hubrichtii) with five-petalled, starry, periwinkle-blue flowers in early summer. The narrow, almost needle-like foliage turns a brilliant golden yellow in the fall. Dry, well-drained soil. Sun. 3 & 7 for 12 weeks, then T2
