No. Some people think that you get Roxy with a Rox flower but actually you don't. The only things Rox flowers are good for is getting Rox if you don't have many, but they don't give you that many Rox anyway.
The amount of Rox you get from a Rox flower is random. The happiness of your monster has no effect on the amount of Rox.
You can not attract a moshling with Rox flowers on Moshi Monsters. Instead, you get Rox when you dig up the Rox flower.
You can not attract moshlings with Rox flowers. If you click on/dig up the Rox flowers, they will give you Rox which you use to buy things for your Moshi Monster.
To get Rox from a Rox flower in your Moshling Garden, wait until the flower is fully grown and then dig it up.
A Rox Flower appears randomly. It grows then you get 1-100 Rox and it depends how much health you have. The Rox flower looks like a bunch of Rox on a stem with leaves.

Its simple, you can't get 5000 Rox on a Rox flower. Your maximum Rox with a Rox flower is 50.
You don't shake a Rox flower. When you go into the Moshling Garden and you have a fully grown Rox flower, dig up the flower to get a random amount of Rox.
You can not attract a moshling with a Rox flower. Dig up the Rox flower to get a random amount of Rox, then plant another seed to try to attract a moshling.
Nothing, rox flowers just give you rox, they do not attract a moshling. You will need to dig it up.
