We all know the holidays in which flowers are the only acceptable form of gift. While these days are special and we can feel good about greeting our loved ones with a bouquet of beautiful flowers as a small token of our appreciation for everything they do, there are other unique occasions that hardly anyone thinks to celebrate the same way. Here are five out-of-the-box flower-worthy occasions coming up next month where a bouquet of flowers would certainly brighten up a family member or friend’s day.

National Courtesy Month

September is National Courtesy Month! It’s OK, we had no idea, either, but we can all use September as a way to help convince the pessimists of the world that common courtesy is indeed alive and well. We’re sure we can all agree that giving one of your favorite people a beautiful bouquet of flowers would certainly be seen as a courteous act.

Self Improvement Month

September is also Self Improvement Month. If a friend or family member has been wanting to make a positive change in their lives, or mentioned trying something new that they haven’t gotten around to doing yet, give them a little token of encouragement to get started.

Grandparent’s Day

Grandparent’s Day falls on the first Sunday after Labor Day, making this year’s Grandparent’s Day September 13. If you don’t visit your grandparents often enough, pick up a bouquet of flowers and drop by for a visit on this day — they’ve earned it.

National Women’s Friendship Day

Our female friends play such important roles in our lives, hopefully throughout the course of years. Do something special for your closest friends on September 20 to celebrate National Women’s Friendship Day. Maybe host an intimate dinner at home or go out to your favorite meeting spot — whatever you do, choosing a small bouquet for each of your girlfriends to show them how much you appreciate them being a rock for you when you’ve needed them will definitely be appreciated.

World Gratitude Day

September 21 is World Gratitude Day. Originated in Hawaii and celebrated since 1966, this is a day where flowers from Sydney could have a positive impact on someone day. World Gratitude Day centers around the notion that we are happier people when we take the time reflect on the amazing things we are privileged enough to have in our lives. Share your appreciation for all that is good in your life on World Gratitude Day with a bouquet for someone who has consistently made your life better.
