Engelmann’s Prickly Pear


Engelmann’s Prickly Pear (Opuntia engelmannii) is common across the Southwestern United States and into Mexico. At the base of the nearby west-facing foothills of the Sandia and Manzano mountains of central New Mexico it can be found growing in association with Gray Oak, Turbinella Oak, Pinon Pine, Rocky Mountain Juniper, Mahonia, Tree Cholla, and Bear Grass. Engelmann’s Prickly Pear is also commonly called Texas Prickly Pear, Desert Prickly Pear, Prickly Pear, and Nopal.


Engelmann’s Prickly Pear forms clumps 3’ to 4’ tall and wide or larger. Engelmann’s Prickly Pear does not form stalks, like yuccas, but adds new prickly pear pads annually to existing pads.
 
Pads are normally a pale green color and can have a diameter of up to 12”.
 
 
Engelmann’s Prickly Pear has long white or yellow spines and clusters of smaller hair-like spines called glochids. Each cluster contains numerous glochids that easily come off into the unprotected skin and causes irritation. Glochids may be difficult to see but you can definitely feel their presence. They can be easily removed with tweezers.


Engelmann’s Prickly Pear produces yellow flowers in spring or early summer.


Red-purple fruits called tunas form by summer.

 
Tunas of Engelmann’s Prickly Pear are edible after removing any surface spines or glochids. This is easily done by burning them off over a fire. Fruits are also used to make jelly, cactus candy, and syrup.


Engelmann’s Prickly Pear is a low maintenance, colorful addition to any hot, dry, landscape. It needs only occasional watering during summer. It is also useful as a defensive perimeter anywhere you want to discourage movement, under windows, walkways, or walls. Eventually your prickly pear may need reduction in size. This is easily done using Barbeque (BBQ) Tongs and Pruning shears. Hold the pad with BBQ tongs and cut pads at the point of connection to another pad.


Over winter Prickly Pear pads droop. Winter droop (wilt) is normal and does not indicate any growth problems. As the warmth of spring returns and water movement within the plant resumes your prickly pear will again perk up.

Engelmann’s Prickly Pear is best grown in full sun, with low water, and is hardy to USDA zone 6.

Weed Identification: Goatheads or Stickers

Goatheads (Tribulus terrestris) are native to Southern Europe, Asia, Africa and Australia. Goatheads are also called stickers, sticker weed, bullhead, devil’s weed, and puncturevine. Goatheads are easily recognized by their prostrate growth form,

leaves with leaflets,


yellow flowers,

and stickers (Goatheads).

If you miss’em visually then they will stab you painfully in the fingers as you work your garden, or stick to your clothing and shoes. Goatheads are the primary reason local bicyclists must get “thorn proof” tires for riding on area trails and streets.
Goatheads have prostrate stems that radiate outward from one central point. Leaves are compound with smaller leaflets. Lemon yellow flowers form along the stems and fertilized flowers form fruits.Fruits consist of several attached structures called nutlets (Goatheads).

Each nutlet is a single seed that becomes hard or woody when mature. Each seed has two sharp spines that easily penetrate skin, clothing, and soles of shoes. This att…

Western Soapberry Tree

The Western Soapberry tree (Sapindus saponaria var. drummondii) is native to New Mexico. It grows wild from Missouri, Arkansas, and Louisiana westward through Texas, Oklahoma, Kansas, Colorado, Arizona, and Mexico. The fruit of the Western Soapberry tree is a drupe.


Mature fruits are translucent, amber colored, and contain a black seed.

The mature fruit without the seed


will produce a good lather with water


and has been used as a soap substitute.


Fruits persist on the trees through winter. The Western Soapberry tree can grow 1′-2′ annually reaching 25′-30′ tall and wide making it a good sized shade tree. Fall leaf color is an attractive golden yellow. Currently, there are no improved varieties of the Western Soapberry Tree.


It grows well on the alkaline soils of New Mexico and is very tolerant of heat and drought once established. This tree is rarely affected by disease or insect pests making it an ideal specimen tree for your yard or landscape. Soapberry leaves are pinnately compound w…

Afghan Pine

The Afghan Pine (Pinus eldarica) is also known as Desert Pine, Eldarica Pine or Mondell Pine. Afghan Pineis native to low rainfall areas of Afghanistan, Pakistan, and southern Russia. In fact, when planted in areas of high rainfall (> 20” per year), it becomes susceptible to a number of diseases and rapidly declines. This problem has occurred in East Texas. The Afghan Pine thrives in heat, wind, and tolerates drought. Afghan Pine must be planted in soils with good drainage like sand. It is not suitable for poorly drained heavy clasy soils.

Afghan Pines are generally pyramidal or Christmas tree shaped in form when young
becoming more oval or irregular with age.

The leaves of the Afghan Pine are evergreen needles usually found in groups of 2 per fascicle or sheath.

Needles are shed after several years and make excellent mulch as they fall around the trees base.
It has attractive trunk bark that becomes dark and furrowed with age.

Afghan Pines can add 1′-2′ new growth per year and reach 40…
