Many newly planted trees don't showcase their true potential for fall color (or flowers, or any number of other physical characteristics) until they're fully established, which can take a full year (or longer) from planting.

Even though you mentioned the taproot being intact, Nyssa is often known to "sulk" and suffer from transplant stress after planting, an issue which can be magnified with larger caliper specimens like yours.

As long as the trees are well watered and mulched, I wouldn't give too much thought to them not performing as "advertised" until they're established. I expect that next fall, you'll probably get a much nicer foliage show.

ive had some trees take 5 to 10 years.. to finally show the color they were supposed to.. its mart of becoming fully established.. and performing to expectation ..

and stress can upset the process.. and obviously.. digging moving and planting is a lot of stress ...

tree time is counted in decades [do many of you wait for that comment.. lol ...]... so taking a few years to get fully established shouldnt be surprising ...

Thank you both

Oops I did not get a close up of my wildfire. Its down there 3rd to te streer side of the Metasequoia on the left.

Its roughly looking like it does during the spring.

The Wildfires we've planted here tend to hold their leaves late and hard freezes usually hit them before fall color has had a chance to develop. I drove past one of our Wildfires today, and the foliage was still green (and slightly chlorotic). They also typically show some tip dieback after colder winters. Not a variety I'd recommend for colder zones, but I assume they probably perform well and color up nicely in milder areas.
