By Russ Allen You would probably never have guessed that some of the most beautiful new daylilies were created by gardeners located in our very own Southern New England area! To illustrate this, the author went on the following quest to highlight some of them for you. BackgroundDaylilies (also referred to as the “perfect perennial”) are quite amenable to hybridizing by local gardeners to create gorgeous new varieties. The performance of daylilies (such as bloom quantity and quality, multiplication rate, weather tolerance, etc.) can vary widely depending on the climate zone, so selecting daylilies that are outstanding performers in one’s geographic area is important. The QuestSince the author lives in…

Invasive Princess Tree
Princess tree (Paulownia tomentosa) is a fast-growing 30-60 foot deciduous tree native to China that spreads by releasing thousands of tiny winged seeds in the fall. It’s considered invasive and is banned in Connecticut. It is illegal to import, move, sell, purchase, transplant, cultivate or distribute. Also called Empress Tree and Royal Paulownia, it was named after Anna Pavlovna, the daughter of Czar Paul I. It was brought to Europe in the 1834 by the Dutch East India Company and made it to North America in 1844. The seeds were used as packing material by Chinese porcelain exporters before the advent of polystyrene. It was reportedly touted as a wonder…

Elm Zigzag Sawfly Found in the Berkshires
According to UMass Amherst, elm zigzag sawfly (Aproceros leucopoda) has been found in Berkshire County in western Massachusetts and Hampden County in south-central Massachusetts. Sometimes called EZS, it’s native to Eastern Asia but is now considered invasive in Europe and North America. It was first detected in North America in Sainte-Martine, Quebec in 2020 but has since been spotted in Maryland, Massachusetts, New York, Pennsylvania, Vermont and Virginia. The larvae of this sawfly can cause defoliation of host trees (Ulmus spp.) as the larvae feed on leaves. This could exacerbate the decline of elm trees already threatened by Dutch elm disease (Ophiostoma ulmi). It is unclear at this point which…

Something Wilting This Way Comes
Oak wilt was spotted nearby in Brooklyn and Long Island in 2016. It’s a serious vascular disease caused by a fungus (Bretziella fagacearum) that threatens oaks. The fungus penetrates the xylem and restricts the flow of water and nutrients up toward to leaves. It was first described in Wisconsin in 1944. Two other vascular diseases you’ve probably heard of are Chestnut Blight and Dutch Elm Disease. Bad company. Oak wilt can be spread by insects and root-to-root contact with other oak trees. The human movement of firewood is another important vector. The symptoms include leaf discoloration, leaf wilt, defoliation and death of the tree, which can occur in just one…

Creating an Outdoor Tree Museum
By Charlie Stebbins An “Arboretum” is an outdoor “tree museum,” open to the public and offering a verdant sanctuary of quiet and beauty. With forests worldwide threatened by development, invasive pests, diseases, and plants, plus poor management practices, the need for quality “arboreta” was never so pressing. Fortunately, the expanding community of tree-loving enthusiasts grows increasingly strong! Arboreta have been around since Roman times and today they total about 4,000 globally. Botanical gardens feature herbaceous flowers and grasses, while trees and woody shrubs are the stars in an arboretum. Long ago, arboreta were simply “places of trees,” randomly arrayed in old cemeteries, universities or municipal parks. Documentation, landscape legacy, and…

In Search of an Improved Inkberry
By Michael Dirr Ilex glabra, inkberry or gallberry, one of best native broadleaf evergreen shrubs, is used extensively in contemporary landscapes from Maine to Georgia and throughout the Midwest. The native range extends from Nova Scotia to Maine, south along the coast to Florida and west to Texas. According to the Florida Native Plant Society, the species grows in low flatwoods, seeps, coastal swales, bogs and sinks. I observed the species in wet areas on Cape Cod where it formed suckering colonies and in low flatwoods in the Okefenokee Swamp in South Georgia. Bonnie and I were hiking In the Okefenokee through thickets of this and Aronia arbutifolia and all…

Phlox paniculata ‘Jeana’
Phlox paniculata ‘Jeana’ is the Perennial Plant Association’s Perennial Plant of the Year for 2024. ‘Jeana’ was named for Jeana Prewitt who found it growing along the Harpeth River near Nashville, Tenn. Featured photo courtesy of Prides Corner Farms (pridescorner.com) “I love Phlox paniculata ‘Jeana’ and it is my go-to variety in my garden designs,” says Nancy DuBrule Clemente from Natureworks in Northford, a longtime friend of the magazine. “It does attract tons of pollinators, especially tiger swallowtail butterflies galore. If you deadhead it, it blooms and blooms. It really is superior. The panicles are longer and more pointed which makes it distinctive.” It’s resistant to Powdery Mildew and makes…

Support Your Local Orchard
By Russell Steven Powell This story first appeared in the Orchard Blog at newenglandapples.org Highly variable is about the best way to describe the 2023 New England apple crop.Most people by know now that the fresh apple crop will be significantly smaller due to a region-wide freeze the night of May 18. Yet many orchards have full crops, and most have some apples. When all the apples are picked, though, losses could amount to as much as half of a normal crop of between 3.5 million and 4 million 42-pound boxes. It means there will be plenty of fresh apples this fall, but the season may not last as long,…

Castor-Aralia: A Thorny Threat
Castor-aralia (Kalopanax septemlobus) is a deciduous tree native to Eastern Asia (China, Japan and Korea). Its common names include Tree Aralia and Prickly Castor Oil Tree. It can have thorns up to a half inch long and a trunk five feet in diameter. It may look tropical but it’s actually cold hardy to about -40ºF. It’s recently been found growing wild in several places in Connecticut. GoBotany (gobotany.nativeplanttrust.org) says it’s been spotted in Massachusetts and New Hampshire. University of New Hampshire scientists have traced the spread of this exotic tree in local forests to a single tree planted on campus in the early 1970s. According to the UNH Today website…
