Geometry Nodes Flower Grow - How can I bloom the flowers via animated vertex weights or vertex groups

Since Blender's Geometry Nodes doesn't have loops for now, you cannot make a flower 100 times in a row. Also, you cannot modify the flower after it was instanced, because it will be very tricky in ...

Geometry Nodes Flower Grow - How can I bloom the flowers via animated vertex weights or vertex groups

It seems from your .blend, you are using only the DP weight for animation. Given that, you could consider the growth of the flower as a whole, including stem-extension and petal-rotation, as a single ...

How to "Distribute Points on volume" in Blender but not randomize them

Well, silly problem, all the nodes are more or less correct, except (as mentioned in the comment) You need to connect the attribute to the vector of the Align Euler to Vector, not to the rotation.
