I'm stumped. Over the course of two years I planted 7 or 8 various echinacea. They came up, flourished and even self seeded for a year or two and then, for no apparent reason, two years ago not a single plant came up. A few of these were pretty healthy, large specimens. The care they received was always consistent and I never use herbicides or insecticides near them. Have UFO's invaded my garden and carried them away?
