Product Details

The flower buds on this colorful Hydrangea paniculata Diamond Rouge® explode into 12–15″ panicles of flowers that open creamy white but gradually darken to pink before becoming a rich red in fall with the cooler night temperatures. These compact, award-winning plants have sturdy, reddish brown stems that make the blossoms ideal for cut flower arrangements. Showstopping in the mixed border or as a specimen planting. A First Editions® variety. 'Rendia' PP 24,667

Because Panicle Hydrangeas bloom on new growth, they typically flower normally even if the twigs have been killed back by frost. Plant in a sunny, well-drained spot; some early afternoon shade is beneficial in hot southern regions. Prune in late winter or early spring.

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.

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. We also ship a wide range of containers and planters, tools, supplies, fertilizers, garden wear, garden decor items, as well as indoor decorations like wreaths and dried bouquets when available. Estimated dates for shipping are indicated in the green Shipping Details box for each item. Please supply a street address for delivery. Kindly contact us with two weeks notice, if you'll be away at the 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.

Perfect Plant for Any Garden

These are the best hydrangea I have ever grown. We planted five of hem last June, and by July they were producing flowers nearly as long as the plants were tall. The flowers continue to grow while they bloom, until they are more than a foot long(!!). And over time their color changes, from white to pink and finally to red (which I've seen described as the strongest red of any hydrangea's). It's possible for one bush to feature all three colors simultaneously, and each flower really does last July through September. The plants themselves remain a manageable height, and relatively narrow for a hydrangea -- another plus. Each year, once in April and again in July, I give them a long-acting fertilizer, Plant-Tone -- but that's it: rake once in spring, fertilize twice, water as needed... Enjoy!

Slow to start but beautiful flowers this year

I ordered 3 bare root bushes last autumn and planted them right away when they arrived. They were very tiny when they came up late this spring. Each has grown branches at least 18 inches long and the one in a spot with morning shade has two gorgeous blossoms; the one in afternoon shade has a huge blossom but the leaves are discolored, whereas the leaves on the other two are a nice green so I don't think that's the sign of a healthy plant. The third one is planted in a spot with sun from 10 to 2. It only put out one branch this year which makes it look like it wants to be a tree. I may just wait to see what it does next spring...

Dead plants

When we got these, we ordered 2, one was already dead and the other one died within a week. My mom tried to baby them to get them to live but it was no use. They were so dried out and one had no leaves on it, the other minimal or brown, dead leaves. I would not reccommend you to anyone. It has been difficult to find a way to notify your company so I resorted to this review! I expect this to be honored and made right, when someone trusts you and you fail to deliver you lose business, you have lost ours unless you make this right.

Very hardy!

I live in rural Idaho so it usually takes a little longer for deliveries, so when my plant arrived last spring it was very dry and sad looking. After soaking in water it looked much better although a little rough around the edges. I did not get plant it right away as recommended and was worried when I did get it planted if I had waited to long. But it did grow and even got a few blooms on it which were beautiful. It came back this year and is growing just fine and looks great. Can't wait for it to bloom!

ordering a new one

My dear friend ordered one for her and one for me. Hers has done well while mine has pretty much died. When I planted it I noticed that there was not much for roots and I think that's why mine did poorly. I am ordering another because she was so proud to give this to me. She knows I love hydrangeas and have many in my yard.

Growing Hydrangea paniculata

Light/Watering: Most varieties thrive in full sun in the North, but in the South afternoon shade is required. 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. Avoid watering with overhead sprinklers to discourage fungal diseases.

Fertilizer/Soil & pH: Do not fertilize in the first growing season. Fertilizer is optional, once in spring with a fertilizer designed to encourage blooms (such as 15-30-15). An annual topdressing of compost is always beneficial. Soils should be moist but well drained, and rich in organic matter. Flower color is not affected by soil pH.

Pests/Diseases: None serious. Occasionally powdery mildew will infect the foliage, especially in humid areas with poor air circulation. Fungal leaf spots can occur, especially in fall when watered with overhead sprinklers, but they do not affect the overall health of the plant. Treat with Neem oil or horticultural oil, if the problem is serious, and be sure to rake up and destroy all fallen foliage in the autumn.

Pruning: Little pruning is needed, except to remove any dead or broken branches, and should be done only in winter and or early spring. Hydrangea paniculata blooms on new wood so avoid pruning in late spring and summer when flower buds are forming and getting ready to bloom. If desired, to rejuvenate an older plant, a third of the older and crossed branches can be cut back to encourage stronger branching with more numerous, although smaller, blossoms.

Tree form Hydrangea paniculata: Prune in late winter or 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.

Calendar of Care

Early Spring: If desired, prune as indicated above. Feed plants (optional) 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. Do not prune as doing so risks removing developing flower buds.

Summer: Do not prune in summer when flower buds form. Make sure to water well in dry weather and as flowers begin to develop. Lack of water at this time can cause blossoms to dry out prematurely and fail to develop color in varieties that display changing hues throughout the season.

Fall & End-of-Season Care: Remove and destroy any fallen foliage that could harbor disease spores. Cover the ground with up to 3" of mulch; avoid piling mulch against the trunk of the plant. Enjoy the dried flower heads through the winter, cut some to display indoors or deadhead them in late fall if you prefer, but do no substantial pruning.
