Middletown Nature Gardens: The Middletown Nature Gardens is located off Randolph Road in Middletown, Connecticut.  In 1995, the city of Middletown, CT purchased the 18 acre of land and dedicated it open space.  This piece of land serves as a natural habitat to many plants and animals.  There are many trails to walk about surrounded by an array of diverse trees and shrubs.  Some of the types of trees and shrubs include red cedar, flowering dogwood, highbush blueberries, white pine, and speckled alder.  The main trail is a 0.5 mi loop.  Mulched side trails, which branch off the main trail, add another 0.5 mi to walk.  Community volunteers maintain the park.  They have erected many bluebird boxes and bat houses to house some of the natural wildlife of the park.  There are also vernal pools, which are habitats for salamanders and wood frogs in the southeast corner of the park.  There is even a 200-year-old sugar maple, which is called the “bee tree,” in which a large colony of bees has made it their home.

Aceratium: Aceratium is a genus of about 20 species of trees and shrubs of eastern Malesia and Australasia, constituting part of the plant family Elaeocarpaceae.  In Australia they are commonly known as carabeens.  They grow naturally in rainforests, as large shrubs to understorey trees and large trees.

Gymnosporangium sabinae: Gymnosporangium sabinae (also Gymnosporangium fuscum and other names) (pear rust, European pear rust, or pear trellis rust) is a fungal heteroecious plant pathogen with "Juniperus" (Juniper trees and shrubs) as the primary (telial) host and only "Pyrus" (pear trees) as secondary (aecial) hosts.  It is one of many types of rust fungi affecting plants.

GiST: In computing, GiST or Generalized Search Tree, is a data structure and API that can be used to build a variety of disk-based search trees.  GiST is a generalization of the B+ tree, providing a concurrent and recoverable height-balanced search tree infrastructure without making any assumptions about the type of data being stored, or the queries being serviced.  GiST can be used to easily implement a range of well-known indexes, including B+ trees, R-trees, hB-trees, RD-trees, and many others; it also allows for easy development of specialized indexes for new data types.  It cannot be used directly to implement non-height-balanced trees such as quad trees or prefix trees (tries), though like prefix trees it does support compression, including lossy compression.  GiST can be used for any data type that can be naturally ordered into a hierarchy of supersets. Not only is it extensible in terms of data type support and tree layout, it allows the extension writer to support any query predicates that they choose.  The most widely used GiST implementation is in the PostgreSQL relational database; it was also implemented in the Informix Universal Server, and as a standalone library, libgist.

Shrub: A shrub or bush is a small to medium-sized woody plant.  Unlike herbs, shrubs have persistent woody stems above the ground.  They are distinguished from trees by their multiple stems and shorter height, and are usually under 6 m (20 ft) tall.  Plants of many species may grow either into shrubs or trees, depending on their growing conditions.  Small, low shrubs, generally less than 2 m (6.6 ft) tall, such as lavender, periwinkle and most small garden varieties of roses, are often termed "subshrubs".

Diocirea: Diocirea is a genus of flowering plants in the figwort family, Scrophulariaceae.  The genus is endemic to a small area in the south-west of Western Australia and is intermediate in character between "Eremophila" and "Myoporum".  There are four members of the genus, all of which are small shrubs with stems and leaves which produce a resin making the plants appear bluish-green.  Neither the genus, nor any of the species had been described before 2007 although a few specimens had been collected as "Eremophila elachantha".  Despite their limited distribution, they often occur in populations of several thousand individual plants, forming a dense ground cover.

Jacquemontia: Jacquemontia (clustervine) is a plant genus in the morning glory family Convolvulaceae.

Myoporum: Myoporum is a genus of flowering plants in the figwort family, Scrophulariaceae (formerly placed in Myoporaceae).  There are 30 species in the genus, most of which are endemic to Australia although others are endemic to Pacific Islands, including New Zealand, and one is endemic to two Indian Ocean islands.  They are shrubs or small trees with leaves that are arranged alternately and have white, occasionally pink flowers and a fruit that is a drupe.

Artificial Christmas tree: An artificial Christmas trees is an artificial pine and fir tree manufactured for the specific purpose of use as a Christmas tree.  The earliest artificial Christmas trees were wooden, tree-shaped pyramids or feather trees, both developed by Germans.  Most modern trees are made of polyvinyl chloride (PVC) but many other types of trees have been and are available, including aluminum Christmas trees and fiber-optic illuminated Christmas trees.

George Landis Arboretum: The George Landis Arboretum is a public garden comprising hundreds of acres of which 40 are devoted to noteworthy collections and gardens overlooking the Schoharie Valley near Esperance, New York, United States.  The physical address is 174 Lape Road.  Forty acres of the Arboretum are developed with plantings of trees, shrubs, and herbaceous perennials from around the world, including approximately 2,000 labeled specimens.  The remainder of the property consists of natural areas, woodlands, wetlands, more than 8 miles of trails, and open fields.  Among the Arboretum's horticultural features are a labeled collection of nearly all the trees, shrubs and vines native to New York State, as well as collections of notable trees, flowering ornamental trees and shrubs, tough trees for tough sites, conifers, and oaks.  Two old growth forests and additional natural areas representing various stages of succession await visitors The Van Loveland Perennial Garden at the old farmhouse is a seasonal favorite.  Collection signage includes QR codes directed toward audio descriptions.
