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 P. 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

USDA 7-11

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

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

Growth Habit: Like P. fremontii, this tree is a fast grower 60 feet, upright, pendulous and narrow when young to spreading with age. Deeply ridged and furrowed trunk with age. Beware of exposed surface roots 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 from cutting

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

Additional comments: A fast growing tree that has more urban landscape value in terms of mesic landscape use potential than P. fremontii. Just keep in mind that this is a large tree that needs a big space to grow effectively.

Personal opinion: Someone just needs to grow this tree!
