Some Recommended Trees for Planting

Any Fruit Tree – How great is this? Pollinators love the nectar and pollen while they increase fruit set allowing you to enjoy the resulting bumper crop. Be advised that ornamental fruit trees are mostly self-pollinating and therefore provide less support for pollinators, while heirloom or native fruits are very attractive.

Ashes (Fraxinus) – Most type of ash will do well in New Mexico and are anywhere from a medium to large tree shade tree in size. The Arizona ash being the most common. Ash trees are presently not being recommended for planting owed to the Emerald Ash Borer, a pest that has eliminated all but a few of the mature ash trees throughout the upper Midwest United States. However, there are varieties that appear to be less susceptible to the borer and they are still available in local nurseries and provide great habitat for pollinators and shade for human beings. If you plant an ash, watch for “D” shaped openings along the trunk. This is a sign of the emerald ash borer having entered your tree. This tail-tale sign is not difficult to observe. If you see it and suspect your tree has them, contact your County Extension Agent immediately to notify them.

Big Tooth Maple (Acer grandide ntatum) – Growing 20-30’ tall and a native maple of New Mexico, this small to medium sized shrubby tree has spring blossoms hanging in clusters of yellow and green that appear with the leaves in March/April. It is both cold and heat tolerant and provides beautiful fall color in yellows and russet reds.

Bur Oak (Quercus macrocarpa) – This oak will grow 60 to 70’ tall with almost as wide a canopy. Its inconspicuous blossoms in April are a great source of food for pollinators and its fall acorns an excellent food source for other wildlife. It is tolerant of drought and both dry and clay soils.

Chokecherry (Prunus virginiana) – A small tree that works well as an understory tree with requiring only 6 hours a day or filtered sunlight. It blossoms in spring with white weeping spires. The fruits although mostly pit, make an amazing jelly and syrup.

Honey Mesquite (Prosopis glandulosa) – Yes, the mesquite flowers early in the season provide an early source of pollen, but this tree cannot survive extremely cold temperatures and will do best only in the southern regions of New Mexico. It is a relative of the New Mexico Locust (Robinia neomexicana) and other locust varieties also known to be great trees for pollinators. Most of them are also good at building healthy soil as they naturally add nitrogen through their root’s interaction with air, water and carbon.

Catalpa (Catalpa sp.) – Catalpa trees have large heart shaped leaves and provide a lot of shade that can inhibit grass from growing beneath them. In late spring and early summer, they have large showy white blossoms that pollinators feast on. These blossoms produce long dark brown seed pods that feed birds and other wildlife throughout the late fall and winter. While they are a good habitat tree, they require supplemental watering and heat stress can cause them to defoliate during intense summer temperatures. They grow 40-60’ tall and 20-40’ wide so makes sure you plant them where there is plenty of room.

Chaste Tree (Vitex agnus-castus) – Native to India and growing 15 to 20’ tall, this multi-stemmed tree (or small shrub if you prefer) will provide beautiful long purple or white spires of tiny blossoms when the summer becomes the hottest and driest. You will see purple to pink to white blossoms and will hear the many species of bees feeding on them. Because it waits till the very heat of the summer, it provides a food source for pollinators when it is most needed.

Chankapin oak (Muehlenbergii) – One of the faster growing oaks, this is also a great tree to plant as a resource for pollinators. Its April blossoms are narrow clusters in spring that provide dark colored acorn fruits in the fall.  They are a wildlife favorite. A native of New Mexico and long living, this oak will grow to about 40’ tall and almost as wide with rough scabby bark.

 Crepe or Crape Myrtle (Lagerstromia indica) – A small (15 to 20’ tall) multi-stemmed tree with deep burgundy, purple, pink or white blossoms that bloom all summer long. Unusually late in leafing out, this tree adds color and character to the landscape and blooms from early July through September. Once mature (10 to 12 years) its bark becomes uniquely smooth patches of different shades of tan and gray adding striking interest to the landscape.

Golden Raintree (Koelreuteria paniculate) – With long multi-branching yellow spires of blossoms in early to mid-summer, this tree provides an excellent food source for pollinators at a time when most trees have long stopped feeding them. Originally from the Asian continent and highly adaptable to varying soils and environments, it has become a popular landscape tree throughout the US. Considered a medium sized shade tree it will grow from 25 to 40’ tall. It can tolerate dry alkaline soil, something we have a lot of in New Mexico.

Honey Locust (Gleditsia triacanthos f. inermis)The native honey locust has large protruding thorns, but there is a thornless variety of this tree worth considering. From the pea family, it grows to 70’ and can provide blooms for pollinators in late spring/early summer with seed pods following for birds and other creatures over the fall/winter. Its branches are sturdy with small leaves that turn a golden yellow in fall. They require little to no raking and break down quickly over the dry NM winter.

