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,
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
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.
mature fruit without the seed
will produce a good lather with water
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 (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.
Pines are generally pyramidal or Christmas tree shaped in form when young becoming
more oval or irregular with age.
leaves of the Afghan Pine are evergreen needles usually found in groups of 2
per fascicle or sheath.
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.
Pines can add 1′-2′ new growth per year and reach 40…
