From botanical gardens and arboreta to parks, universities, zoos, and public gardens, professional plant identification signs help visitors learn about the landscape while creating a polished, organized appearance. Lark Signs manufactures a complete line of custom plant ID signs, plant markers, tree identification signs, and botanical garden labels designed for years of outdoor use. Whether you're identifying individual specimens, labeling an entire collection, or creating educational displays, our weatherproof plant markers are built to withstand rain, sun, and daily exposure to the elements. Choose from engraved aluminum plant markers, vibrant full-color plant identification signs, low-profile NameStake® markers, or innovative changeable plant markers that make updates quick and easy.

Plant Markers for Every Landscape

No two gardens are alike, which is why we offer a variety of outdoor plant labels and botanical garden signs to meet your needs. Our full-color plant markers showcase stunning photography, illustrations, logos, and educational content, making them ideal for botanical gardens, arboreta, nature centers, museums, and pollinator gardens where visitor engagement is a priority.

For a clean, understated appearance, our NameStake® plant markers provide durable identification for trees, shrubs, perennials, and native plants. Their low-profile design is mow-friendly, kid-friendly, and trip-friendly, making them a popular choice for public gardens, parks, schools, and high-traffic landscapes.

For collections that change over time, our Mini Flip and Easy Swap changeable plant markers provide the flexibility to update information without replacing the entire sign. Easily change plant names, botanical classifications, accession numbers, donor recognition, seasonal displays, or educational content in just minutes. No special tools are required—simply unlock the marker, replace the printed insert, and secure it back into place. It's an ideal solution for botanical gardens, research facilities, universities, and organizations that regularly update plant collections.
