What are the organization's current programs, how do they measure success, and who do the programs serve?

Ecological Horticultre

Everything we do at Jenkins is in partnership with nature. We garden with our ecosystem in mind, elevating native plants with high ecological value and providing critical habitat for pollinators and other wildlife. This unique approach to horticulture is becoming increasingly important as our world experiences dramatic changes in temperature, rainfall, and other climate-related events.

As a free public garden, Jenkins aims to inspire connection, conservation, and community action. We believe that through education, demonstration, and collaboration, we can transform visitors into champions for a healthier, greener planet.

Population(s) Served

At Jenkins, we encourage families to connect with one another and with nature during their visits. Through our Explorer Vest program, Explorer Garden, and youth programming, our youngest visitors are invited to express their curiosity, stretch their legs, and form a deep and lasting bond with nature.

With our free-to-borrow Explorer Vests, kids and their grownups can wander the gardens equipped with the investigative tools they need to actively engage with the habitat around them. Our Explorer Garden invites year-round play with creation stations that allow kids of all ages to build with natural materials as they build their imaginations. From nature-inspired crafts to kids mindfulness classes to our Jenkins Juniors series, we seek to foster a love of nature from a young age and provide children with the opportunity to develop their tactile and kinesthetic learning skills - tools which can help them connect more with nature, be that here at Jenkins or at home in the backyard.

Infants and toddlers

Jenkins Native Rhododendron Germplasm Repository is vital to the conservation and preservation of species, and selections of those species, that are native to the eastern United States. The primary goals of this Repository are to:

1. Acquire plants, cuttings, and/or seeds from known wild populations, grow them, plant them, and allow access to all who would like to view them.
2. Collect rare, unusual, and exceptional specimens.
3. Display and actively promote the ornamental value of these beautiful plants through programs, publications, and guided tours of the collection.

As a member of the Plant Collections Network, Jenkins actively collaborates with nurseries, other botanical institutions, botanists, collectors, and breeders to discover, evaluate, select, propagate, and exchange plants. This sharing ensures that there is duplication and that the plants will not be lost forever.

Population(s) Served

Our community is in desperate need of accessible natural land. The restoration of our Conservation Woodlands a site of 20 acres of forested land would double the size of the Arboretum, providing visitors with expanded access to nature and the opportunity to learn from the healthy, native habitat that is modeled. The restored woodlands will help to address the significant environmental issue of stormwater in our county, slowing down and soaking up water along a stream corridor notorious for flash floods. Restoration also positively impacts the health and resilience of our landscape and improves the Arboretums ability to serve as the lungs of our neighborhood.

Population(s) Served

Our 48 acres of woodland and gardens are maintained by a small, tireless team of three gardeners, weekly volunteers, and summer horticulture interns. Our internship program offers students the opportunity to gain practical experience alongside our talented team while providing much-needed help during a busy season. Interns are exposed to guiding principles of the organization during their tenure and learn to garden with the support and survival of pollinators and wildlife in mind.

Population(s) Served

We have worked hard to make Jenkins an approachable, accessible space for everyone who chooses to visit. With free admission and visitation hours every day of the year, some barriers to access are already removed. But theres still much more work to do! Through increased partnerships, expanded amenities, staff learning, and upgrades to our physical site, we will continue to make Jenkins increasingly approachable for all visitors.

Population(s) Served
People with disabilities

Our John J. Williaman Education Center acts as a hub for the community to learn about and explore topics related to ecological horticulture, climate resiliency, and environmental art. Throughout the year, Jenkins offers opportunities for people of all ages and backgrounds to interact with and learn about nature. Programs include free pop-up demonstrations in our garden shop, virtual lectures, and hands-on workshops on topics related to native seed propagation, planting for pollinators, cultivating soil health, participating in local sustainability initiatives, and more. From our Jenkins Juniors programs for toddlers to our global, virtual Third Thursday lectures for adults, we provide diverse settings and learning models to engage, educate, and inspire visitors to become better stewards of their own lands and resources.

Balance sheet

Fiscal Year: Jan 01 - Dec 31

SOURCE: IRS Form 990 info

The balance sheet gives a snapshot of the financial health of an organization at a particular point in time. An organization's total assets should generally exceed its total liabilities, or it cannot survive long, but the types of assets and liabilities must also be considered. For instance, an organization's current assets (cash, receivables, securities, etc.) should be sufficient to cover its current liabilities (payables, deferred revenue, current year loan, and note payments). Otherwise, the organization may face solvency problems. On the other hand, an organization whose cash and equivalents greatly exceed its current liabilities might not be putting its money to best use.
