17 Gorgeous Flowers That Start With A (Including Pictures)

With approximately 400,000 species of flowers in the world, it’s understandable that even the most experienced horticulturists and gardeners are going to forget the names of certain flowering plants. From nicknames to scientific classifications, there’s always something new to learn about flowers. 

This means that if you’re new to the world of flowers, don’t feel too much pressure to remember the name of every species in your garden.

Putting flowers into categories (such as by color or flowers that share the same first letter) is probably the best way to learn the names of multiple flowers at the same time. 

Whether you’re looking to expand your garden or you’re trying to remember the name of a particular species, here is our list of flowers that start with A!

Exhibiting the beloved daisy-like appearance with disc and ray florets, these humble flowers are commonly planted in public flower gardens and along borders. 

Not only are African daisies favored for their array of brightly colored petals, but they are notoriously easy to care for thanks to their preference for rocky soils and neglect. 

5. Allium 

Allium

Allium is a genus of hundreds of flowering and non-flowering species, including onions, garlic, chives, shallots, leeks, and scallions. The flowering species, however, are also cultivated for their unique appearance.

Some species are ornamental onions that produce purple, pink, blue, yellow, or white globe-shaped clusters of flowers. 

Alliums are easy to grow. They typically prefer full sun but a tolerant or partial shade, and their bright coloring works to attract pollinators. Plus, they can be planted in rock gardens or cut for floral arrangements. 

6. Aster

Aster

Aster is a genus of around 170 flowering plant species and over 600 varieties. Most aster flowers are known for their distinctive daisy-like appearance with the ray floret structure and vivid coloration.

Not only do they range widely in color, but they also vary in size depending on the species, with the compact varieties suiting borders and taller species adding dimension and height.

The pleasant compounds of white flowers make Angelica species ideal for filling in the space of a border with some neutral colors. Angelica flowers are also used in holistic medicine, particularly in China where the species are mostly found. 

8. Amaryllis 

Amaryllis 

Amaryllis is a small genus of only two flowering bulb species, Amaryllis belladonna and Amaryllis paradisicola.

11. Angelonia
