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.

Paeonia 'Sunny Girl' (Ships in Spring)

Garden Peony

Introduced in 1985 by American breeder Klehm, Paeonia ‘Sunny Girl’ is a standout early‑season peony known for its bright, cheerful yellow semi‑double blooms. Flowers open in late spring with broad, buttery‑yellow petals surrounding a warm golden center, creating a luminous, sunlit effect that holds beautifully in the garden. The blooms are large, lightly ruffled, and carried on strong stems that rise above a full, rounded clump of deep green foliage. While not an APS Gold Medal winner, ‘Sunny Girl’ is widely appreciated for its reliable performance, vibrant color, and strong retail appeal in the increasingly popular yellow peony category. Thriving in full sun with fertile, well‑drained soil, it is a long‑lived, high‑impact variety that brings early brightness and exceptional garden presence.

Growing and Maintenance Tips for Paeonia 'Sunny Girl' (Ships in Spring)

Planting: Plant as early in spring as the soil can be worked—ideally before daytime temperatures consistently exceed 70°F. Set the crown 1 to 2 inches below the soil surface. Avoid planting too deep, as this can delay or prevent blooming.
Spacing: Space plants 2.5 to 3 feet apart to allow for mature spread and good air circulation.
Light: Full sun (6–8 hours daily) is best. In warmer zones, light afternoon shade can help reduce heat stress.
Soil: Rich, well-drained soil with a neutral pH (6.5–7.0). Amend with compost and grit if needed to improve drainage.
Watering: Water deeply after planting and keep soil evenly moist (not soggy) through the first growing season.
Temperature & Humidity: Hardy in USDA zones 3–8. Spring-planted peonies may take longer to establish and bloom, especially in warmer zones.
Fertilization: Hold off on fertilizing until the second year. Focus on root development in year one.
Staking: Large double blooms may need support. Install peony rings or discreet stakes early in the season.
Pruning: Deadhead spent blooms. Cut foliage to the ground in fall after frost.
Propagation: Divide clumps only if necessary, and only in fall—peonies dislike disturbance.
Pest & Disease: Generally pest-free. Good air circulation helps prevent botrytis blight. Avoid overhead watering.
