Lavender and pink Blooms-Texas Fall Aster, Wild Petunia and Pink Mimosa

Aster oblongifolius-  
Texas Fall aster- this is familiar name to me.









This is a tentative identification for me...newly named.
Low Ruellia?

Ruellia humilis - Acanthus family- wild petunia 

(Pink Mimosa) Mimosa borealis Gray

This silly plant, like our Redbud that bloomed thinks it is Spring.

Normally blooms in April, this is an October bloom!

 


A great book is by Brother Daniel Lynch, C.S.C. who taught Biology at St. Edward's University.
Native & Naturalized Woody Plants of Austin and the Hill Country.
Published in 1981, it may still be available at the St. Edward's bookstore where I bought it. 
I remember Brother Daniel. He was strident in his mission to keep Austin green with plants.
I remember the gayfeather or liatris he planted and nurtured at Blunn Creek Preserve.

He is largely responsible for Austin parking lots that have trees.
He lobbied City officials tirelessly to plant trees amidst the asphalt jungle. Thank you Brother Daniel.
