What are the main differences between Rocket and Dynamite Crepe Myrtles?

Question

Does one produce redder blooms?

Which has a longer bloom period?

How tall does each one get?

Are the blooms larger on one than the other?

Answer 1

to me red rocket and dynamite look the exact same height leaves and blooms.

Answer 2

my Dynamites get great dark maroon new growth... burgundy buds, really red flowers, sometimes with white picotee edges if our weather is cloudy.......

this site compares them....

only difference I see is that Rocket will do a second bloom easier than the other....but mine does a second bloom just fine.... of course, our summer is long and fall is warm, too.... so it has longer to do the growing.... personally, I can't tell a difference other than  on this site, it's pictures, I see more of a red color on  the leaves onRocket, and not on the other...which might affect what color it is in fall.....
