Thinkin about this lil lady and her fighting style.
As a child, it's a bit more evasion focused, with heavier influences in ballet and basic gymnastics. Jumping, dodging, balancing, flipping, she's not meant for up-close combat like this. Her smaller stature lends more to her speed and ability to maneuver more freely, making her harder to capture.
With her DF, she is able to create things like vines and flowers, using them to further enhance her reach and distance. Using the vines like a whip-like appendage, she can grab things, swing from high places and pull herself out of tight spaces and situations. With the flowers, she can make large ones that function similar to bounce pads or trampolines, allowing her to bounce around and bound to higher places or over thinggs easier. They manifest like lily pads, and disappear when she wills them to. She can also create a protective cocoon of vines and/or tree bark as a shield.
In terms of attacks, she has very few as a child, being very defense and support oriented. She can combine her vines with something heavy on the end, like a rock or weapon, and use it similarly to a chain whip/rope dart. Her movements with them are often mixed with her ballet and gymnastic abilites, making for very quick, precise attacks, though not the strongest thing in the world, especially at her weaker power level.
She can try to upgrade and adapt attacks like this by using her vines like areial silks and bringing momentum into the mix, similar to this. Attaching something heavy to the end of a vine and spinning like that to gain momentum could really pack a punch.
As an adult, her fighting style does evolve. She is far more skilled in hand to hand combat, leaning much heavier into kickboking and more advanced gymnastics more than ballet, though some elements still remain. By this point she has become much stronger, physic much like this, although a bit bigger for her stature (6'2).
A lot of her strength is in her legs, her kicks bordering on deadly with enough force (similar to Mirko from MHA.) But that doesn't mean she doesn't know how to punch either. This strength also lends to her speed, and stamina, allowing her to jump higher and move much faster simply running.
Her attack now can range from close combat to ranged, and she can rapidly switch between the two. Her use of plants and vines have shaprened over time, her aim far more precise and even capable of constricting the movement of her opponents.
With her extended knowledge on different plants and their knowledge, she can also create different concotions for both healing and harming others, and sometimes just grow the plant itself (i.e poison ivy). She is far more head on with her opponents, far less shy and evasive than her younger counterpart. She is not afraid to get as close as possible to someone to go in for an attack.
Obviously, her weakness comes from not only the sea, but also fire, as well as surfaces that can't facilitate life like metal. It would force her to grow things from herself, which can be dangerous and very draining very fast.
