Hydrangea paniculatas are very winter hardy, can withstand full sun and bloom reliably in your Zone. Just select them based on lacy blooms and the plant dimensions. Example: Bobo, Tiny Quickfire, etc etc.

Hydrangea arborescens are very winter hardy, bloom reliably and prefer morning sun only. You can choose compact, lacecap cultivars like Invincibelle Lace, etc etc.

Finally, reblooming macrophyllas that are not tall can be an option. They can be less bloom reliable in your zone than paniculatas and prefer morning sun only. Choose cultivars that are not tall, like the Let's Dance Series Starlight and Can Do.

Any particular cultivars you've noticed that bring the pollinators to your yard? I'm having a hard time finding a good resource online as it will be difficult to find 100% native species for my plant list.

Bees tend to be not very attracted by hydrangeas. That's because most of the most popular varieties have been bred to focus on the larger and showy sterile florets. Since the sterile florets produce no pollen or nectar, they offer no appeal to bees.

If you want to draw bees to your hydrangeas, you will need to focus on those varieties that provide abundant (but tiny) fertile florets. Lacecap macs and H. aspera tend to be the biggest draws because of the quantity of fertile florets offered. I would avoid any mopheads and issues with climate hardiness and sun exposure would point me towards the very loose paniculatas, like Tardiva, Brussels Lace, Kyushu, Chantilly Lace, Dharuma, as these offer a more balanced mix of sterile and fertile florets.

Same with any arborescens. Avoid the rounded, dense domes (like Annabelle or Icrediball) and focus on the more open flowers of the species or a lacecap form like Haas Halo. Not quite as sun tolerant as the paniculatas, though.

Climbing hydrangea would be a good choice as well.

Thank you! This is a good list to stsrt. a few of my local nurseries keep plant lists so it will help me to weed some out and narrow them down. Fortunately I’ll be nale to drip these new plants, though not a true solution to afternoon sun.

That is a great find! One of my nurseries had a number of the Invincibelle cultivars listed and I was wondering if they'd be an option. The don't appear to have fared well at all with bees. Thank you!
