Notes
'Costa' gladiolus (Gladiolus 'Costa') is a bulb for borders, cut flowers, and containers. It is hardy to USDA zone 8, or down to 10°F (-12°C). This plant likes full or part sun and average to wet, sandy, loamy, or chalky soil. The fragrant flowers attract butterflies, hummingbirds, and bees. Plants grow about 35 to 47 inches tall, so you can cut the spikes for bouquets.
