Description and Growing Information
Flowering Period
| General Description |
| The tree form is tall and pendulous, with outstanding soft needles weeping down. The P. lumholtz pine is known to have the smallest pine cone in Mexico. Vibrant green with a yellow tint where the needles meet the fascles. |
| Landscape |
| This species is extremely hard to come by where it's naturally growing, it’s on the list of threatened species. This species has hit a decline due to timber logging in pine forests. If you were to find one, it would most likely be in the lower slopes of the sierra madre. Usually growing less abundant, these trees are not found in clusters. |
| Cultivation |
| Pinus lumholtzii needs warmer climates for optimal growth, and can withstand temps that go as low as -8. They are a full sun species, needing sandy well draining soil conditions. Where they are native they usually get 500-600mm of rain annually. This species thrives better in elevation of 1500-2900 meters. |
| Shape |
| Pinus lumholtzii has dense pendulous needles. Its overall form can be very sporadic. Some looked uniform, others looking obscure. No two look similar. |
| Growth |
| Medium |
| ID Characteristic |
| Pinus lumholtzii has fascles arranged in bundles of 2-3. Weeping down ward. Small rounded cones with scales that point out. Being one of the smallest cones on a pine in Mexico! |
| Pests |
