Yes, those are nandina.
Where all the flowers are use to be patio. We live in the country, no sidwalks and driveways, for kids to play basketball, roller skate etc. so we put in a huge patio. Once they married and left home, We cut out 3/4 of the patio and make it a garden. I had to have it fenced because of dogs and horses. I was surprised how many flower plants horses will eat:)

You certainly did a great job. Looks like a lot of work. All our kids are gone also. We bought the new house last year and got a big lot just so we could put in flowerbeds and vegetable garden, trees etc. We considered a pool but with the closest grandkids over 12 hours away we knew we wouldn't get the use out of it to justify the expense and trouble so we're just shooting for a retreat in our backyard, it's just going to take a while.
