Gaura Lindheimeri....

....and I only know that because--for once--I left the marker in the pot when I brought this home from the garden center last spring. I had gotten several of these the spring before & they grew so well on their own that I bought them again this year as it's my kind of plant...needs no care, doesn't die, & blooms from spring through autumn!  
It's officially the first day of fall today--my absolute favorite season-- & what gorgeous weather we've been having--mid to high 70's, sunny & no humidity! If it were like this year round I'd be in heaven!!   :))
