Scientific Name (Genus/Species): Symphoricarpos albus

Family: (Caprifoliaceae)

Deciduous shrub to 6′.  Snowberry.  This North America native is thicket-forming, with wiry branches and oblong-elliptic to rounded, opposite, green leaves.  Tiny, bell-shaped, pink flowers bloom in clusters in the leaf axils.  The flowers are followed by bunches of globose berries that begin pale green in colour but ripen to snow-white by late summer to early autumn.  The attractive fruits last into winter, creating a dramatic effect of white berries perched on leafless branches.  Grows naturally on dry, rocky, woodland slopes, banks, and barrens.  Sun.  3 & 6A & Δ

A stunning beauty for the late summer garden.  Sun/partial shade.  3 & 7 for 8 weeks, then 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
