Understanding Plant Options
Nature Hills offers plants in two main formats:
- Container Plants: Grown in pots with soil, sized by container volume and plant age
- Bare Root Plants: Dormant plants without soil, sized by height measurements
Container Plant Sizes

Your Very Whimsical Sentimental Blue Balloon Flower
- Amazing True-Blue Balloon Shaped Flowers
- Easy To Grow and Care for
- Low Maintenance Plant
- Green-Grey Foliage
Sentimental Blue Balloon Flower (Platycodon grandiflorus 'Sentimental Blue') is one of the most unique plants that you will ever grow in your garden.
Even though it is a classic garden plant in Europe, it isn't often seen in American gardens, which is a shame. Help us trumpet the joys of this great garden flower by planting some at your home this year!
Sentimental Blue Balloon Flower has some of the most interesting flower buds ever and typically bloom from May to August.
They look for all the world like little blue hot-air balloons and they swell and swell until they burst open into beautiful true-blue flowers with purplish veining. Kids are enthralled by them.
Sentimental Blue is perfect in the front of the perennial border or lining a walkway. They make great accents in rock gardens and are star performers in containers.
Grey-green leaves back the long-lasting flowers which give them quite the 'designer look', which are perfect for cutting too.
Sentimental Blue is very low-maintenance once it's established, but note that it emerges late in the spring so care must be taken not to damage the crowns with early spring cultivation. With very little care this beauty will reward you with years of garden whimsy!
Order your very own Sentimental Blue Balloon Flower today from Nature Hills! It's a fan favorite, so the sooner you order the better!
