Logs and filler were from a pine we cut down, pampas grass and various fallen branches, and lots of trimmed wisteria. There's a paper bark birch just off camera on the right along with a crepe myrtle.
The flowers are from on of those seed blankets. I didn't have time this year to cultivate perrenials so went with an easy colorful first year.
Eventually expanding this little garden to turn that side yard into a miniature native plant meadow.
