Have one I planted last year and just purchased 4 more, One of those has been planted, which may have been a mistake, as we have had no measurable rainfall in 2 months and am expecing draconian watering restrictions to be implemented any day by the local water dept.
They are macrophylla's and non-remontant (only blooms on last years growth). In your Zone, they would need winter protection to reliably produce blooms.
My yellow leaf macs, Lemon Daddy & Lemon Zest, did not suffer any foliage damage during the Easter weekend sub-freezing temperatures(25°F.) and apparently little or no flower bud damage, as they are beginning to bloom. Some of the nearby macs, with typical green leaves, were completely defoliated, are slow to recover and will not bloom this year. Big Daddy suffered some foliage damage, but is now covered in emerging blooms.
Since I am in Zone 7. this may not be very helpful to you, but if you can grow macs and get them to produce blooms, these will perform likewise.

Thank you, Rb! I would love to see some pics - would you care to share some with us please?

Thank you again!

P.S. Sometimes I do wish that I would be in zone 5 or 7 just so that I can have more plants to choose from! LOL

Consider yourself lucky to find these available. I have been looking for Lemon Daddy and haven't found them.. they are all sold out.

ostrich...
Wish I could share photos, but I only use a 35MM camera and slide film. We do a number of presentations each year and the available Digital projection device, PowerPoint, has a long way to go to equal the capabilities of slide projection. I have yet to see the remote control work on a PowerPoint and you must lug along a Laptop to control it. The cost is still very expensive, $900-$1000 for a device that still is lacking in quality, IMO.
Sorry!

Oooh, Rb, you are now teasing and torturing me.... LOL! Just kidding.... I understand, but if someone in your family has a digital camera, please ask them to take some snapshots.... I am dying to see that Lemon Daddy in bloom!!! Thanks!

Do the Big Boxes ever carry Lemon Daddy???

Lemon Daddy found and planted--anyone with experience with this hydrangea???
