Holon Gardens / Holon Foundation
Effective Date: April 6, 2026
Holon Gardens is committed to the conservation of native plants and the protection of Texas's unique ecological heritage. This policy governs all native plant trade, conservation classification, and herbicide safety within the Holon Gardens marketplace. It aligns with TPWD Code Chapter 88, the federal Endangered Species Act, the Convention on International Trade in Endangered Species (CITES), and Texas Department of Agriculture (TDA) herbicide regulations.
This Native Plant Conservation & Regulatory Compliance Policy establishes guidelines for:
This policy applies to all sellers, buyers, and facilitators using the Holon Gardens marketplace for native plant commerce. Violations of this policy may result in account suspension, marketplace removal, legal penalties, and reporting to regulatory authorities including Texas Parks and Wildlife Department (TPWD) and the U.S. Fish and Wildlife Service (USFWS).
The Holon Gardens marketplace uses a tiered conservation classification system to balance ecological protection with stewardship incentives. Plants are assigned to one of six categories:
Native species with stable populations and no regulatory restrictions. These plants are free to trade without any restrictions or documentation. No marketplace flags apply.
Species designated by United Plant Savers as at-risk due to over-harvesting or habitat loss. Trading is permitted only with cultivated-origin attestation from the seller. These species require a checkbox confirmation in the marketplace form confirming that plants were cultivated (not wild-collected). Annual review of conservation status is recommended.
Native species showing early signs of population stress or limited distribution range. Trading requires both cultivated-origin attestation and supplemental documentation proving plants were grown specifically for commercial harvest. Documentation must include: seed source, planting date, cultivation location, and cultivation method (propagation vs. direct collection). Sellers must maintain records for audit purposes.
Texas Parks and Wildlife's designation for species requiring proactive conservation action. SGCN species require full documentation including species identification, cultivation source, and location history. The marketplace will flag these species prominently and may require seller verification. TPWD monitoring is recommended for these listings.
Species critical to ecosystem function and pollinator relationships. These include species like milkweed (critical for monarch butterfly survival). Trading is encouraged and promoted within the marketplace but requires basic documentation of origin. These species may receive marketplace promotion and incentives to increase availability.
Texas state-symbolic species and culturally significant natives. Trading is permitted with source documentation confirming the plant's origin and cultivation history. Examples include the Texas Bluebonnet and State Grass. These species receive special marketplace designation and educational context.
The following species are absolutely prohibited from Holon Gardens marketplace listing without proper TPWD permits and regulatory authorization. These species are protected under state and/or federal law. Any listing of these species without appropriate permits will result in immediate removal and account suspension, plus reporting to TPWD and USFWS.
Sellers and buyers must verify that species are not on this exclusion list before completing any marketplace transaction. The marketplace includes automated screening to prevent listings, but ultimate responsibility rests with participants. Violations result in immediate account termination and regulatory reporting.
The Texas Parks and Wildlife Department (TPWD) administers Chapter 88 regulations governing the collection and trade of protected plants on private land. For species not on the federal exclusion list but regulated by TPWD, three mandatory conditions must be satisfied before commercial trade is permitted:
Collectors must obtain written permission from the landowner before harvesting any protected plants from private land. This documentation must be maintained and available for audit.
Commercial harvesters must obtain a Texas Parks and Wildlife Commercial Plant Permit. This permit authorizes the collection of specified protected plant species under defined conditions. Permit holders are subject to TPWD monitoring and reporting requirements.
Each harvested plant must be tagged with an official TPWD identifier tag at the point of harvest. Tags cost $1.00 per tag and are issued by TPWD. However, plants grown in cultivation for the express purpose of commercial sale are exempt from tagging fees (see Section 5 on Cultivated-Origin Attestation).

For plants in the At-Risk (Tier 2), To-Watch (Tier 3), and SGCN (Tier 4) conservation categories, sellers must certify that plants were "planted and cultivated for the express purpose of being harvested for commercial purposes." This distinction is critical for regulatory compliance.
