What is the difference between a spice and an herb?
Spices are flavorings, often of tropical origin, that are dried. Most spices
come from plant fruits, as is the case for mace, nutmeg, black pepper,
and cardamom. Cinnamon comes from the bark of a shrubby tree, and ginger
comes from the underground rhizome of a plant. Herbs, in the culinary sense,
are leaves of plants that can be used either fresh or dried to season food.
In the botanical sense, an herb is any plant that does not have woody perennial
stems like a tree or shrub.
What's the hottest pepper that I can grow?
The hottest peppers in the collection are the Capsicum chinense
cultivars 'Habanero' and 'Red Habanero', both of which register between
80,000 and 150,000 Scoville units. The Scoville unit measures the amount
of heat-producing chemical compounds, known as capsaicinoids, in peppers.
One part per million of capsaicinoids translates into 15 Scoville units.
Pure capsaicin rates 16 million Scoville units one drop of capsaicin diluted
in 100,000 drops of water is enough to produce blisters on the tongue.
Do you grow cannabis in the National Herb Garden?
No. Although Cannabis sativa has a long history of use in medicine
and as a fiber and oilseed crop, it is not grown in the National Herb Garden
because it is a controlled substance.
