Hello, me and my fiance are thinking of planting some flowers in the homemade flower pots imaged here we made from an old fence. We are going for a rustic look that will be held in the Colorado mountains. My question is what would you recommend to plant this late in the season in hopes to have blooming flowers on Sept 21st (wedding date)? Just thinking big lush and beautiful if possible. I live in Denver and would put the pots in full sun and water every day until this date. Thanks!
