What is the name of the cultivar Pinus strobus 'Nana' commonly known as?

The cultivar Pinus strobus 'Nana' is commonly known as Dwarf White Pine. This name is derived from the species name, Pinus strobus, which is recognized as the Eastern White Pine. The term 'Nana' denotes its dwarf nature, indicating that this cultivar will grow to a smaller size compared to the standard Eastern White Pine, making it suitable for ornamental use and smaller landscapes. The dwarf form is characterized by its dense, bushy shape and soft, flexible needles, which contribute to its popularity in gardening and landscaping.

The other options do not refer to this particular cultivar. Dwarf Mugo Pine pertains to a different species entirely, and Bird's Nest Spruce and Japanese Garden Juniper are distinct plants, each with unique characteristics and uses. Understanding these distinctions is essential for proper identification and use in horticulture.
