The goal is to find care, environmental, and geographical information on annual plants in the US.
Annuals are plants that die and must be re-planted every year. They have
longer bloom periods
than perennials that last from early spring to the first frost.
Annuals are distinguished as either
hardy or half-hardy
. Hardy annuals can be planted
, while half-hardy annuals must be
of hardy annuals include Larkspur,
of half-hardy annuals include Dahlias, Geraniums, and Begonias.
While larger annual plants are usually grown outdoors in gardens, smaller or trailing annuals can be
It is important to
that prefer either sun or shade based on the location they are being planted in. Different annuals have
different light preferences
, some annuals prefer daily moisture while other prefer drier soil.
Annuals that are planted before they have bloomed will typically
in a garden.
Fertilizing is essential in growing annuals as they are considered "
Annuals have different zones that they prefer to live in, called
. These zones are based on a location's
extreme minimum temperature.
The zones have numbers that range from
1a to 13b
, which coordinate with temperatures ranging from
-51.1 C to 18.3 C
has zones including 3b, 4a, 4b, and 5a, and goes all the way up to 7b.
Each annual has a different hardiness zone that they can grow in. For example, the Flanders poppy is "hardy" in zones
