Saxifragaceae: Saxifrage  Family

Brook Foam – Boykinia occidentalis

Blooms:

Apr–July

Plant Height:

15–60 cm

Flower Size:

Small

Origin:

Native

Habitat:

Shady wet streambanks

Notes:

Aptly named, this is found by streams or on the faces of waterfalls. It has distinctive indented, round to ovate leaves. The diminutive 5-petaled flowers are white and bell-like, in small open clusters. Peduncles are slender, erect, long and branching with minute, brown, gland-tipped hairs.

Alum Root / Small-flowered Alum Root – Heuchera micrantha

Blooms:

Apr–July

Plant Height:

10–100 cm

Flower Size:

Very small

Origin:

Native

Habitat:

Moist rocky banks

Notes:

This is easily recognized by its distinctive, deeply 5–7-lobed leaves with prominent reddish dark veins. It has a tall slender stem with lateral peduncles bearing many tiny white and pinkish flowers with a tapering, slightly hairy hypanthium.

Seaside Alum Root – Heuchera pilosissima

Blooms:

May–June

Plant Height:

15–55 cm

Flower Size:

Very small

Origin:

Native

Habitat:

Rocky shady places near coast

Notes:

A much smaller plant than Small-flowered Alum Root (Heuchera micrantha) and with a generally more compact appearance. The flowers are noticeably different; these are in denser clusters, have less exserted stamens, and are rounder and densely hairy. Calyx lobes are pink to red.

Woodland Star – Lithophragma affine

Blooms:

Mar–Apr

Plant Height:

10–60 cm

Flower Size:

Small

Origin:

Native

Habitat:

Open grassy slopes

Notes:

This and Hill Star (Lithophragma heterophyllum) are two equally beautiful early spring bloomers with similar pure white flowers and growth habits. The slender, many-flowered stems may be either green or reddish. The two species are readily distinguished by their hypanthium. Woodland Star has an obconic, tapered hypanthium. Hill Star’s is truncate, with a squared-off base.

Hill Star – Lithophragma heterophyllum

Blooms:

Feb–July

Plant Height:

15–50 cm

Flower Size:

Small

Origin:

Shaded woodland slopes

California Saxifrage – Micranthes californica

Feb–June

Plant Height:

15–35 cm

Flower Size:

Small

Shaded woodland slopes

This is another common early spring bloomer, sometimes found in profusion. The leaves are in a basal rosette, hairy and slightly toothed. There is a single stem, long and branching, green or red, bearing loose clusters of small white flowers, 5-petaled and with 10 bright orange-red anthers.
