How could I have forgotten to add Aquilegia chrysantha (the former wildflower of the Big Bend region of Texas that has taken gardens by storm), petunias and their cousins, Nicotiana alata and sylvestris? Old-fashioned ornamental poppies, P. somniferum descendants, come up voluntarily, too. A relative newcomer, Brazilian basket-flower is good about reseeding, as are portulacas. There is an occasional snapdragon and a very occasional dianthus, but don't count on them. Queen Anne's lace would germinate, too, if anyone were brave enough to grow it.
