WEED IDENTIFICATION: SAND BUR


Sand Bur (Cenchrus longispinus) is native to North America. It has other names like sand spur,
long-spined sand bur, hedgehog grass, and bur grass. Sand Bur is an annual grass usually growing with a prostrate growth form. It is similar in appearance to other grasses prior to seed formation. Individual plants may be 3’ in diameter, sometimes larger. 


Sand Bur is a common weed of sandy soils but also grows well elsewhere. Sand Bur will often root at stem nodes that are touching the ground. The root system of Sand Bur is shallow and fibrous making them easily pulled (when immature).


Sand Bur produces a flowering spike. As seeds begin to form Sand Bur is easily recognized by its numerous sharp or burred seeds or long spines.


As the burred seeds mature they are easily separated from the mother plant and their sharp spines stick to virtually anything. Sand Bur can disseminate its seeds long distances because its sharp spines will hitch a ride on skin, animal hides, shoes, and clothing.


Sand Bur can be removed without the need of chemicals. Simply pull up the young plants. It is essential to pull them when they first identified by their burred seed spikes. At this time the burred seeds are green and the spikes are softer and less likely to separate from the mother plant. Pull them at this time using gloves, a fork, or a shovel and you will be able to remove the plant along with all its seeds.


Removing plants in this manner a couple times per season for a couple seasons and you will be able to rid your yard of this prickly pest.

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
