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.

Geranium 'Johnson's Blue' is a classic hardy geranium known for its abundant sky-blue, saucer-shaped flowers that bloom from late spring to midsummer. Its finely cut, deep green foliage forms a dense, spreading mound that remains attractive throughout the growing season, turning red and gold in fall. This vigorous perennial thrives in full sun to part shade and adapts well to various soil conditions, showing drought tolerance once established. Resistant to deer and rabbits, it is ideal for borders, cottage gardens, and ground cover, providing reliable color and texture with minimal maintenance.

Planting: Plant in early to mid-spring. Soak roots in water for 3–6 hours before planting. Set the crown just below soil level, fully covering the roots. You can start them in pots or plant directly into the garden once soil is workable.
Location: Full sun to partial shade. Most hardy geraniums thrive in lightly shaded borders or open woodland settings.
Soil: Moist, well-drained soil with a neutral to slightly acidic pH (6.0–7.0). Enrich with compost or leaf mold.
Watering: Keep soil evenly moist during establishment. Once established, geraniums are drought-tolerant and need minimal watering.
Temperature: Hardy in USDA zones 4–8 (varies slightly by species). No winter protection needed.
Fertilization: Apply compost or a balanced fertilizer in spring. Avoid overfeeding—too much nitrogen can reduce flowering.
Pruning: Cut back after flowering to encourage fresh growth and possible rebloom. Trim to ground level in fall or early spring.
Propagation: Divide clumps every 3–5 years in spring or fall to rejuvenate and multiply.
Pest & Disease: Generally pest-free. Good air circulation helps prevent mildew.
