Description (Jepson, PlantID.net)

• Eudicotyledon
  • Eudicots are a major lineage of flowering plants; see family for general characteristics
• Honeysuckle Family (Caprifoliaceae)
• Deciduous to evergreen liana (a woody, rope-like vine)
• Leaves and stems covered with hairs and glands
• Leaves
  • Opposite, oblong to ovate
  • Upper leaf pairs fused around the stem
  • Become purple-tinged with summer-fall drought
• Flowers
  • Inflorescence (flower arrangement) consists of paired clusters of white to pink flowers that form just beyond the fused terminal leaves
  • Tubular and 2-lipped
    • Lips about as long as the tube, curling back as the flower opens
    • Upper lip shallowly lobed with 4 fused petals
    • Lower lip with 1 petal
  • Both stamens (male flower parts) and pistil (female flower part) extend beyond the petal
  • Ovary inferior (below the attachment of other flower parts)
• Fruit is a berry (a usually multi-seeded fruit with a fleshy ovary wall), initially green, turning bright red and translucent at maturity
• Height to 20 ft.

Distribution

• Native to California
  • Grows in mixed evergreen forests and foothill woodlands, on slopes and along stream banks
  • See Calflora for statewide observations of this plant
• Outside California, extends into southern Oregon
• Grows at elevations to 3,600 ft.

Uses (San Mateo County Parks prohibits removal of any natural material)

• Flowers attract hummingbirds and insects, especially bumblebees
• Fruit eaten by birds
• Native people used the hollow stems for pipe stems and used wood ashes to make a paste for tattooing
• CAUTION – some sources indicate the fruit is edible but bitter, while others say the fruit is poisonous. Best to leave them for the birds!

Name Derivation

• Lonicera (lon-IS-er-a) – named in 1753 by Carl Linnaeus in honor of Johann Lonitzer, a German herbalist and physician (1499-1569) and/or his son, Adam Lonitzer, a German herbalist, physician, and botanist (1528-1586)
• hispidula (his-PID-yoo-la) – from the Latin for “little bristly hairs”
• Honeysuckle – refers to the sweet nectar

Notes

• Unlike the flowers of horticultural species, pink honeysuckle flowers are not fragrant
• This species tends to be evergreen in a mild climate (Ladybird 2018)
• Have you noticed California buckeyes with distorted trunks along the lower Sylvan trail? Most likely these were made by rope-like honeysuckle vines, wrapping around the trunks and persisting as the trees grew
• Host to the fungus-like microorganism Phytophthora ramorum, which causes Sudden Oak Death (SOD)
  • At Edgewood, the 2 species known to be susceptible to SOD are coast live oak (Quercus agrifolia var. agrifolia) and Pacific madrone saplings (Arbutus menziesii)
  • For a complete list of known hosts and host associates see USDA Risk Analysis for Phytophthora ramorum, pp.6-9
