For the most blooms, plant balloon flowers in locations with part to full sun with adequate drainage, says Gene McGinnis, author of Bird-friendly gardening: Tips and projects for supporting birds in your landscape. “I grow pink balloon roses in my front garden in soil that drains quickly after rain. They are planted with bearded irises and daylilies in a part-sun location.

A little afternoon shade can help the plant tolerate hot summer weather.

In cold areas, the plant dies back to the ground in winter. They are often one of the late perennials that emerge in the spring, so you may want to mark the spot in some way so as not to overplant them. And choose that spot wisely – balloon roses don’t like to be transplanted or divided because of their long taproot.

“The plant is slow to emerge in the spring, so make sure you don’t accidentally remove it when the garden season starts. It does best in a place where it won’t be moved. It’s been mine for several years! says Jane.

If you want to save the seeds, wait until the pods turn brown and dry completely, then open them in a paper bag. Sow the seeds directly into your garden the following spring.
