What makes a plant an annual
or perennial, and what does it mean to be an herbaceous perennial?
Annuals last only one year at most, although some reseed readily
like cosmos and cleome. Perennials that die back to the ground
in winter are considered herbaceous while perennials like trees
and shrubs are called woodies. Bear in mind that some herbaceous
perennials in the Washington, DC area may produce woody tissue
if they grew in a warmer climate. For example some Fan Palms may
over-winter in a warm protected location in the city, even though
it will die back to the ground.
At American Plant you’ll
find all of our woodies in the Nursery Department, while annuals
and herbaceous perennials are in the Bedding Plants Department.
MARKETING
CONTAINER PLANTS
If you go into
a grocery store to buy canned tuna fish there are all different
brands, sizes, types and prices. You may buy the brand you always
buy, the one that looks the best, or you might buy using a price
by volume. Now required by consumer information law, container
plants sold in garden centers require comprehensive measurement
labels and advertising information. You will start to see labels
with the container identified by traditional measurements (diameter)
but also net contents by minimum volume. As an example, Annual
Market Packs are established as 6 cells; each cell has a guaranteed
minimum volume of 12 fl oz (345ml), so the market pack has a minimum
volume total of 2.25 qt (2.12L). In addition, each vendor may
have different volume measurements also. It’s a lot of information,
but it gives you a guaranteed size for your money no matter how
you measure it!
