Port Orford Cedar
Chamaecyparis lawsoniana
Port Orford Cedar is a large evergreen coniferous tree, typically found in its native range. It boasts scale-like foliage that is aromatic when crushed. The tree has a conical growth habit and can reach impressive heights in the wild. While highly valued for its timber and ornamental qualities, it is primarily an outdoor tree. Growing it indoors is extremely challenging due to its need for full sun, cold winters, and susceptibility to root rot in containers. People grow it outdoors as a specimen tree, for hedging, or in large gardens.
Purple Leaf Plum
Prunus cerasifera
The Purple Leaf Plum is a deciduous tree known for its striking purple foliage that persists throughout the growing season. It typically reaches a height of 15-25 feet with a similar spread. In spring, it produces delicate pink or white flowers before the leaves emerge. While primarily an outdoor ornamental tree valued for its vibrant color and spring blossoms, it is not suited for indoor cultivation due to its size and high light requirements.
