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.
Sunflower Cultivars. Cultivars best for edible seeds, called confection types, come from two types of cultivars with striped hulls. First are the tall cultivars that are everyone's stereotypical image of sunflowers -- plants considerably taller than a person with dinner-plate sized flower heads.aller sunflower varieties are best for producing large quantities of good-sized seeds for snacking. Mammoth Russian grows 12 to 15 feet tall with 15-inch-wide flowers and thin-shelled plump meaty seeds.
