Looks hard, but it's not. Stamp, or draw, a flower stem with green ink. With pencil lightly draw a circle the size you want your flower to be, then either spread glue lightly over the area or use double-sised tape. Use 3 shades of tiny paper flowers and cover the surface and there you have it - a hydrangea! You can add any sentiment when you use the card.
This card required some work - I had seen the sentiment on another card, and really liked it - The tree and rocks were easy; I have those stamps - the tiny bear stamp that a friend had made it perfect!
I saw a card similar to this one in a magazine, but didn't like the sentiment used. I have a number of "sea and shore" stamps, so I just changed the format somewhat, and the colors used; then put my own sentiment on it. Time consuming, but worth it.
This one is my favorite - I used a cut out heart for a pattern, then drew a line around it, colored the primary one pink. Then I added a line of dots (with a pencil) on one side and added silver glitter to them, next I added a tiny cut-out heart. Last, but not least, I stamped the flourishes...
