Gladiolus ‘Red’

Gladiolus are often grown for elegant flower arrangements, but they are also an excellent choice to fill your garden with beautiful colors!  Their sword-like foliage and tall, impressive flower spikes make striking accents to the mixed flower border.  They are also key elements in a shrub border and amongst perennials.  Gladiolus are among the best flowers for arrangements, lasting a week or more in the vase.  These stately flower spikes are also called sword lilies.  This garden favorite is available in a rainbow of colors, and their long stems allow you to grow armloads of flowers in a small space.

Gladioli have been extensively hybridized to offer an incredible array of colors.  Plant in groups of six or more of a single color for the best garden effect, or grow dozens of them in a bed reserved for cutting.  Imagine the luxury of having armloads of glads to display around the house!

Planting/Care Instructions +

Planting Instructions: Plant in the spring, after the ground, warms to about 50º F. Two weeks before the last frost of the spring, plant in a sunny location in well-drained or sandy loam soil. Gladiolus will grow in any good garden soil but do need full sun and good drainage. Space plants 5” apart. 1. Dig a hole 4-6" deep. 2. Place corm in a hole pointed side up. 3. Cover with soil and water thoroughly. For continuous summer color, plant at biweekly intervals. Stake for best appearance and straightest stems. Remove faded/dead flowers to ensure continuous blooms. Increase water and fertilizer when flowers begin to develop. In zones 7 or lower, lift corms from the ground after the first frost. Allow the corms 1-2 days to dry and gently brush off excess soil. Store them in a cool, dry place during the winter months. Moisture: Water as needed to keep the soil moist. Mulching around your gladioli can assist with keeping the soil moist and preventing weeds.
