In 1993, The Jepson Manual estimated that California was home to 4,693 native species and 1,169 native subspecies or varieties, including 1,416 endemic species. A 2001 study by the California Native Plant Society estimated 6,300 native plants.
Chamaecyparis and Thuja also provide hundreds of dwarf cultivars as well as trees, including Lawson's cypress. Dawn redwood is widely planted as an ornamental tree because of its excellent horticultural qualities, rapid growth and status as a living fossil.

Washingtonia filifera, the desert fan palm, [4] California fan palm, or California palm, [5] [6] [7] is a flowering plant in the palm family Arecaceae, native to the far southwestern United States and Baja California, Mexico. Growing to 15–20 m (49–66 ft) tall by 3–6 m (10–20 ft) broad, it is an evergreen monocot with a tree-like
Above the tree line, extreme winds preclude tree-like growth. [6]: 17 Constant winds hitting the plants limits their size and flattens their shape. [10] Small size or dwarfism is therefore an adaptive feature to the extremes, and most alpine plants are just a few inches tall.

It is also planted in New Zealand as an ornamental tree and, occasionally, as a timber tree. There, finding more favorable growing conditions than in its native range, and in the absence of many native pathogens, it often grows much larger, with trees recorded at over 40 m (130 ft) tall and 3 m (9.8 ft) in trunk diameter.
Tecoma stans is a semi-evergreen shrub or small tree, growing up to 10 m (30 ft) tall. [1] It features opposite odd-pinnate green leaves, with 3 to 13 serrate, 8- to 10-cm-long leaflets.
