hazelnut Corylus americana Kingdom: Plantae FEATURES Division: Magnoliophyta Hazelnut is also known as American filbert. This Class: Magnoliopsida perennial shrub has leaves arranged alternately Order: Fagales along the twigs. The simple, double-toothed leaves are oval in shape. Leaves turn yellow, orange and red Family: Corylaceae in the fall of the year. The gray twigs and leafstalks ILLINOIS STATUS are covered with hairs. Green male and female flowers are borne on the same plant. The male common, native catkins are one to four inches in length and appear © Mary Kay Solecki before the leaves begin to unfurl. Catkins persist on the tree through the winter. The female flowers lack petals. Clustered near the twig tips, the bright red, female flowers are one-fourth inch wide. The fruit is a nut. The bristly nut husk is open at one end. Fruiting begins at about age six years. BEHAVIORS The hazelnut may be found throughout Illinois. It grows in moist prairies, fence rows, edges, dry woods and thickets. Flowers are produced in March and April. The seeds, leaves, stems and buds of this plant are eaten by wildlife. Hazelnut grows in small, shrubby groups because it sends up new plants from the roots. The flowers are pollinated by the wind. leaves ILLINOIS RANGE leaves and fruit © Illinois Department of Natural Resources. 2020. Biodiversity of Illinois.

Nut Trees - 2021
NUT TREES - 2021 CHESTNUT – Chinese Castanea mollissima ‘Improved’ (Seed grown) #3 #7 pot A selection from a superior orchard strain with unusual vigor, uniformity, disease-resistance and superior nut production. At least two seedlings or cultivars must be planted within 100 to 200 feet of each other to ensure cross-pollination and optimal fruit set. Seedlings commonly bear fruit in four to seven years. Mature trees may yield 35 to 55 pounds of nuts each year. Grows 30- 60 feet tall and 25 feet wide. PECAN Carya illinoinensis Pollinate with another variety of pecan for bigger crops. Grows 50' tall or more. ‘Kanza’ (Grafted) #3 pot Quality nuts that ripen before other varieties. Superior cold hardiness, disease resistant. 52% kernel. Grows 70' tall, 40-75' wide. ‘Lakota’ (Grafted) #3 pot High-quality nuts shell easily yielding cream-to-golden kernels with rich flavor. Early maturing. Strong, wind-resistant tree, disease-resistant to pecan scab. Ripens in mid- to late-October. ‘Peruque’ (Grafted) #3 pot Early season producer derived from a selection of native seedlings near the Mississippi River. Average production is 81 nuts per pound, with 59% kernel. Kernels are golden, with tight dorsal grooves and a deep basal cleft. Grows 70' tall, 40-75' wide. Native. AMERICAN FILBERT #3 pot Corylus americana Native shrub, excellent for naturalizing, woodland gardens and shade areas.

Some, like the false Indigobush, silky and red-osier dogwoods, spicebush, and elderberry, can tolerate wet soils. None do well on dry sandy or rocky soils. • All prefer at least 3 hours of sun per day, and flower better when they can get 6 hours or more per day. Spicebush can tolerate full shade, but flowers better with 3-6 hours of sun.

Rutgers University The American Chestnut Society Annual Meeting October 22, 2011 Nut Tree Breeding at Rutgers Based on the tremendous genetic improvements demonstrated in several previously underutilized turf species, Dr. C. Reed Funk strongly believed similar work could be done with nut trees Title of project started in 1996: Underutilized Perennial Food Crops Genetic Improvement Tom Molnar and Reed Funk Program Adelphia Research Farm August 2001 Nut Breeding at Rutgers Starting in 1996, species of interest included – black walnuts, Persian walnuts and heartnuts – pecans, hickories Pecan shade trial – chestnuts, Adelphia 2000 – almonds, – hazelnuts We built a germplasm collection of over 25,000 trees planted across five Rutgers research farms – Cream Ridge Fruit Research Farm (Cream Ridge, NJ) – Adelphia Research Farm (Freehold, NJ) Pecan shade trial Adelphia 2008 – HF1, HF2, HF3 (North Brunswick, NJ) Nut Breeding at Rutgers Goals – Identify species that show the greatest potential for New Jersey and Mid- Atlantic region – Develop breeding program to create superior well- adapted cultivars that reliably produce high- quality, high-value crops • while requiring reduced inputs of pesticides, fungicides, management, etc. Nut Breeding at Rutgers While most species showed great promise for substantial improvement, we had to narrow our focus to be most effective Hazelnuts stood out as the species where we could make significant contributions in a relatively short period of time – Major focus since 2000 Hazelnuts at Rutgers Why we chose to focus on hazelnuts: – success of initial plantings made in 1996/1997 with few pests and diseases – short generation time and small plant size (4 years from seed to seed) – wide genetic diversity and the ability to hybridize different species – ease of making controlled crosses – backlog of information and breeding advances – existing technologies and markets for nuts Hazelnuts: Corylus spp.

Landscaping Near Black Walnut Trees
Selecting juglone-tolerant plants Landscaping Near Black Walnut Trees Black walnut trees (Juglans nigra) can be very attractive in the home landscape when grown as shade trees, reaching a potential height of 100 feet. The walnuts they produce are a food source for squirrels, other wildlife and people as well. However, whether a black walnut tree already exists on your property or you are considering planting one, be aware that black walnuts produce juglone. This is a natural but toxic chemical they produce to reduce competition for resources from other plants. This natural self-defense mechanism can be harmful to nearby plants causing “walnut wilt.” Having a walnut tree in your landscape, however, certainly does not mean the landscape will be barren. Not all plants are sensitive to juglone. Many trees, vines, shrubs, ground covers, annuals and perennials will grow and even thrive in close proximity to a walnut tree. Production and Effect of Juglone Toxicity Juglone, which occurs in all parts of the black walnut tree, can affect other plants by several means: Stems Through root contact Leaves Through leakage or decay in the soil Through falling and decaying leaves When rain leaches and drips juglone from leaves Nuts and hulls and branches onto plants below. Juglone is most concentrated in the buds, nut hulls and All parts of the black walnut tree produce roots and, to a lesser degree, in leaves and stems. Plants toxic juglone to varying degrees. located beneath the canopy of walnut trees are most at risk. In general, the toxic zone around a mature walnut tree is within 50 to 60 feet of the trunk, but can extend to 80 feet.
