I love azaleas because they come in my favorite color combo and all my towns are always set in spring and have a kawaii look to them so they really fit ^^
Hibiscus, I love the red and yellow colors. If only they weren't limited to summer. I'd love to see them in fall (the look would be so nice!) and spring as well. Azaleas and sweet olives come in a close second.
I like the hydrangeas dark green shrub all year long. I'm not a fan of the flowers on them for a couple of my towns.
I do like the azaleas flowers better but don't like the light color shrubs all year long.
