Gladioli are a diverse genus with around 300 species, often called 'sword lilies' due to their tall, slender spikes.
Hummingbirds are drawn to gladioli for their abundant nectar, a critical energy source for these high-metabolism birds.
The tubular shape of gladiolus flowers is ideally suited to the feeding habits of long-billed hummingbirds.
Gladiolus spikes provide flowers at a safe height, making them more attractive and visible to hummingbirds.
While red is a hummingbird favorite, it's the nectar quantity, not color, that's most important for attracting these birds.
Gladioli are easy to grow from corms and prefer well-drained soil and sunny spots, blooming in about 90 days.
