    Spring Ephemerals

    11:00am-12:00pm

    Bellevue Botanical Garden, The Aaron Education Center

    Presented by Cathy Atkins (NPA Board Member)


    Join us for a hands-on workshop and discussion of spring ephemerals — those fleeting, early-season woodland bloomers that light up the garden before the tree canopy leafs out.

    Each attendee will plant a biodegradable bag with soil and a curated mix of ephemeral bulbs and corms, ready to take home. Simply pop the whole pot directly into your garden bed — no transplant shock, no fuss — or tuck it into a decorative ceramic pot for a season of blooms on your porch or patio.

    We'll be planting a mix of:

    • Anemone blanda 'Blue Shades'
    • Anemone 'Charmer'
    • Border Blue Blend
    • Ornithogalum umbellatum (star-of-Bethlehem)
    • Crocus
    • Trientalis latifolia (western starflower) / Lysimachia borealis

    NPA Members - $15.00

    Non-Members - $25.00

    Class is limited to 30 participants. The fee for this class is non-refundable. If cancelled by NPA, you will receive a full refund.

    Matrix Planting for Home Gardeners

    Presented by:  Deborah Chud, 

    Matrix planting is naturalistic gardening in its purest form. Popularized by Piet Oudolf, this landscape design model uses perennials and grasses to explicitly imitate the structure of a meadow. All naturalistic gardening borrows from meadows to some degree, but matrix planting makes the imitation the point.

    In this richly illustrated presentation, Deborah Chud brings matrix design down to the scale of the home garden. She begins by asking why meadows look the way they do, then analyzes the features that matter most when we try to recreate them in a garden. From there, she reveals the key to successful matrix plant combinations and explains the embellishments that add complexity and seasonal interest.

    The presentation is more than a lesson in concepts. It is also the story of Chud's own matrix experiment, told through a series of gorgeous professional photographs. She closes with a step-by-step chronicle of how the planting was made and shares the results.

    Deborah Chud is a retired Massachusetts physician turned landscape designer, consultant, and educator. Her nine years of research on New Perennial gardens, including New York's High Line, produced a unique database of plant combinations and inspired her own highly unusual garden, a "must see" for Massachusetts garden clubs and a data source for a Boston University study of pollinator activity. In 2020, she presented her research in "Piet Oudolf: How Does He Do It?", an international event organized by Oudolf's co-author, Noel Kingsbury. Since then, she has given more than 70 talks, including at the Arnold Arboretum, the U.S. Botanic Garden, and the Toronto Botanical Garden. Chud lives in Chestnut Hill, Massachusetts.

    A graduate of Harvard College (A.B. 1972) and Boston University School of Medicine (M.D. 1984), Chud lives in Chestnut Hill, Massachusetts. She designs Boston-area gardens, coaches home gardeners in person and online, and offers design consultations across the country.

    Non-members - $15
