Andy Brand |After The Flowers Have Faded: Plants with Fabulous Foliage | Sunday, January 16, 2021

Flowers always get most of our attention when we are selecting plants to add to our landscapes. But most plants only flower for a short period of time out of the year. It is the foliage that we will be looking at the entire growing season. Join Andy as he explores a broad diversity of awesome plants whose leaves will shine in the garden.

For 27 years Andy Brand was employed at Broken Arrow Nursery in Hamden, CT, where he was the nursery manager. In March 2018, Andy joined the staff at the Coastal Maine Botanical Garden as Curator of Living Collections. His responsibilities include plant selection, introducing new plants to the Garden’s collection and maintaining plant records and labels. In November 2021, Andy was named Director of Horticulture there.

Andy is past President of the Connecticut Nursery and Landscape Association and is an avid naturalist. He is a cofounder and past President of the Connecticut Butterfly Association. He has put his interest in native plants to use as a volunteer for the New England Plant Conservation Program where he has helped monitor historical sites of endangered native plants. He has spoken to groups throughout the northeast on a range of topics including native plants, new and unusual ornamentals, butterfly gardening, butterflies and their life histories, and increasing biodiversity in landscapes. Andy, along with his wife Michelle, lives in Bristol, Maine. Andy also has a Facebook page, Seeing Nature: Observations from New England, dedicated to native flora and fauna.

William Cullina | What do You Mean I’m Not a Perennial!?! Native Shrubs and Small Trees for Perennial Companionship | October 17, 2021

Most folks are familiar with the concept of the mixed border – perennials, annuals, shrubs and evergreens blended together in a seamless composition year-round. It sounds good in theory but transplanting this concept into a real garden is more difficult than it seems. Not all woody plants mix well with perennials and annuals for several reasons, including differing soil and fertilization needs, incompatible growth habits, aggressive root systems, or fear of crowds. This said, there are a number of native shrubs and small trees that mix wonderfully with herbaceous perennials and annuals. Many can even be cut back every year or two just like their non-woody neighbors to control their size and promote flowering and vigorous growth. In this talk, Bill Cullina will profile his favorite fifty “natural mixers,” focusing native woody plants that bring, form, texture, color and wildlife to the perennial garden.

Dan Hinkley | Windcliff: People, Places, Plants | June 13, 2021

Windcliff, a 6.5 acre garden on a high bluff overlooking Puget Sound, is the second garden of horticulturist Dan Hinkley and his partner, architect Robert L. Jones, the first being the still-legendary Heronswood. With a due south facing aspect, and thirsty soils, Hinkley began to visualize the garden in 2000 while Jones set about designing their house. Both horticulture and architecture were meant to be inseparable.

Propagating Your Own Plants from Seeds | January 8, 2022

Growing your own plants from seeds can be one of the most rewarding as well as economical ways to add annuals and perennials to your garden. And what better time to do this than during the winter days that you are otherwise only daydreaming about when you will next be able to work in your garden again?

I recall when, as a beginning gardener, I plunged in and started a variety of plants from seeds, and those became the backbone of my perennial herb garden, still thriving today. I still look at those herbs, and other perennials that I grew from seeds started indoors, with more pride than many of the other plants I purchased. In January and February each year I direct sow poppy and other annual plant seeds outdoors (amongst the most admired plants in my garden), and in early spring some annual and biennial herbs. And with advice and tips from our fellow gardeners, we can all start our gardening new year by giving this a try.

That is why I am pleased to announce that one of our own HAH members will help us do just that at our next Roundtable.

Dr. Jane Corrarino, who gardens in Setauket, NY, enjoyed a 40-year career in public health. After retiring, and with the pandemic altering her life, she decided to expand her gardening knowledge and skill set, which she has loved since childhood. Jane earned a Master Gardener certificate from Cornell, and is now a happy volunteer for them. Her volunteer action project for the Master Gardener program was to recreate a historically accurate colonial kitchen garden at the Ketcham Inn, a restored 1695 Inn/Museum in Center Moriches and on the National Register of Historic Places (Thomas Jefferson and James Madison stayed there in 1791). There are 3 gardens on site, including the kitchen garden, which contains herbs, vegetables and flowers all germinated from seed. In addition, they are restoring a boxwood garden and community garden on the site. And since Jane has said she welcomes anyone interested to visit the inn’s gardens, I hope this will be one of our in-person Garden Tour destinations later this year.

Plants to Make Your Late Summer Garden Dazzle |October 2, 2021

HAH member Pamela Harwood will present an extensive selection of August/September standouts, and we are very fortunate to welcome back Brian Smith, Vice President of the Long Island Native Plant Initiative, who will walk us through his own list of late-season-blooming plants that are native to Long Island. Both presenters will “screen share” photographs of these wonderful selections.

October is a good time to re-assess your garden while you can see all your plants in place (unlike spring when so much has not yet come up and you forget what is where!), garden centers are more likely to have these late-season plants in stock, and some may be on sale. The cooler temperatures will also enable plants to establish themselves before the hard winter frost and spring.

Attracting Butterflies, Bees & Other Pollinators to Your Garden | April 3, 2021

As this was our last scheduled Roundtable before we’ll all be purchasing new plants and back outside spending time in our gardens, we thought the timing was perfect to discuss how important pollinators are to the success of our gardens and to the environment. And since not all plants, no matter how beautiful, attract pollinators, we want to focus on sharing information about the plants — be they trees, shrubs, perennials, and annuals — that do the job. Many of these selections of course will be plants that are native to Eastern Long Island. But others are native to other areas of North America and even other parts of the world. But they all share characteristics that attract and nurture pollinators in various ways and at various stages of their life cycles.

Sarah Alford will speak about attracting butterflies to your garden. Brian Smith, Vice President of the Long Island Native Plant Initiative, will focus on the native plants that host and nurture bees and other pollinators in our gardens. We will go beyond plant varieties and also suggest how various selections may be best placed in your garden for maximum enjoyment, and other garden elements that are important for our pollinator friends.

Q&A follows. Moderated by Pamela Harwood

Explore the Versatility of Herbs with Joan DiMonda | April 17, 2021

With clear blue skies and warmer temperatures Spring is upon us. It brings with it a chorus of returning birds, the hum of buzzing bees and the rush of new emerging green shoots. Springtime reminds me of rebirth, renewal and reawakening.

In my herb garden all seems quiet, the noise level is low but the movement and activity underfoot is rapid and robust. CDC Guidelines have had us washing our hands many times this past year. Adding a fragrant herbal scrub to our routine will enhance this process…both a sugar scrub and a salt scrub will be discussed and prepared.

From sachets and potpourri to medicinal or culinary, herbs influence many areas of our life. Whether you are a one pot windowsill gardener, purchaser of fresh herbs at the local farmstand or worker in your own garden plot, you can expand your sense of the versatility of herbs.
