The Root System of a Top Workplace: Longwood Gardens’ Growth Strategy

KENNETT SQUARE, PA – June 30, 2026 – Longwood Gardens, the sprawling horticultural institution born from an act of conservation in 1906, has received a modern accolade: a spot on Newsweek’s list of America's Greatest Midsize Workplaces for 2026. While the recognition is noteworthy, the underlying operational and human capital strategies that earned it are what demand closer inspection. In an era where companies grapple with employee retention and the very definition of a “good job,” how does a non-profit botanical garden build a workplace culture that stands out on a national stage?

The answer lies in a business model that treats its employees not as resources to be managed, but as assets to be cultivated. “We've worked hard to build a workplace defined by innovation, belonging, exceptional benefits, and real investment in our team's professional growth,” noted Shelley Dinehart, Longwood’s Chief Human Resources and Culture Officer, in the official announcement. This statement moves beyond typical corporate platitudes, pointing to a deliberate architecture of employee engagement. For leaders seeking actionable intelligence, the Longwood model offers a compelling case study in fusing mission with execution.

Deconstructing the Accolade

Before analyzing why Longwood Gardens won, it’s critical to understand the mechanics of the award itself. Skepticism is warranted in a market saturated with “best of” lists, many of which are little more than pay-to-play marketing schemes. However, the methodology employed by Newsweek and its research partner, Plant A Insights Group, adds significant weight to this particular honor.

The ranking for midsize companies, defined as those with 500 to 1,000 employees, is the result of a rigorous, multi-faceted analysis. It’s not based on applications or nomination fees—a strict “no-pay-to-play” policy is enforced. Instead, the foundation is built on extensive data, including over 2.6 million online employee reviews and a confidential nationwide survey that gathered millions of data points between 2022 and 2025. This quantitative approach is further enriched by a partnership with HR analytics firm Aniline, which assesses companies against more than 120 key performance indicators (KPIs). These metrics cover everything from leadership integrity and career development opportunities to compensation fairness and work-life balance. Being named to this list is not an accident; it is an evidence-based validation of an organization’s internal health.

The Architecture of a Human-Centered Workplace

Longwood’s success in this data-driven evaluation stems from a benefits and culture framework that appears both comprehensive and deeply aligned with its mission. The organization, which employs over 700 staff members and is supported by 600-plus volunteers, has engineered a value proposition that extends far beyond the intrinsic reward of working in a beautiful setting.

The benefits package is a cornerstone of this strategy. It includes a robust offering of medical, dental, and vision insurance, but also features modern provisions like expanded access to virtual primary care and physical therapy programs. Financially, the competitive retirement matching plan, tuition reimbursement, and paid parental and caregiver leave address key life-stage needs that are critical for talent retention. “The benefits for full-time staff are fantastic,” notes one employee in a public review forum, a sentiment echoed by many. These tangible investments promote a sense of security that allows employees to focus on their work and professional growth.

Beyond benefits, the institution has cultivated a strong focus on career development. The prestigious Longwood Gardens Fellows Program, a 13-month residency that trains global leaders in public horticulture, is the most visible example. However, the commitment permeates the organization, with tuition discounts for continuing education courses and a stated goal of supporting each staff member’s unique skills. This creates pathways for advancement in a field that isn’t always known for vertical mobility.

However, no workplace is a perfect paradise. The model is not without its operational challenges. A critical look at employee feedback reveals some common tensions. Several part-time or seasonal employees express a desire for more full-time opportunities, noting that the path to a permanent, benefited role can feel opaque. Others point out that while benefits are strong, compensation in some specialized horticultural roles hovers around the industry median rather than leading it. These are not damning critiques but are crucial data points for any leader looking to replicate this model; they highlight the persistent challenge of balancing a large, flexible workforce with the security of permanent roles, especially within the financial constraints of a non-profit.

An Economic Engine Fueled by Culture

The impact of Longwood’s workplace strategy extends far beyond its 1,100 acres. As a major employer in Chester County, the organization is a significant economic driver for the greater Philadelphia region. With over 1.6 million annual visitors, its primary function is as a cultural and tourism powerhouse. But its secondary function as a top-tier employer creates a powerful ripple effect.

This Newsweek recognition serves as a potent recruitment tool, enhancing Longwood’s ability to attract top talent not just from the local area but from across the country. In a competitive labor market, a validated reputation for a positive culture and strong benefits can be a decisive advantage. This helps anchor skilled professionals in the region, contributing to a more robust and diverse local economy.

The organization’s strategic growth, highlighted by the 2024 acquisition of the 505-acre Longwood at Granogue estate in nearby Delaware, signals a long-term vision. This expansion isn’t just about land conservation; it’s about scaling its mission, which will require integrating new staff and extending its lauded culture. This growth transforms Longwood from a single destination into a regional institution, amplifying its economic and cultural footprint.

Ultimately, Longwood Gardens demonstrates that a strong internal culture is not merely a “nice-to-have” but a strategic asset with quantifiable external returns. By investing deeply in its people, the organization has created a resilient ecosystem that fosters both human and horticultural growth, making it a model worthy of analysis. As organizations across all sectors continue to navigate the complexities of the modern workforce, Longwood Gardens provides a compelling case study on how investing in the root system—its people—is the most effective strategy for sustainable growth.
