Product Details

A remarkable Lacecap, Hydrangea arborescens 'Haas' Halo' produces giant blossoms up to 14″ wide that are favorites of honey bees at our nursery. Held upright on sturdy stems, they provide easy access for pollinators. The flowers are handsomely displayed against leathery, blue-green foliage, and they will dry on the plant, remaining attractive for months. PP 24,783

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—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.

Planted in spring, bloomed by summer!

I ordered three Haas Halo hydrangeas for delivery this spring, and the plants arrived so healthy and green -- and also larger than I expected at over 12". I planted them according to the directions, and the plants shot up, despite the strange weather this year. All three bloomed beautifully by June, and we've been enjoying their beauty for weeks. I'm ordering all my flowering plants from White Flower Farm from now on!

Great plants

Kudos to WWF! I ordered 7 of these hard to find shrubs to start a hedge. The plants arrived in great shape. With other companies I’ve often been disappointed when the items arrive but not so with WWF. They were good sized, well branched plants , at least a foot tall. The plants were a little stressed when they arrived but I followed the instructions and they perked right up over the next 2 days.They are now in the ground and are looking quite happy. Thank you for a great job WWF!

Beautiful, Healthy Plant

I am so pleased with my Haas Halo Hydrangea. My plant arrived healthy and beautiful--about 18 inches tall-- in its special box. It was husky and well branched. Carefully packed and well watered with no loss of stems or leaves. It's in the ground now and looking very good. I have high hopes for enjoying this shrub for many years to come.

Beautiful Hydrangea

I am so pleased with this purchase. Just received my 'Haas' a few weeks ago, it was a tiny little thing but it has been off to the races since planting it in a mixed sun/shade border. Beautiful, big blue-green leaves and it's covered in buds. I'm excited to see it come into bloom its first year! And this one will make the pollinators very happy too.

I received the small, bare-roots plants in early April but because of late snows and heavy rain did not get them planted until May. I mixed a LOT of home-grown compost in the planting bed in a semi-shaded area. Now at the end of May (and above-average rains...(I have not watered since planting day) the plants are bushy, over two feet tall, and already forming flower heads. Holy moly! I didn't really expect any blooms at all this first summer. So far, way exceeding my expectations...I may have to buy more of this native hydrangea..

Growing H. anomala arborescens

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: Can be shortened, or pruned back to the ground, either in fall or early spring. Hydrangea arborescens blooms on new wood.

Reflowering: You may cut the first flowering stems of H. arborescens and hang to dry for arrangements; rebloom may then occur in August or September.

Transplanting: Young plants may be transplanted when dormant in early spring; larger tree-form varieties are difficult to move once established, but it can be done. 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: Prune as indicated above. Prune out any dead wood from all varieties. 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: Cut flowering stems from H. arborescens and hang to dry if desired.

Fall: Remove and destroy any fallen foliage that was infected by powdery mildew. If not pruned in spring, plants can be shortened, or pruned back to the ground.
