Dried Out Bottle Gourd for DIY bird houses. Inside are heirloom seeds to plant in your garden. If you do plant the seeds make sure you give them a minimum of 4-8ft between anything you don’t want them to shade over. They grow like crazy! They have a very nice lemony squash taste if harvested when they are small and tender. ** This is an example of what you can make with the gourd in the photo.
