Instructions
Build five apples from your inventory list. At the point where you are ready to build potted plants, you should already have the apples blueprint. Use the blueprint to build the apples.
Send a friend request to Henrietta. Go to her page and then click on "Add to Friend List." Click the "Refresh" button in your browser's toolbar to see when Henrietta has accepted your friend request.
Go to Henrietta's Trade Module to buy the "Mason Jar Blueprint" with the apples you just built. Go to your inventory and use the Mason Jar Blueprint to build two Mason jars.
Send a friend request to Bee Keeper Bill. Use the same technique you used to befriend Henrietta. Buy the "Worker Bee Blueprint" from Bee Keeper Bill. You will need to trade him the two Mason jars for the blueprint.
Become friends with Flora and build three "Worker Bees." Use four red Lego bricks to build each Worker Bee. Use one of the Worker Bees to trade with Flora for the "Flower Patch Module Blueprint." You will need to send her the Worker Bees through your mailbox.
Spend 15 red Lego bricks to buy a "Flower Patch Module."
Go back to Flora's page and give her your other two Worker Bees for the "Potted Plant Blueprint." Use the "Mason Jar Blueprints" to build another mason jar. Use the "Potted Plant Blueprint," a "Mason Jar" and the red flowers from your "Flower Patch Module" to build the potted plant.
