Dietitians are the only qualified health professionals that assess, diagnose and treat dietary and nutritional problems at an individual and wider public-health level. They work with both healthy and sick people.
I have 3 different types of coneflowers: purple, yellow (Goldsturm), and orange (Sunset?). The purple I put in 2 years ago, and just isn't growing. It is still less than 5-6 tall with only 2 leaves, and surprisingly bloomed one pathetic flower. It still looks like the day I brought it home from the nursery.
On coneflowers, the most typical symptom is replacement of flowers by tufts of small, green, deformed leaves. Infected carrots roots may be excessively hairy and bitter, and in lettuce, inner leaves may be curled and twisted, whereas outer leaves do not develop fully and have pink or tan spots.
