Is there another choice to plant to get Roxy besides using the Radiant Roxy Rose seed?

You plant the Radiant Roxy Rose seed in your Moshling Garden, just like you plant any seeds. Click on the red seed bag on the right side to open it, then click and drag the Radiant Rosy Rose Seed and any two other seeds to the mounds of dirt in the garden. Wait for 6 hours for the seeds to grow into plants and you will attract Roxy to your garden!
