An annual plant is a plant that usually germinates, flowers and dies in one year.
Some love annuals because they make excellent cut flowers; some because annuals are easy to grow; some love them for their brilliant colours while others just love to create a new garden every spring.
The reasons do not matter as they are all sound; if you love to garden and enjoy bright vivid colours then annuals will satisfy your needs. I am very fond of annuals and cannot imagine a garden that does not have a few.
They enlarge the palette but perhaps, more importantly, they enable me to make simple but noticeable changes to my garden and perhaps even better, they give me a reason to get out in the garden.
You can add annuals to your garden, throughout the growing season.
Annuals bloom continuously and produce prolific amounts of seed and this requires the production of many flowers; all making a win-win situation for any gardener.
