Among the most striking of the flowers that bloom from bulbs, gladiolus are best known and most often grown for cut flowers. Our bulbs are of fine quality, #1 size for the tall standard varieties and top size for the border gladiolus. You will find that these larger bulb sizes produce stronger plants and larger flowers than the so-called ‘landscape’ (smaller) bulb sizes often offered in the trade.

Planting Gladiolus corms outdoors in late spring: Although you may plant gladiolus corms directly into the soil, you may wish to consider a simple, yet effective fungicidal treatment prior to planting: Fill a 2 gallon bucket with water and add 1 cup of household bleach. Place the gladiolus corms in the water, soaking them for about 15 min. to 1⁄2 hour. Remove and let dry naturally. Plant normally.

Your gladiolus corms will be shipped to you directly from our grower via UPS (Sorry, we cannot ship to Alaska, Hawaii or Puerto Rico), ready to plant in the field, or sell directly to your customers. We will begin shipping to your state according to the schedule below. You may also request to have them shipped any week after the first ship week for your state. (If so, you must indicate your requested ship week.) Please note that our grower may delay shipment due to weather conditions. Planting instructions will be included with your shipment.

The products listed in this section start shipping either February or March depending on the item and/or your location. See individual product pages for more information and any state restrictions.
