I am a landscape designer and have been purchasing 1000's of spring flowering bulbs from A.D.R. Bulbs for 100's of clients in the last 20 years. The bulbs have always been of top quality and if there were any problems, they have been quick to rectify. My orders are often complicated with many varieties and different amounts and they have always filled and delivered everything on time with the best customer care and attention to detail. The pictures in their catalog and website are beautiful. I have visited their facility in NY and was impressed with all their handling equipment and organization. I would highly recommend A.D.R. Bulbs to anyone in the wholesale trade who wants to purchase quality bulbs and work with genuinely nice people.

Growing and Maintenance Tips for Gladiolus Large Flowering 'Priscilla' (Ships in Spring)
Planting: Plant corms in spring after the last frost, 4 to 6 inches deep and 6 inches apart, with the pointed end facing up. For continuous blooms, stagger plantings every 10–14 days until midsummer.
Location: Full sun is best. Choose a sheltered spot to protect tall flower spikes from wind.
Soil: Well-drained, sandy or loamy soil with a slightly acidic to neutral pH (6.0–7.0). Add compost or grit to improve drainage.
Watering: Water deeply after planting, then weekly during active growth. Mulch helps retain moisture and suppress weeds.
Temperature: Hardy in USDA zones 8–10. In colder zones, lift corms in fall and store in a cool, dry place.
Fertilization: Apply a balanced fertilizer (e.g., 5-10-10) at planting, then every 4–6 weeks during the growing season.
Pruning: Remove spent flower spikes to encourage more blooms. Allow foliage to die back naturally to feed the corm.
Staking: Tall varieties benefit from staking to prevent flopping. Insert supports early to avoid damaging roots.
Propagation: Lift and divide corms in fall. Replant healthy corms and save offsets for future seasons.
Pest & Disease: Watch for thrips, aphids, and fungal issues. Rotate planting sites and ensure good air circulation.