Japanese Pagoda (Sophora japonica) – Also called the scholar tree, this tree is especially valuable to honeybees in mid to late summer when little else is blooming. Profuse white blossoms make it an attractive tree for the home landscape. Of Asian origin, once established it adapts well to New Mexico’s soil and temperatures and can be very hearty in the upper regions of the state.

Kentucky Coffee Tree (Gumnocladus dioicus) – A new tree also from the pea family that is being introduced to the SW, this tree is large and a great one for shade. It is drought and pollution resistant. The inconspicuous flower clusters appear in May/June when most of the other food providing trees have stopped. This makes the coffee tree a valuable option for providing a full growing season habitat. It has a lovely smooth dove gray colored bark and can endure the extreme temperatures experienced throughout New Mexico and will grow 60 to 70’ tall with a canopy 40 to 50’ wide.

Lacebark Elm (Ulmus parvifolia) – A beautiful medium to large shade tree, it is known for its beautiful patchwork bark. This tree is hearty and heat and drought tolerant. Unlike the Siberian elm (often mistakenly called the Chinese elm) it is not susceptible to Dutch elm disease and does not set prolific seed during high spring winds. This elm blooms and seeds in late summer/early fall when pollinators are storing up for winter and need a really good food source. Its leaves are small to medium in size, breaking down easily over the southwestern winter and turn a lovely bright yellow in the fall.

Linden (Tilia sp.) – Not a native to our state but one that adapts fairly well to the New Mexico environment, lindens bloom in midsummer, so they are an important nectar bridge during the hottest months and may be an emergency food source if spring blooms are lost to late frosts. Honeybees that harvest pollen from the Linden make a wonderfully rich honey. A linden will grow 65-130’ tall with lovely smooth grey bark. This is a large tree so plant it where there is lots of room.

New Mexico Olive (Forestiera pubescens) – A native of northern NM, this small tree/large shrub is hardy once established. It prefers to be multi-stemmed. When the female is in bloom you will only know it for the sound of bees gathering pollen at a time when little else is available. The fall fruit is small, football shaped, a dark purple and provides the birds food throughout the winter.

Western or Oklahoma Redbud (Cercis canadensis) – A small tree reaching only about 25’, each spring it provides a profusion of vivid fuschia colored blossoms.  These blossoms are early food for bee populations and develop into light brown pods that birds will and other wildlife will feast upon. Its leaves follow and are heart shaped.  early spring before its heart-shaped leaves appear. It prefers to be multi-trunked but can be pruned to a single stem.

Tatarian Maple (Acer tataricum) – A small tree, this maple will only get about 20’ tall.  But it can spread its canopy more than 25’ and it grows faster than many other trees. Small white flowers will attract bees to this small shrubby maple and are followed by winged seeds helicoptering to the ground a little later. One recommended cultivar of this species is the Hotwings® maple with its colorful red seeds and red fall foliage. It was developed for alkaline soils of the Rocky Mountain west.

Texas Mountain Laurel (Sophora secundiflora) – This small multi-stemmed tree belongs to the pea family and produces bright purple clusters that hint of grape soda in March/April. Pollinators love them. Its size varies and can reach 15’ tall and 10’ wide. It grows best where the environment is hot and dry. It is not cold hearty and grows best in the lower half of the state.

Tulip Poplars (Liriodendron tulipifera) – Native to eastern US and somewhat uncommon in New Mexico the tulip poplar adapts well to many climates and grows fast. It is a hard wood tree, unlike other poplars, and its growth habit is straight and tall to about 100’ or more at maturity, it needs a lot of room to grow. Its bark is dark brown and furrowed. Deep red winter buds are followed in April-May by lovely yellow blossoms that resemble a profusion of tulips unfolding. It provides an abundance of food for pollinators and is beautiful in the landscape.

Utah Serviceberry (Amelanchier utahensis) – More a small shrub than tree, this hardy multi-stemmed plant produces lovely white blossoms in earliest spring just as the ground begins to thaw and pollinators are desperate for something to feed on. And its leaves turn a brilliant red in fall.

 Willow (salix spp.) Not recommended in urban landscapes!  There are many types of willow, and they come in all shapes and sizes. All willows produce catkins (like pussy willow) in early spring. Catkins are rich in nectar and pollen and willows provide great habitat for not only pollinators, but also many other beneficial insects. Willows are also often the first tree to leaf out. Warning! Do not plant a willow over or near water pipes or a septic system. They love water and will search for leaks and openings in plumbing.
