Product Details

Product Details

The so-called PeeGee Hydrangea, well loved by generations of gardeners and for good reason: in late summer it produces huge, conical trusses—up to 18″ long—of double flowers that are rich creamy white and fade gradually to pink and then brown. It forms a broad shrub to 10′ high. Flowers appear on new growth, so late winter or early spring is the best time to prune the overall shape or to remove any stems damaged during the winter.

Hydrangea is a valuable genus of some 100 species of shrubs and vines grown for their large and very showy flower heads. Hydrangeas are at their best in summer and fall—a quiet time for most woody plants—and are worth having for that reason alone. For more information on Hydrangea care, click Growing Guide.




The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.


We ship our bulbs and plants at the right time for planting in your area, except as noted, with orders dispatched on a first-come, first-served basis by climate zone. Estimated dates for shipping are indicated in the Shipping Details box for each item. Please refer to the Shipping Details box to determine the earliest shipping time. Unless you specify otherwise, fertilizers, tools, and other non-plant items are shipped with your plants or bulbs. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at expected time of delivery.


We guarantee to ship plants that are in prime condition for growing. If your order is damaged or fails to meet your expectations, we will cheerfully replace or refund it. Please contact our Customer Service Department at 1-800-503-9624 or email us at [email protected]. Please include your order number or customer number when contacting us.

Very disappointed

Double Deuce from Westchester, New York

When I received this it came in good shape and while I was disappoyinted with the size of the tree, the shape and root system were very good. That said I planted it in a new bed with well cultivated soil in full sun about 4 years ago and it has barely grown at all. It is just over 4 feet tall and while the trunk of the tree has grown slightly in diameter and the canopy of the tree has become about 30 inches in diameter, the branch are wispy growth and the flowers are smaller than the size of an orange with most being tangerine in size. I know qthe gardeners rule of the first year it sleep, the second year it creeps and the third year it leaps, well I'm heading into the firth season of it being in the ground and I haven't had any leaps so far, so at the rate it's growing it will be a very long time if ever that this tree becomes close to it mature size indicated on the website. I can't see how this becomes a tree like in the pictures on the website or that this will ever produce panicles up to 18 inches long as the site indicates in the next 5 years. Overall I am very disappointed with this selection because I planted it in a prime location and don't feel that it will ever achieve my desired goals for this bed. If I had planted it incorrectly or located it in a less than optimal growing conditions then I could accept blame for it disappointing me but that's just not the case, so based on my experience I cannot recommend this to anyone.

Growing H. paniculata

Light/Watering: Most varieties thrive in full sun in the North, but in the South require afternoon shade. Moist soils that do not dry out are best; do not plant in hot, dry, exposed sites. Mulch to conserve moisture and buffer soil temperatures.

Fertilizer/Soil and pH: Fertilize once in spring with a fertilizer designed to encourage blooms (such as 15-30-15). Soils should be moist but well drained, and rich in organic matter.

Pests/Diseases: None serious. Occasionally powdery mildew will infect the foliage, especially in humid areas with poor air circulation. Treat with an appropriate fungicide if the problem is serious, and be sure to rake up and destroy all fallen foliage in the autumn.

Pruning: Little pruning is needed beyond removing any dead wood whenever seen. If desired, plants can be cut back as needed in early spring. Hydrangea paniculata blooms on new wood.

Tree form Hydrangea paniculata: Prune in early spring, removing lower suckers and up to half the older top growth.

Transplanting: Young plants may be transplanted when dormant in early spring. Prune top growth after transplanting to reduce water loss.

End of Season Care: Rake up and destroy any fallen foliage that was infected by powdery mildew or other fungi.

Calendar of Care

Early Spring: If desired, prune as indicated above. Feed plants with a fertilizer high in phosphorus (such as 15-30-15) to encourage blooms. Complete any transplanting before leaves unfurl.

Mid-Spring: Mulch plants after soil has warmed to conserve moisture and buffer soil temperatures. Watch for powdery mildew and treat as needed.

Summer: As soon as blooms fade, remove old flowering stems.

Fall: Remove and destroy any fallen foliage that was infected by powdery mildew.
