| Balloon bud in the lower left |
A friend offered a share of a balloon flower plant from her front garden. The balloon flower did not excite me much, but I needed filler material for the recently-created, clay-packed side yard garden along new platform steps to the back yard and deck.
Five years have passed, and the plant is finally beginning to spread a little. This year it sent up a short, second stalk. And, the flowers are more numerous, forming small clusters. The rude rudbeckia and brute baptisia have invaded the side yard garden, and are elbowing out the balloon flower and a few others that make this garden home.
Platycodon gradiflorus is a perennial, native to eastern Asia and Japan, and generally grows in climate zones 3-8 in the U.S. Flower buds resemble balloons, or paper lanterns if you are in Japan. It likes full sun and tolerates partial shade, where you will find mine. Cultivars are available in white and pink, and in dwarf sizes.

| Context |
Several sources state that because of its root system, it does not take kindly to being moved. If it is transplanted, it takes a year or two to recover. This is probably why my plant begin its first few years in its new home with only a few blossoms no larger than a quarter.
It is most likely stepped on when doing spring gardening chores, since it leisurely emerges after winter and is located in a perfect spot for a foot to balance on. I would like to move it, but after learning about the transplanting issues, may try to improve it in situ. I like it, but I need several more to form a clump to give it some presence among its neighbors.
The blue flowers are over 2 inches inches across (5 cm) and plants
can grow up to 3-feet in height (1m). This five-year old is (maybe) 24-inches (60 cm). My friend's plant tends to take a bow, but in my garden it stays upright, probably depending on the surround rudbeckia and iris to maintain its posture.
Other facts surprised me. It supposed to rebloom if deadheaded, so I need to give this a try. Taller plants should be staked, and cutting stems back in May could help keep the plant shorter and therefore upright. They make good cut flowers, but with only one lonely stalk here, cutting would eliminate the plant in the garden! They are not invasive -- did you hear that rudbeckia?

Datura arrayed along the entry to the house where I enjoy the intoxicating fragrance every summer evening. They reseed themselves every year.
Rudbeckia hita native loves the sun. They last about two years, but easily reseed.
Rudbeckia laciniata picked up at a plant swap, it grows 6 feet (2 m) tall and easily falls over. Thanks to Janet, Queen of Seaford in identifying for me.
I thought a closeup of the balloon flower would be interesting. Platycodon grandiflorus reseeds but they're difficult to move because of their deep tap root.
Phlox paniculata 'Jeana' giveaway at the Washington DC Garden Bloggers Fling. Pollinators love it as much as I do.
When echinacea purpurea is planted in part shade, it gows 5 feet tall (1.5 m).
Echinops ritro is about ready to bloom and inviting all the bumbles to it.
