As I\u2019ve been wandering through the woods this April and May I\u2019ve been trying to take photos of all the types of trilliums I see. Colourwise, I\u2019ve found white and red trilliums. As the white ones age, many will gradually fade to a light pink. The most interesting white ones had a broad green stripe down each petal.<\/p>\n<h2>Where Do These Green and White Trilliums Grow?<\/h2>\n<p><a href=\"http:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2015\/05\/WhiteTrilliumGreenStripesonNaturalCrooksDotCom.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-3347\" src=\"http:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2015\/05\/WhiteTrilliumGreenStripesonNaturalCrooksDotCom-400x312.jpg\" alt=\"Photo of White Trillium Green Stripes on NaturalCrooksDotCom\" width=\"400\" height=\"312\" srcset=\"https:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2015\/05\/WhiteTrilliumGreenStripesonNaturalCrooksDotCom-400x312.jpg 400w, https:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2015\/05\/WhiteTrilliumGreenStripesonNaturalCrooksDotCom-200x156.jpg 200w, https:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2015\/05\/WhiteTrilliumGreenStripesonNaturalCrooksDotCom-383x300.jpg 383w, https:\/\/naturalcrooks.com\/rambles\/wp-content\/uploads\/2015\/05\/WhiteTrilliumGreenStripesonNaturalCrooksDotCom.jpg 850w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><\/a><\/p>\n<p>Although I\u2019ve looked elsewhere, so far I\u2019ve only seen these white and green trilliums at Bronte Creek Provincial Park.
