Much less aggressive than the species, Lysimachia punctata 'Alexander' (Yellow Loosestrife) is a perennial plant with stunning ornamental value, producing sturdy, upright stems loaded with striking variegated foliage consisting of whorls of lime green serrated leaves with bright creamy edges that emerge with a pink blush in spring and age to white. Masses of cup-shaped, golden yellow flowers, tinged in red at their heart appear in early summer for a long blooming season ending in late summer. Easy to grow, this Yellow Loosestrife is excellent at providing a fast-spreading cover when required, creating great visual impact.

• Vigorous, this rhizomatous perennial reaches 2-3 ft. in height (60-90 cm) and across. Undemanding, this Yellow Loosestrife spreads by rhizomes to form colonies, but will only occasionally produce seed and will not come true from seed.
• Performs best in full sun or part shade, in humusy, moisture-retentive soils. This plant will require partial to full shade in hot summer areas. Drier soils are tolerated in partial shade, but they should never completely dry or the variegated leaves would quickly turn brown at the edges.
• A perfect plant for beds, borders, cottage gardens, or coastal gardens. Excellent as long-lasting cut flowers!
• Yellow Loosestrife is generally not subject to serious pest or disease issues. Watch for slugs and snails.
• Remove faded flower stems for a neat appearance. Vigorous plants can be divided in the spring or fall.

There are up to 180 species of Lysimachia. The genus includes hardy to frost-tender perennials, either herbaceous or evergreen. Their habit can be upright or prostrate, with some forming excellent ground covers. Their flowers are variably shaped and are usually yellow or white, but sometimes pink or purple. Many species are invasive, but this tendency can be harnessed to produce large stands, creating greater visual impact.
