π± Gladiolus are not a shade garden flower, and here is why that matters.
Gladiolus need at least six to eight hours of direct sun to develop strong, upright stems and fully open blooms. In too much shade, stems tend to stretch, weaken, and flop over before the flowers even open.
If your only available spot gets partial shade, you can still grow gladiolus there, just expect shorter stems and be ready to stake them for extra support once buds start to form.
