Balloon bud in the lower left |
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 |
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?
