Today is Trinity Sunday in the Western Christian liturgical calendar which celebrates the Christian doctrine of the Trinity, the three Persons of God: the Father, the Son, and the Holy Spirit. In various books, including the American Gardening published in 1896, the trillium is often mentioned in connection with Trinity Sunday and the wildflower is also called trinity flower. Nearly all parts of the plant comes in threes. It has 3 broad leaves on each stalk, 3 small green sepals and 3 large white sepals surrounding a group of yellow stamens plus it also has three-sectioned seedpods.
But this year my great white trillium blossoms has already turned pink or dropped their flower petals so only the nodding trilliums were displaying their white flowers yet.
