The hobby I have is growing orchids and I thought it would be good to learn the phrases that would be common to it. Since both really interest me, I thought they would reinforce each other. We are having an orchid show in a couple weeks and I've invited my teacher to it and thought "wouldn't it be great if I could give her a tour of the different flowers using only Japanese"?
So this is where I'm hoping to get some help from the forum. My teacher is on vacation for the next two weeks so this will all be self study. I'm not looking for really complex sentence structure (right now) but would like to be able to lead a tour and probably point out the really obvious.

1. This flower is called a Cattleya.
2. This pink flower smells really nice.
3. This flower smells like vanilla. (or chocolate or fruit)
4. This flower is mine.
5. This flower is easy to grow.
6. This flower is my favorite.
7. Do you like how this one smells?
8. Is this flower pretty?
9. This is not an orchid. It is a fern.
I would like to try a couple of them; please pardon the romaji.
1. Kono hana-ga Cattleya desu.
2. Kono pinku hana-ga totemo nioi ga shimasu.
3. Kono hana-ga banira nioi ga shimasu.
4. Watashi-no hana-ga arimasu.
8. Kono hana-ga kirei desu ka?
9. Kore-wa ran-ga deshita. Shida desu.
I had to use the dictionary to look up some of the words, and I'm sure I messed up the ga/wa particles, but I would really appreciate your critiques and suggestions or even some other phrases that would be related.
Thanks!
