Plant success over seasons and recommendations

[Sgooosh]

Hi! after growing a few species of plants for a while now, I've noticed some things: (mostly Val gigantea and Rotala rotundiflora, also water lettuce)
During summer in my fish tank, these do very poorly, and just sit there and melt most of the time
during winter in my fish tank, they grow very fast and lush.
Outdoors, they do well almost all year round, growth is especially fast during spring.

My tank goes up to the 90s f in temperature during the summer, and the outdoors is almost constantly higher than that during the day.
The tank is 79 degrees in winter, outdoors is much colder, down to like 30.

Do you know if this plant growth difference is caused by temperature?
if so, what stem, or tall growing plants can tolerate these high temperatures?

Giant/ jungle Vallis and some species of Rotala, as well as Bacopa are cool water plants.

Water Lettuce is tropical but doesn't like high humidity caused by coverglass or enclosed hoods above the tank. It needs lots of air flow above it and good light.

Ambulia, Hygrophila polysperma, narrow and twisted Vallis do well in warm water and get to a reasonable height (twisted Vallis being the shortest out of them and reaches 12-18 inches high. The others can get to 3 or more feet long.

Amazon sword plants and Cryptocorynes like warm water. Some species of sword plant can get huge while the Crypts tend to remain small.
