"Rare Summer Egg Grow a Garden" kits are novelty items that combine the surprise of a growing toy with the fun of gardening. These kits typically feature a ceramic or plastic "egg" that, when submerged in water for a specific time, slowly cracks open to reveal a small, compressed soil pellet and plant seeds inside. The plant is usually a fast-growing variety suitable for summer, like sunflowers or herbs. These kits are popular as gifts for children and adults alike, offering a unique and engaging way to experience the wonder of plant germination and growth, albeit on a miniature scale.
