Favorite or New Plant
Rearing its turtle-like heads of pink and white colored flowers in September, turtlehead (Chelone lyonii) is an easy to care for perennial that's blooming now. They are hardy to USDA zone 3 and grow to about 3 feet tall, blooming beautifully in part or full shade. Although at ease in the perennial border, it really performs best in swampy areas with rich soil near a stream or pond. Turtlehead has shiny dark green leaves and erect flower stalks, making it a great backdrop for other plants during earlier months.
Gypsy Moth Research
Scientists at the University of Wisconsin have discovered tiny amounts of an obscure antibiotic added to B.t. (Bacillus thuringiensis) used to control gypsy moths makes the B.t. more lethal. This is great news because it boosts the natural pesticide's potency and reduces the development of resistance to B.t.
