I am sorry for this delayed reply to your gardening question as we are transitioning to a new Q&A system. I hope this reply is not too late to be of help.
Some annuals and perennials for shady spots in San Antonio include: persian shield, impatiens, wishbone flower, caladium, ferns, and Aztec grass (looks like white and green colored liriope).
Thanks for the question. Please stop in again soon!
