One of the best ways of searching for new plants to try in your own garden is to approach it alphabetically.
It may sound strange, but using this method you are more likely to come across plants that you haven’t tried before, rather than lists of specific garden type plants, which can include the same species of plants over and over.
Plants that fall under the Aconitum genus are referred to as Aconite, Monkshood, or Wolfsbane. These names are used interchangeably, across more than 250 different species, giving you plenty to choose from!
Aconites are instantly recognizable for their hood-like flowers, most commonly found in true blue or dark purple, but they can also be ivory, pale yellow, or white with a green tinge.
These plants are herbaceous perennials, and do well in borders, beds, and containers.
It is worth noting that any form of aconite is not suitable for gardens which have pets or children. These plants are incredibly poisonous.
The reason for this is that high levels of aconitine and other alkaloids are present in the plant, which, if ingested, even in small amounts, can cause heart problems, vomiting, and death.
African daisies are beautiful plants that brighten up any garden. While they can survive in partial shade, they do their very best in full sunlight, where you will get the most flowers possible.
While there are many plants that come under this name, the one most people refer to as the African Daisy is those that belong under the Osteospermum genus (see also At A Glance: Osteospermum).
Most African daisy plants within this genus are perennials, and they do well in containers, rockeries, or as part of a mixed border, as long as the soil drains well.
They come in all sorts of colors, usually bi-colors, and they are a favorite of pollinators.
They aren’t demanding when it comes to the soil type, as long as water doesn’t sit around the roots for too long.
Among one of the most striking plants on this list, the Agapanthus is a lovely, fuss-free flower which will spring up every year from a bulb.
Grow them in well-draining soil in full sunlight, and they will provide your garden with plenty of color. You may also see them labeled under Lily of the Nile, and the Star of Bethlehem.
Ageratum plants belong to the daisy plant family. These lovely flowers are grown across the world for their ornamental value.
You might see it labeled under flossflower, bluemink, blueweed, or the Mexican paintbrush.
Most species are annual varieties, treated as cool season bedding plants (see also Cool Flowers To Extend The Flowering Season) to fill in gaps in beds and containers.
The flower heads are usually blue, though they can also come in purple, pink, or white, depending on the cultivar you choose.
Flossflowers are great for dry gardens that don’t see a lot of rain, or for gravel gardens. For best results, grow them in slightly acidic but well-draining soil, in full sunlight.
Also known as Lady’s Mantle, Achemilla vulgaris is a robust plant which grows quickly, and you may be surprised to know it is part of the rose plant family.
It produces fan-shaped foliage and airy, lime flowers in summer.
It’s often used as a ground cover in well-draining soil, either in a partially sunny position, or in full sunlight.
It’s worth noting that some people regard it as a weed. While it has had a lot of historical applications in medicine, it’s considered invasive in some places, so make sure you check with your local authorities before you plant it.
Alliums are beautiful plants that grow from bulbs. These perennials add architectural interest into any garden, forming spherical flower heads which last for weeks at a time.
They usually come in shades of purple or blue, but you can also find them in pink, white, or red.
Alliums are frequently used as companion plants, as their scent repels slugs and snails.
You’d be forgiven for thinking that an Alstroemeria is a true lily, with its common name being the Peruvian lily (see also Peruvian Lily Care Guide), and the speckles present on each bright flower.
Instead, this striking plant comes from the Alstroemeriaceae plant family, and hails from South Africa.
Flowers are typically orange, yellow, pink, or red, sure to brighten up any sunny part of your garden, as long as the soil drains well. Alstroemeria plants are perennials, which die back during the winter and emerge again in spring, flowering during the summer.
They are also a favorite of florists everywhere, thanks to their long life as a cut flower.
Also known as the carpet flower, Alyssum produces a plethora of tiny blooms in shades of white, blue, purple, and pink. Most types are cool weather annuals, but you also get biennial and perennial varieties, too.
It does well in both full sunlight and partial shade, and requires damp but well-draining soil, where it will flower from spring until autumn.
Because its growth habit is so vigorous, it’s often classed as an invasive species, so do check with your local authority before you plant it.
Amaranthus plants are short-lived, and vulnerable to frost, but don’t let that put you off. These striking plants are grown across the world both for their ornamental value and for their edible uses.
You’ll typically see them referred to as ‘Love Lies Bleeding’ because of their cascading red or deep pink blooms, draping down towards the ground. They also make lovely cut flowers.
It also helps that the leaves taste a little like spinach, and contain high levels of iron and vitamin C.
The seeds are also edible, where they are regularly grown for their nut-like flavor and high levels of calcium and protein.
It’s worth noting that if you live somewhere that doesn’t get frost, amaranthus can be classed as an invasive plant.
