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.
Uses for yellow coneflower, perennial black-eyed Susan: Great flowers for the wild garden or for naturalizing in the meadow garden, Goldsturm is best for the formal bed or border and should be planted in drifts. These flowers are perfect when used in combination with the variegated ornamental grasses. They are also excellent for cutting. Yellow coneflower, perennial black-eyed Susan related species: Rudbeckia laciniata, or the green-headed coneflower, is valuable for a wild garden. Goldquelle or, as it's sometimes called, Gold Drop has big, double flowers on 24- to 30-inch stems.
