Watch out for this plant -- Branched Broomrape

Although pretty, Branched Broomrape is a parasite and endangers crops. It grows 4 to 12 inches tall and has snapdragon-like blooms.
If you see it get a plastic bag and then pull it and immediately seal it in the bag without walking around (to avoid distributing its tiny seeds, as many as 50,000 per plant!). It can lie dormant for decades. It grows by attaching to the roots of other plants to gain water and nutrients. The Fort Worth Star Telegram reported today that Tarrant County is now the furthest northwest that it has been spotted. A botanist at Fort Worth's Botanic Research Institute of Texas (BRIT) recently spotted it in a field along Interstate 20.
