Tree InvasiveThis plant is considered invasive Acer platanoides 'Columnare' [Columnar Norway Maple] This cultivar is easy to transplant and is tolerant of different soils. The Columnar Norway Maple is more adaptable to drought than other Maples. Pollution tolerant. When Norway maple escapes cultivation and invades natural areas it reduces species richness and native tree regeneration by out-competing other trees and understory species for resources, creating dense shade canopies, and spreading rapidly through high seed production. It also releases toxins that reduce the growth and reproduction of native…
Tree Acer pseudoplatanus [Sycamore Maple] Tolerates salt spray. Produces a lot of dead wood that needs removal. Anthracnose and canker disease can be serious.
Tree Aesculus × carnea 'Briotii' [Ruby Red Horsechestnut] Has decent tolerance to drought and urban environments. Buds are not as sticky as its parent plant, Aesculus hippocastanum. Flower panicles are larger than both parent species with a rich red coloration, making it a popular tree choice in England.
Tree Aesculus hippocastanum 'Baumannii' [Baumann Common Horsechestnut] 'Baumannii' is known for its large panicles of double flowers. The flowers are sterile, so none of the large, littering, poisonous fruit of the species type are produced, increasing this tree's usability. Widely adapted to soils and environments; however, very dry conditions must be avoided. Leaf blotch often disfigures foliage.
Tree InvasiveThis plant is considered invasive Ailanthus altissima [Tree of Heaven] Unusual form and texture not unlike a large sumac. Highly adaptable. Tolerates salt spray. Dioecious. Coarse and inclined to drop twigs. Male flowers are malodorous; female plants make many weed seedlings. Ailanthus altissima forms dense, clonal thickets which displace native species and can rapidly invade fields, meadows, and harvested forests. This invasive tree species is extremely tolerant of poor soil conditions and can even grow in cement cracks. Ailanthus altissima is not shade tolerant, but…
Tree Amelanchier × grandiflora 'Cole’s Select' [Cole's Select Apple Serviceberry] Cole's Select Apple Serviceberry is an attractive plant with multi-seasonal interest, thick, glossy foliage, and especially outstanding red to orange fall coloration. 'Cole's Select' tends to have slightly larger flowers and stronger spreading, more horizontal branching than the species type. The beautiful white clusters of flowers give rise to sweet purple-black berries that are edible by humans and especially relished by birds. The fruits can be used in pies, jams, and jellies.
Shrub Indiana Native Amorpha fruticosa [Indigobush Amorpha] The Indigobush Amorpha is a Indiana native shrub that can be found along river banks and shallow marshes. This shrub can be planted in areas of poor soil where few other plants will survive, as well as used for erosion control. To avoid weediness, seeds can be collected shortly after flowering as it can spread readily by seeds. Common problems of Amorpha fruticosa includes rust, leaf spots, powdery mildew and twig canker. Some gall problems…
Shrub Indiana Native Arctostaphylos uva-ursi [Bearberry] Hard to establish, can develop winter burn from sun and wind when cold. Does not like excessive summer heat. Can develop foliar diseases (leaf spot) when stressed. Leaves are used to make a tea in some parts of Russia, where it is known as Kutai and Caucasian Tea. The dried leaves have been used to treat diseases of the bladder and kidney, and inflammatory diseases.
Shrub InvasiveThis plant is considered invasive Berberis thunbergii [Japanese Barberry] An adaptable plant that does well in an urban environment. Can be coppiced, with the resulting new growth developing better summer color. Can be pruned to ground every 5 to 7 years. Relatively trouble-free. Berberis thunbergii invades a variety of habitats from shaded woodlands to open fields and wetlands. Berberis thunbergii is rapidly spread by birds that eat the berries thus dispersing the seeds.
Shrub InvasiveThis plant is considered invasive Berberis thunbergii 'Bogozam' [sold as Bonanza Gold™] [Bonanza Gold Japanese Barberry] 'Bogozam' is noted for its golden yellow leaves and compact, dwarf habit. An adaptable plant that does well in an urban environment. Place in a high light location for best foliage coloration. Can be coppiced, with the resulting new growth developing better summer color. Can be pruned to ground every 5 to 7 years. Relatively trouble-free.
