Support Tall Varieties if Needed
Some cornflower varieties—especially heirlooms and taller selections—can reach up to 3 feet tall. In windy or exposed gardens, those stems may need a little support to keep them from flopping. Once they start leaning, it’s harder to fix!
I use simple twine between wooden stakes to create a low grid, or you can try lightweight garden netting. Supporting early ensures the plants grow upright and evenly spaced. Not only does this keep the display looking tidy, but it also makes it easier for bees and butterflies to navigate the patch without getting caught in a tangle of bent stems.
