How to Grow Geranium Rozanne in a Window Box

Geranium Rozanne, commonly referred to as ‘cranesbill,’ is a versatile hardy perennial geranium that tolerates a variety of soil conditions, is drought resistant, and virtually pest free. She requires little care beyond regular watering, isn’t particular about sunlight or shade, demands little grooming, and still provides consistently vivid purple flowers for as long as the warm weather lasts.

Planting this hardy geranium in a window box is a variation on perennial container planting, which is a wonderful option for many reasons, including:

Planting in a window box offers the added benefit of Rozanne’s exceptionally vibrant flowers at eye level for her extended blooming season. Few perennials or annuals can boast the long flowering season that Geranium Rozanne offers. She comes on strong in the spring and continuously shows off her fragrant flowering abundance until the first hard frost of the winter.

To enjoy Rozanne in a window box follow these simple steps:

Step 1: fill your window box with soil

Rozanne isn’t exceptionally picky about the soil she lives in. She will grow best with good drainage, so choose a good multi-purpose potting soil or any other medium that isn’t clay-dense or otherwise overly water-retentive. Be sure that your window box has holes in the bottom to allow water to drain out.

Spacing each geranium about 12 inches/31 cm apart, place each root ball in the soil with the roots fanned down and out, and cover with soil. If your window box is very deep, you can plant multiple rows of Rozanne and allow the wandering tendrils to cascade over the edge of the window box.

Step 3: water your new cranesbill window box garden

After you have finished planting, give Rozanne a liberal watering to remove any air pockets around the roots. If some soil compacted or slipped through the bottom holes of the box, feel free to add some more to bring the level back up to normal again.

Now you are ready to enjoy this hardy perennial in your window box. Let Rozanne’s trailing greenstems and purple flowers brighten your spirits this spring!