All marketplace listings for conservation-flagged species (Tier 2-4) require the seller to check a mandatory checkbox confirming: "I certify that these plants were planted and cultivated for the express purpose of being harvested for commercial sale, and were not wild-collected." This certification is legally binding and subject to audit.
The cultivated-origin attestation qualifies sellers for the TPWD tagging fee waiver, reducing the cost of compliance and incentivizing responsible cultivation practices.
Violations of native plant conservation laws carry severe penalties at federal and state levels. Sellers, buyers, and marketplace facilitators must understand the legal consequences of non-compliance.
Any interstate transportation of illegally collected endangered plants violates the federal Lacey Act:
Any international trade in protected plant species listed on Convention on International Trade in Endangered Species schedules results in:
Beyond legal penalties, wild-collection of endangered native plants causes irreversible ecological damage:
Many protected species have critically small populations. A single harvest event can reduce the population by 5-10%, making recovery increasingly unlikely. Species like Navasota Ladies'-tresses exist in fewer than 20 known populations globally; each collection event is devastating.
Wild-collection typically targets the most accessible, healthiest plants. This removes the most genetically fit individuals from the population, reducing genetic diversity and the species' capacity to adapt to environmental change. Inbreeding depression becomes inevitable in small populations.
Native plants are keystone species supporting entire ecosystems. When endangered plants are removed:
For example, milkweed depletion directly correlates with monarch butterfly population collapse. Loss of native oaks eliminates acorn-dependent wildlife. These ecological consequences are permanent and affect biodiversity far beyond the single species.
The Holon Gardens marketplace serves stewards, gardeners, and professionals who may use herbicides in landscape management. Herbicide misuse poses risks to native plants, pollinators, and non-target species. This section provides safety guidance aligned with Texas Department of Agriculture (TDA) regulations and Harris County special restrictions.
The following herbicides require special safety protocols when used near native plant gardens or in ecologically sensitive areas:
These safety protocols apply to all marketplace participants using regulated herbicides:
Small-scale residential use has limited exemptions under TDA regulations, but these do not eliminate the need for safety protocols:
Harris County (Houston area, home to Holon Foundation) has additional restrictions beyond state requirements due to environmental concerns and proximity to sensitive coastal ecosystems:
These methods minimize off-target drift and collateral damage to native plants:
Texas Department of Agriculture (TDA) maintains updated pesticide regulations and county-specific seasonal restrictions:
The following species are candidates for inclusion in Holon Gardens marketplace conservation trading programs. These species have positive conservation rationales and could be added to the marketplace under appropriate permit-gated pathways, with proper seller verification and documentation requirements.
Conservation Rationale: Endemic to rare Neches River wetland systems in Southeast Texas. Critically endangered due to habitat loss from development and water management changes. Currently federally listed as endangered.
Marketplace Potential: Could be cultivated by native plant nurseries under TPWD permit. Marketplace listing would require proof of cultivated origin and TPWD permitting. Selling cultivated specimens would provide economic incentive for propagation and long-term preservation.
Conservation Rationale: Rare endemic of South Texas, with only a few known wild populations. Loss of shrub-scrub habitat threatens this species. Cultivation and distribution would create genetic repository.
Marketplace Potential: Native plant specialists could propagate this species. Marketplace listing would increase availability to stewards and reduce pressure on wild populations. SGCN designation makes this a conservation priority.
Conservation Rationale: One of North America's rarest orchids, with fewer than 20 populations remaining globally. Federal endangered status. Propagation and distribution are critical to species survival.
Marketplace Potential: Specialized native plant growers can propagate this species from seed or tissue culture. Marketplace listing would create a legal alternative to wild-collection and establish a cultivated gene pool for future restoration efforts.
Conservation Rationale: Rare sand dune endemic in South Texas, threatened by coastal development and dune degradation. Federally listed as threatened. Maintaining cultivated populations protects against extinction.
Marketplace Potential: Can be propagated from seed. Marketplace presence would support nurseries maintaining cultivated populations and provide stewards with legal, sustainable sourcing options. Specialized growing knowledge required but feasible.
Implementation Note: Each of these species would require:
