One of the annual flowers I plant every year are zinnias. They are hardy and stand up well to the heat and dry conditions we seem to be having a lot of lately! Zinnias are so colorful and add some cheer to the yard. They are very easy to grow from seeds too. Another thing I love about zinnias is how they attract butterflies. There have been some little yellow butterflies hovering around them for a couple weeks but just today I noticed this black swallowtail out there. They usually come every year, and they're one of my favorite butterflies.
