Can I cut the flower part off? Are there male and female plants?

You'll need the stamps, a piece of silverware, a hammer of some kind - I prefer a larger metal mallet type hammer (better to smash your fingers with), a magic marker, something to stamp onto (I used a small brass block that I found in the garage) and for safety you should wear gloves and safety glasses.

Instructions are below the photos and a much more detailed tutorial is on my blog post.

Oh, and I've had quite a few people asking on my blog about using them for weddings (stamping Mr. and Mrs. on forks or wedding dates, etc). Avery cute idea, BTW. I would say if you are expecting people to eat with them, I would skip the steps about using a magic marker, because that could be toxic. And you certainly don't want to start the marriage off on a bad note. If you still want to do the last step where you "color" them in a little, you could use liquid food coloring and wipe it into the letters a little.

Have fun stamping. Watch out for your thumbs and please wear you safety gear!

Here are some tips to get a Clematis started up your tree!:

-Choose a tree with rough bark, like a maple or oak. A smooth tree, like a cherry, with not get enough grip for your Clematis as it grows.

-Plant it on the shady side of the tree trunk and add compost. Mulch well. This enables you to give its roots the shade they need to start well.

-If you are not planting by another vine, then add a way for the Clematis to make it on to the tree bark. Use small bamboo canes, fishing line or twigs to make a scaffold for it to climb.

-Help the Clematis along by occasionally tucking its loose new growth into the rough bark of the maple.

It has turned out beautifully! I especially like the dreamy blue of Clematis 'Perle d'Azur' when viewed on the tree trunk against the blue sky. I hope yours does too!
