Ornamental cabbage and kale (also known as “flowering” cabbage and kale) are in the same species (Brassica oleracea) as edible cabbage, broccoli, and cauliflower. While ornamental cabbage and kale are edible, they tend to have a bitter flavor and are often used in a culinary setting as garnishes. Ornamental cabbage and kale are prized primarily as colorful additions to home gardens where they are grown for their large rosettes of white, pink, purple, or red leaves.
Technically, ornamental cabbage and kale are all kales (kales produce leaves in a tight rosette; cabbages produce heads). But in the horticultural trade, ornamental kale is the term used for types with deeply-cut, curly, frilly, or ruffled leaves. Ornamental cabbage is the term used for types with broad, flat leaves that are edged in a contrasting color.
Ornamental cabbage and kale grow approximately one foot wide and 15 inches tall. There are many cultivars that are commercially available.
Note that wherever the number of seeds is indicated in grams, there may be more or fewer seeds in the package because the seeds are not the same size and weight.
If indicated in grams, the number of seeds loses relevance and is only there to show the approximate number of seeds in the package.
For example "Price for pack of 50 (1g) seeds." so you are not buying the number of seeds but the weight.
