Scientific: Populus mexicana (Synonym: Populus fremontii subsp. mesetae)
Common: Mexican popular
Family: Salicaceae
Origin: Mexico

Taxonomic note: The scientific name of this taxon is currently not fully resolved, though recent DNA evidence supports use of Populus mexicana [Liu et al. (2016). Frontiers in Plant Science, DOI:10.3389/fpls.2016.02022]

Pronounciation: POP-u-lus mex-i-KA-na

Hardiness zones
Sunset
7-24
USDA 7-11

Landscape Use: A large mesic shade tree, expansive lawn tree, golf course and park tree, riparian restoration.

Form & Character: Restful, oasis, suggestions of water. Somewhat more refined in appearance than Populus femontii because of its slightly finer texture due to having slightly smaller leaves.

Growth Habit: Deciduous, woody, broadleaf perennial tree. Like Populus fremontii, this tree is a fast grower 60-feet tall, upright, pendulous and narrow when young to spreading with age. Deeply ridged and furrowed trunk with age.

Special warning: Beware of superficial, protruding lateral roots, especially in lawn areas!

Foliage/Texture: Foliage thin and light green, triangular, cordate to deltoid, 1- to 2-inches long, finely serrate margins, thin petioles creates a shimmer in slightest wind; medium texture.

Flowers & Fruits: Dioecious, flowers insignificant, fruits a cap with copious discharges of "cotton".

Seasonal Color: Bright yellow to golden yellow foliar color in fall sometimes inconsistent in the lower desert because of warm fall and early winter temperatures.

Temperature: Tolerant

Light: Sun

Soil: Tolerant

Watering: Regular

Pruning: Easily manipulated and pruned in any fashion. Prune according to use.

Propagation: Easy to reproduce from stem or root cuttings.

Disease and Pests: Thought to be less prone to bacterial wet wood, trunk heart rot fungi than Populus fremontii.

Additional comments: A fast-growing tree that has more urban landscape value in terms of mesic landscape use potential than its mesic landscape analog(s), Populus fremontii or even maybe Dalbergia sissoo. Just keep in mind that this is a large tree that needs a big space to grow effectively.

My personal opinion: Someone just needs to grow this tree!
