Trees That Please Nursery: 30 Days of Fall Foliage, Monday November 19th.


Jujube

 

The Jujube tree (Ziziphus zizyphus) is also known as the Chinese date, red date, or just Jujube. It grows as a small to medium sized tree or shrub reaching 15’ – 20’ tall and 10’ – 15’  wide.  With regular water it can add 2’ – 3’ of growth annually. The leaves are a glossy-green so it makes a very beautiful canopy. Branches usually have spines approximately 1 inch in length. Flowers are produced in spring and summer on branches throughout the tree.

The Jujube tree produces a small fruit that varies in size depending upon variety. Fruits can be round to oblong or egg shaped. At maturity, fruits are brown skinned and look like little apples. Fruits may be eaten at this time and are similar to an apple but less sweet and juicy. After the season’s first frosts the fruits shrivel and turn a darker reddish brown. The shriveled fruits are typically sweeter and chewier, resembling “dates”.  Jujube fruits have elongated seeds that resemble those of dates.


With the onset of fall Jujube foliage shows little color change or sometimes a bit of yellow. It is more common for Jujube leaves to continue growth until the first frosts. At that time leaves die and appear dehydrated while still attached to the tree. Winds will then take them from the tree.


After leaf fall you can observe the crooked branch structure,


and spines


which gives them winter interest especially if some fruits remain attached.


The Jujube tree is a nice ornamental that grows well in the high desert climate. They are best grown with low to regular water and tolerate most soils. Jujubes are hardy to USDA zone 5. They are very heat and drought tolerant.

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 penetrat

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. T he 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. S

Afghan Pine

The Afghan Pine ( Pinus eldarica ) is also known as Desert Pine, Eldarica Pine or Mondell Pine. Afghan Pine is 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. Af
