Lysimachia punctata Alexander (Alexander Garden Loosestrife) Don’t let its common name fool you. This is nothing like the Loosestrife gone wild in our swamps and wetlands. Blooming in July-August here in zone 5b, it produces masses of cup shaped, bright yellow flowers. But it’s not the flowers that are the star of the show, it’s the foliage!!! While at the time of bloom the variegation is a striking green and cream, it is its earlier springtime foliage that is spectacular! Emerging with a pink blush to the foliage, Alexander’s foliage is spectacular in spring and again in fall as it is the cooler weather that brings out the warmer hue.
