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. Awarded the top performing Hydrangea arborescens for horticultural excellence and pollinator value by the Mt. Cuba Center Hydrangea Trial. 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.

HOW PLANTS ARE SHIPPED
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.
WHEN WE SHIP
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.

Excellent quality

C. Friedetzky from Maryland
I was wary of ordering plants that needed to be shipped. However, these hydrangeas' shipped rapidly, which is key to the condition they arrive in, were expertly packed, were in great condition and came with instructions.
When I planted them, they had a little bit of transplant shock, but on the same day.
Very happy with my purchase.

We ordered 4 Haas Hydrangea and got them last week. The plants were exceedingly well packed, with still-moist soil and in perfect condition. They are about 12-14" tall with healthy new growth. I set them out today and was happy to see nice, healthy roots. We couldn't be more pleased!

A puny specimen

A viewer from WV USA
I can’t believe you changed $38.00 for this puny plant. Although it was green, it was a thin single stem stuck in a gallon pot. It looked like a branch from a mature shrub that you propagated a couple of months ago. I have ordered many shrubs and hydrangeas through the mail in gallon sizes and have none have looked this immature and all were multi-stemmed. It would have been more honest to say you were out of stock then to send this. I hope it survives our winters here. Never again!

We are sorry to learn that this shrub looked unpromising on arrival. 'Haas Halo' is hard to find in the trade because it does not branch out and get full when grown in a container, but it certainly is splendid when planted out in the garden and given a chance to grow. Please rest assured that this plant has a robust root system and plant it as soon as possible so that those roots can get adjusted to the plant's new home. This plant is glorious in our gardens in northwest Connecticut and should do very well closer to its native range in West Virginia. We guarantee our shrubs for a full year and will be happy to refund the purchase if it does not perform.

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!

A viewer from New Hampshire
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!

Growing H. 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: In early spring, cut stems back by about one-third their total height, which builds a strong woody base. 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: Cut stems back by about one-third their total height, which builds a strong woody base while also encouraging abundant new growth for lots of flowers and a lush, full look. 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.
