The Humboldt Botanical Garden is a 44.5 acres (18 ha) botanical garden located four miles south of Eureka, California, United States.[1][2] The Garden is near the South Bay portion of Humboldt Bay on the north side of the College of the Redwoods. Grading and site preparation began in August 2003. Featuring views of Humboldt Bay and the Pacific Ocean,[3][4] the garden opened in 2006, with more development completed by 2008.
HBG is listed by the California Native Plant Society as one of the 17 California gardens with notable California native plant collections.[7]
The Gardens were first organized in 1991.[1] Originally a farm, the site is a grassy escarpment with meadows and woodland, and a year-round stream.[8] The area's climate, which straddles Mediterranean and Pacific Marine[8] allows for a diverse group of plants.[1] Its Native Plant Garden has an emphasis on the Humboldt region, but includes plants from other geographic areas. Other gardens are: “All Happy Now” earth sculpture, meant to be walked in the way of meditation labyrinths;[8] Riparian Area; Greenhouse; the Temperate Woodland Garden; the Ornamental Terrace Garden;[9] Rose Garden; Heather Garden; Pollinator Garden;[10] Mediterranean Allee and Native Tree garden;[8] plus five miles of hiking trails.[11]
The Humboldt Botanical Garden is particularly interested in maintaining complete native conifer, Iris and Lilium occidental (western lily) collections. Its Mission Statement is: To cultivate a garden that provides an enjoyable discovery into the botanical world through education, participation and community service.[12]
A summer music series and an annual native plant sale are held in the gardens.[13] The gardens are available as a special events venue.[3]
Endangered Species Protection
In March 2023, HBG became the northernmost site for safeguarding the state-listed endangered species Vine Hill manzanita (Arctostaphylos densiflora) which is native to Sebastopol, Sonoma County, California.[14][15][16]
Another critically endangered species is the Wollemi pine (Wollemia nobilis), a native of Australia which has been planted at HBG.[8] It was known only from fossils until found near Sydney, Australia in 1994.[17]
Research
Active research in support of conservation, general research, and education is supported.[18] As of 2024, this has included research into Monterey Pines (Pinus radiata), habitats for native pollinators and their flower selection, removal of invasive species, and studying the effects of potential predation on foraging habits of bumblebees.[18]
Research has included collaborations with Wright State University, Academy of the Redwoods Environmental Club, and California Polytechnic University Humboldt.[18]
