Remarks
I grow plantago asiatica easily in my backyard.  They propagate like weeds and will grow best in between cracks of rocks.  The seeds dropped in the fall will sprout in the spring.  They do require frequent watering and does pretty well in shaded areas.  The Texas summer heat will slow its growth and even killing it.  But enough seeds would have already been produced to ensure a plentiful crop the next Spring.  Cooking: I use the entire plant in stew.   I cut off the root just because it's easier to clean.  The roots are edible and can be cooked with the leaves, flower, and seeds.  It must be boiled for at least 20 minutes to be tender enough to chew.  It is very fibrous.  I often use it as an antibiotic to treat coughs, ear infections, or just the common cold.  It tastes like a cross between kale and spinach.
