We will both learn something through this experience.
This jutsu creates flowers and hardens them to the level of regular shuriken before launching them at the target. I would use this jutsu as a distraction or a way to overwhelm the opponent. I would combo it with the Shuriken Shadow Clone Jutsu to increase effectiveness.
This jutsu is does the same thing as the jutsu listed before except that the flowers surround(assumingly) the user. It could be combo'd with Taijutsu and also used as a deterrent to Taijutsu.
This jutsu creates a meadow of flowers around the target which are then used as a medium for fire to travel at the target. Based on the anime, the fire comes from multiple angles along the meadow. I would combo this with a jutsu that strikes from above. The jutsu can be jumped above using a basic Doton so an attack from above would be an ideal combo.
The jutsu specifically creates sakura petals in which allow the user to blend in with. I would combo this with a genjutsu or clone jutsu. The masking of the clone could also allow me to hide while the clone fights or mask another offensive attack.
In the anime the flowers drop from above and explode. This could be combo'd with Hana Ninpou: Hyakkaryouran. The fire could force the target to jump into falling exploding flowers. Together they would limit the escape routes.
