arboretum
An arboretum (latin plural: arboreta) is a botanical collection of trees and shrubs; a living museum of trees and woody plants, grown and cared for by an organization committed to their stewardship.
I’ll never be able to afford one but heres my digital effort:
sequoia sempervirens
This species includes the tallest living trees on Earth, reaching up to 116.22 m and up to 8.9 m in diameter.
The species is monoecious, with pollen and seed cones on the same plant.

hesperocyparis macrocarpa
A medium-sized coniferous evergreen tree, which often becomes irregular and flat-topped as a result of the strong winds that are typical of its native area.
