This is really creative and challenging! It took me a minute to understand how the plants worked, but as soon as I got it down I started flying through the levels. I enjoyed playing this a lot!
A bug that I found though, I tried to make it to the portal a couple times on the level where you place thorns across the floor and climb over the topside with flowers, but I'd constantly hit the ceiling and get knocked into the small crack right at the end and start infinitely falling.
