Remember that QF can get to really Big

Your picture is really awesome! It's unlikely they will get too big in my climate. If it does, it will be years. I can always prune it too.

Don't worry about any of them surviving, they are tough enough to generally laugh off my long COLD winters! And, yes, 'Quick Fire' does get big, maybe even up to 7 ft or so here!

Where is "here" FrozeBudd_z4? For some reason our climate has a tendency to be unfriendly to hydrangeas, even panicles. It's something about our elevation, dry climate, harsh winds and winters. i have seen quite a few more panicles here but never any 7' tall. But maybe I'll be the first!

Popmamam, FrozeBudd is in Alberta. My Quickfire is big also, so I don’t think yours will be much smaller than 6-8 feet tall and wide.

Somehow I don't think it will get that big but if it does it will be years! Hydrangeas just don't seem to get that big here. But we shall see.

Thanks for the info, FrozeBudd. I read about Moonrock online ("cousin" of Limelight... or Little Lime to be more proper) and have been waiting for someone to comment. Good to know that it is working out well for you and that you recommend it!

Luis, yes, 'Little Lime' has really good bloom substance and I see that reflected in 'Moonrock', thus more resilience to drying and burning. I'm in the far north and what also sets 'Moonrock' apart from either 'Limelight' or 'Little Lime' is its early flowering ability, weeks ahead of them and the plant also displaying superior winter hardiness. Some of these attributes not being a factor for longer milder growing regions, though bloom substance is important no matter where one lives. 'Little Lamb' is near perfect for my conditions, though again lacks a bit when it comes to substance.

Popmama, in my garden, QF went from about a foot tall to over my head in 4 growing seasons, the fastest plant to size up in my garden ever. It would be far easier to move your Quickfire sooner rather than later, and IME they aren’t easily controlled as to size by pruning since a hard spring pruning will regrow to almost the same size in one season. They honestly aren’t small plants, even in cold and relatively dry areas like Colorado and Alberta.

As it currently stands, I think that the QF may start swallowing the plant next to it in the photo within a couple of years.

Fortunately there is nothing next to Quick Fire. The dwarf Alberta spruce in the background is further away than it appears in that picture. There is nothing on three sides of the Quick Fire at all.

The discussion did spark some curiosity about average humidity. Just for fun, I looked up the average humidity in Edmonton to compare to Denver. Edmonton's average humidity is 54%. Denver is 37%.

Obviously there are many factors so all I can do is wait to see what happens. I will say that I have not seen anyone around here growing Quick Fire, so I have no real comparison. I will keep you all updated!

Thank you for the information about Moonrock as well. I have never seen that variety here, but I will be looking for it!

Denver Botanic Gardens says online that they have a couple of the older types of Hydrangea paniculata, Pink Diamond and PeeGee.

I see quite a few Limelights around now and more and more Pinky Winkys. Haven't seen any Quick Fires but I keep looking! I'm the type of person who will literally stop in front of someone's house to carefully observe their garden if something strikes me. I am guessing that I will start seeing more of the Quick Fires soon as they have definitely been selling them at the local garden centers.

Fire Light is another great Hydrangea https://www.google.com/search?source=hp&ei=AWt6XbHIEZCPlwSt4pvgBg&q=firelight+hydrangea&oq=fire&gs_l=mobile-gws-wiz-hp.1.2.41l2j41i67j0l2j46j0l4j0i131.2627.5219..7910...0.0..0.213.651.0j3j1......0....1.......8..41i275j41i299j41i160j46i131.kL0fkHMWZ8A

Thanks, hyed. I have seen Firelight on the PW website. I've never seen one for sale here. The season is pretty much over here. Garden centers are completely emptied out of hydrangeas. I think I bought them all (haha). I don't have any room for anymore in my yard for now but my mom does! So next year maybe I'll get her a Firelight. She has Limelight and Pinky Winky from last year. Limelight did much better for her than Pinky Winky. This year, I bought her another Pinky Winky to try in a different location, a Quick Fire, and I found one Zinfin Doll for her as well.

Here is a PW about 20yrs old pruned to tree form

I think you don’t see as many QF around because it seems most folks prefer the really large full blooms. QF is lacy, but the quality and length of bloom more than makes up for the less dense flower heads. It is one of my absolute favorite plants that I cannot imagine a garden not having.
