No- it’s not the rain barrels ( but I have collected .5 inch of water!) but look how beautiful my garden is doing this year!!!
I love the addition of the Sunflowers- this will now be a yearly plantings because they are so big and beautiful. BTW- the rain barrels can’t be painted- they need to be black for some reason 
( I had asked) . I also don’t have a rain spout to collect more water- I just need to keep moving the barrels around till I find the exact spot where I can collect the most water. There are butterflies and dragon flies all over the garden but so far no luck with any hummingbirds… 
Wow, your garden looks great. I guess the rain helped a lot!
You should plant some agapanthus (Lily of the Nile). They attract hummingbirds like crazy!! They will get bigger with each passing year and are beautiful.
It's beautiful! I want a butterfly bush like yours for the front yard at The Breeze Inn.
