Choosing native plants for your landscape should be fun and creative, not daunting or complicated! When you consider plants in simple groupings, or guilds, it becomes a lot easier to design a landscape with appealing texture, color, and wildlife value throughout the seasons. Native plant guilds draw on inspiration from natural plant communities in habitats like coastal plains, forests, wetlands, or mountain tops.

Rock garden and alpine plants are wonderful additions to any garden, bursting with fine details particularly suited to up-close viewing.

State Horticulturalist Gary Fish will emphasize preventative measures and help students determine the methods to mitigate further plant-pest problems.

When selecting landscape plants, flowers tend to get most of our attention. But when flowers start to fade, what’s better than being able to shift our attention to a fabulous foliage display? There are so many options, from a variety of colors and textures to leaf shape and qualities—tiny succulent-like leaves to enormous papery-thin specimens. In this field-study class, Director of Horticulture, Andy Brand, takes students around the Gardens to see and learn all about the features of foliage and their ecological adaptations. Come ready to take pictures because we’re certain you’re about to make your next horticultural discovery, perfect for the garden or woodland.

In this field-study class, Jeff O'Donal, nurseryman and conifer grower, will explore the extensive world of conifers, including native and non-native species, specimen plants and those great for naturalizing into our native landscapes. Diverse, conifers grow in all sorts of shapes and sizes, and the needle species offer so many options: variations of gold and blue, soft or coarse textures, varieties of needle lengths, deciduous or evergreen, fragrant or neutral—there’s something for every style and landscape, from gardens to containers.

Our gardens and gardening practices are intrinsically tied to nature. This class will guide students through the best design and management strategies that work in unison with nature, encouraging and embracing biodiversity and sustaining healthy, low-maintenance gardens. Anna Fialkoff, Program Manager at Wild Seed Project, offers an overview of plant selection and processes for achieving beautiful gardens requiring minimal manual labor.

What exactly is a specimen tree? Good question! Specimen trees are trees that fulfill specific garden design goals, such as providing focal features, provoking emotional responses, or contributing to specific themes, just to name a few. The trees can be small, large, narrow, or broad, cascading or twisted in habit, or provide foliar accents in an otherwise monochromatic setting. In this class, landscape designer and horticulturist Irene Barber will take students on a landscape-design tour around the Gardens to learn about specimen trees to consider adding to a new or existing garden back home.

Join Andy Brand, the Gardens’ Director of Horticulture, on a walk to identify native edible plants living in their desired natural habitats, then learn how to incorporate these edibles into your home garden. Rather than foraging, this class focuses on the opportunity to grow these native edibles sustainably at home, leaving the foraging to the wildlife who need these plants for survival.

Oaks sustain a complex and fascinating web of wildlife. Come learn what happens in their branches, month by month, a tangible cycle of life, death, and renewal. From woodpeckers harvesting hundreds of acorns to the jewel caterpillars grazing greenery, Tallamy describes and celebrates these backyard wonders. Learn practical advice about planting and caring for oaks and the best oak species for your area. Leave inspired to treasure, nurture, and protect these remarkable trees.

Whether designing one garden or several, the first step is to learn the foundation and classical inspirations of garden design. Understanding design principles and becoming aware of how garden design has evolved through the centuries and is represented through different cultures helps new designers establish a basis and broadens perspectives. In this online class, Irene Barber, landscape designer and the Gardens’ Adult Education Program Manager, will introduce students to garden themes from different cultures and civilizations, all of which relate to the principles and elements of design relevant to today.

Geography and cultural history are pertinent factors when making garden design decisions, particularly in New England’s unique and diverse landscapes, from river valleys to rolling fields to narrow, rocky corridors. In this online class, students will learn how to establish a sense of place and belonging, wherever their prospective garden is to be located. No matter what cultural elements and influences you want to incorporate, this class will help you get creative while staying true to a sense of place.

Creating a base plan for a plan-view design of your garden may not be the most exciting part of the process, but it is an all-important one! This in-person class will present and allow practice in how and what to measure for a new garden or multiple gardens before translating the information into a scaled drawing. During this stage, students will begin developing a design key and practice drafting skills. A scaled base-plan will be necessary to properly pursue further design stages and enable the designer to practice sketching with trace paper and explore ideas. Upon registration, students will receive a list of supplies needed to pursue their own design project and to have ready for this class.

Whether designing a secret garden or an extensive wildflower garden, it’s critical to evaluate, document, and sketch out a setting's details—built features, water movement, sun exposure throughout growing months, soil types and so on. This online session will help students develop longhand documentation and, more importantly, sketch the assessed information, resulting in a visual diagram that provides a clearer understanding of any variables to consider. The more informed you are as a designer, the better a designer you’ll be! We strongly recommend students to have a scaled base-plan in-hand before moving forward with this stage. Upon registration, students will receive a supplies list that will be useful for designing a new garden.

When we design a garden, we do so much more than simply create a space to show off favorite flowers—we create one that reflects personality and a sense of place, incorporating circulation, function, and design principles. Join us at the Gardens as we explore the conceptual process that awakens creativity and trains the brain to draw freehand, while learning how to use graphic tools. We’ll practice with onsite spaces, and have time for students to apply newfound skills to their own personal projects. Upon registration, students will receive a list of supplies needed to pursue their own design project and to use during this class.

Once we have the conceptual ideas narrowed down to one or two general schematics of our garden spaces, we can start shaping them with program and structure. Structure and movement consist of more than a row of shrubs, a fence, a path or a wall at your property line – this is how you shape a space, create a sense of enclosure, and lead the eye to landscape destinations. This online lecture and demonstration will identify features and design principles captured initially on trace layers, which will ensure both pragmatic and inspirational function in our gardens. After this class, students will feel empowered to practice on the personal project that will help them prepare for the next class, Garden Design: Details in the Layers. Upon registration, students will receive a list of supplies recommended to pursue their own design project.

Practice your skills and learn more about the plants to prune during certain times of the year with Gardens Horticulturists Irene Barber and Brent McHale. In this hands-on workshop, we'll discuss the variety of pruning methods and techniques needed depending on plant setting, plant health, and any desired goals. Students will have the opportunity to use different tools during the workshop, learning when and how to use them properly as well as how to maintain them for optimal long-term performance.
