My mother always planted moss rose. Every summer, somewhere she planted some. They really are cool little plants. The leaves are fleshy with flowers doubled and showy. Typically they are in multiple colors. Occasionally they will self seed but most reliably perform as an annual. Looking at them makes me feel a bit nostalgic for my youth. Do you remember a plant from your youth? Something that reminds you of hot summer days that seemed to last forever?
Sometimes your flip flops just need a little bling. Something to make them a little fancy smancey. Something that says these aren't your ordinary foam shoes. So just take a little time and make your plastic fantastic! Tee hee!
