The flower leans and keeps the posture, where you find the beauty with strongness and ephemerality. 

It has a different charm from the flower that extends lengthwise.

Also, the impression people get will change depending on how the vase supports a flower. 

When the flower leans on the vase for support, they provide a comfortable sense of unit helping each other. 

When the vase supports the leaning flower from underneath in one spot, they provide a little sense of tension around the flower. 

When the vase supports a branch from underneath in one spot, The beauty of the branch extending transversely is highlighted. 

The flower extending lengthwise. The leaning flower. The flower supported from underneath. 

I hope you enjoy the different impressions.
