Hydrophyllum tenuipes - Pacific waterleaf

Family: Hydrophyllaceae (Waterleaf family) [E-flora]

Origin Status: Native [E-flora]

"Hydrophyllum tenuipes is a PERENNIAL growing to 0.8 m (2ft 6in). The flowers are hermaphrodite (have both male and female organs)
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland). It prefers moist soil." [PFAF]

Introduction "Pacific Waterleaf is found in North America from southern British Columbia south to northern California (Douglas et al. 1999). It reaches its northern limits of distribution in British Columbia. In BC, it is restricted in occurrence to the Fraser Valley (in the Abbotsford area and Chilliwack areas) and southern Vancouver Island, where t occurs in clonal patches in rich moist soils in woods and along streams (Douglas et al. 1999). Populations in the Fraser Valley are significantly threatened by expanding urban development, directly through site loss and indirectly through habitat decline." [E-flora]

General: "Perennial herb from a short or elongate rhizome; stems spreading to ascending, solitary, usually reflexed-hairy, 20-80 cm tall." [IFBC-E-flora]
Leaves: "Mostly basal, 10-25 cm long, 6-15 cm wide, long-stalked, somewhat palmately divided into 5-7, hairy, toothed, pointed leaflets." [IFBC-E-flora]
Flowers: "Inflorescence of moderately compact, long-stalked clusters of funnel-shaped flowers; flower stalks 5-12 mm long; corollas green to greenish-white to blue or purple, 5-7 mm long, stalked, 5-lobed, the lobes 3-4 mm long; styles and stamens protruding beyond the corolla; calyces long-hairy on the margins, the lobes lanceolate." [IFBC-E-flora]
Fruits: "Capsules, round; seeds 1-3." [IFBC-E-flora]

Habitat / Range "Moist woodlands and streambanks in the lowland zone; rare on S Vancouver Island and the lower Fraser Valley; S to N CA." [IFBC-E-flora]

Edible Uses

Propagation
"Seed - best sown as soon as it is ripe in a cold frame. The seed usually germinates in early spring. Sow stored seed as early in the year as possible. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in spring or autumn[200]. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring." [PFAF]

Cultivation
"We have almost no information on this species and do not know if it will be hardy in Britain though judging by the plants native range it should succeed outdoors at least in the milder areas of this country. The following notes are based on the general needs of the genus. Requires a moist humus-rich soil in semi-shade[200]. Slugs are particularly fond of this plant and will soon destroy it if given a chance[K]." [PFAF]
