Sale Hydrangea Haas Halo bush

Hydrangea arborescens 'Haas Halo' (smooth hydrangea)

Next available Monday or Tuesday

Unavailable Available Only few left Out of Stock Pre-order

We simply had to get one of these Haas Halos smooth hydrangeas for our garden. Those plate-sized lacecaps couldn't be resisted. 

Planted out in the garden, we were impressed with its heat tolerance and resistance to wilting during dry, baking summer days.

The fat stems are a big deal to us - they easily hold aloft the 6-8" diameter, pollinator-magnet lacecaps.

Oh, you love bees and pollinating insects? These giant lacecap heads have centers packed with fertile flowers that will attract your insect friends to your garden.

This is another smooth hydrangea that makes a lovely cut fresh or dried flower head.

More will be available late summer 2020. ūüĆĪ

Grower's Note: We grow smooth hydrangeas in RootMaker pots so we induce the best, well-branched, non-circling roots possible. These pots are expensive, so we take your plant out of the pot, then we clean and reuse the pot (recycling!). To ship your plants, we carefully wrap the roots in a compostable plastic bag, then put them in a paper bag; then they are boxed. This triple packaging holds together very tightly during shipment. Please have a pot on hand to shift them up into, but they will hold as-is in the packaging we send them for several days before planting (please water them!). The goal of this system is to have good roots and reduce trash.

To Make It Thrive
Give 'Haas Halo' smooth hydrangea rich soil plus consistent moisture in a soil that drains. It may require extra watering, but no standing water. Smooth hydrangeas loves a layer of compost, then a layer of mulch on top - both to provide a rich and cool root zone. Place it in full shade or afternoon shade in the deep south (zones 8 and 9), but full sun is okay farther north. Best flowering is with some sun.
Plant Patent
Is this a pollinator plant?
Yes! This smooth hydrangea is a lacecap so it has a cener of fertile florets that really attract the pollinators.