Amaryllis bulbs are among the most popular spring flowers (see also 60 Best Spring Flowers), with plenty of shades to choose from. These striking plants can come in crimson, baby pink, white, and orange, or a combination of these.
One thing you’ll need to make sure of is that you don’t bury the bulbs. Like hyacinths, they don’t like to be planted too deeply, which means that the stems will need some support.
Anemones are beautiful flowers that bloom in spring or summer, depending on the type you go for. They’re easy to grow and require very little maintenance.
They’re also available in many colors including white, pink, red, purple, yellow, orange, and brown.
Some anemones can get as large as a foot tall, while others are treated as ground cover plants.
Angelonia plants are annuals that flower in the summer months, reaching a maximum of 2 feet tall. They are great for flower beds, borders and containers.
It’s a great choice for climate-conscious gardeners or those whose gardens don’t see a lot of rainfall, as these plants withstand dry spells once their roots have established themselves.
One thing they absolutely will not tolerate is waterlogged soil. If the soil in your garden holds onto water for too long, you can try growing this plant in a pot, where you can change the soil type easily.
It also helps that containers don’t retain moisture as well as the ground does.
Anthuriums are very popular indoor plants. You’re probably most familiar with the flamingo lily, or Anthurium andreanum, with its heart-shaped foliage and unusual flowers or spathes (for more exotic flowers, see also Top Exotic Blooms).
These blooms come in a huge range of colors, including burgundy, white, scarlet, pink, and orange.
They are easy to care for and don’t require a lot of water, but you should not allow the soil to dry out completely.
Give these gorgeous plants a bright position away from direct sunlight, drafts, and sources of heat, and they will provide your home with beautiful color.
They also benefit from high levels of humidity, which helps replicate their natural habitats in the rainforests of South America.
Some anthuriums are grown purely for their eye-catching foliage.
Antirrhinum majus might not be a name you’re familiar with, but I bet you’ve probably heard of the snapdragon.
Snapdragons (see also Growing Snapdragons) are a type of flower that blooms during summer, all the way through until the first frosts. These flowers have been a firm favorite as ornamental plants for hundreds of years.
They are very easy to grow and thrive in many different environments. They are also very popular because of their beautiful colors and shapes.
Snapdragons are very popular because they have a good resistance against powdery mildew, which makes them ideal for humid or somewhat shady gardens.
Aquilegia, also known as the columbine (see also Columbine Flower Meaning), or the granny bonnet flower, are fantastic plants that will provide a lot of color into any area of your garden.
They don’t mind partial shade or bright sunshine, as long as the soil drains well. The name Aquilegia comes from the Latin word “aquila” refers to the petals that look like an eagle’s claw.
These lovely, fuss-free flowers are available in a wide range of colors, some of which are bicolored. They also attract bees into your garden, which helps benefit the overall health of your own green space.
Also known as common milkweed (see also Asclepias Guide), this plant is grown in many parts of the world for its ornamental value.
It is a member of the dogbane plant family, and the flowers contain a lot of nectar, which makes them a favorite of butterflies. This is where the name butterfly weed comes from.
In its natural habitat, it can get to well over 5 feet tall, producing leaves which can get to a maximum of 28cm long.
The flowers are highly fragrant, making them perfect for near patios, windows or doors where you can maximize on their lovely scent.
Asters are available in many forms (see also Types Of Aster), from herbaceous perennials which come back year after year, annuals, which fill in the gaps in your beds nicely, and subshrubs.
Some varieties are widely grown for their ability to flower well into fall, when most vivid flowers have faded. Some are perfect as ground cover plants, while others get much taller.
They are great for well-draining, sunny positions in your garden.
If you’re looking for more unusual flowers, astilbe plants are the ones for you. They produce fluffy, feathery flower spikes in a range of different colors, and prefer damp soil which is packed full of nutrients.
They do require some shade during the summer, especially from the midday sun, but they are well suited to living under large shrubs and trees, as long as the soil has plenty of nutrients.
There’s a variety suitable for every garden, with some staying small and compact, suitable for containers or small gardens, and there are also some varieties which can grow as tall as 72 inches.
They also make the perfect cut flowers, with their unusual form and bright, uplifting colors.
Astrantia flowers are also known as Masterwort. Most varieties bloom during the summer months, putting on a great display with their starry flowers in many colors, including purple, white, red, blue, and pink.
Astrantia is a fairly compact plant which does best in a mixed border in partial shade. This plant prefers damp soil, though you can get away with dry soil if you water the plant regularly, or if the roots go deep enough into the ground.
The flower heads are striking, and make the perfect cover for the messy bases of large shrubs or much taller plants, providing a wealth of color and interest into the lower levels of your garden.
Also known as rock cress, this lovely plant is a semi-evergreen which will provide your garden with color for years to come. It’s often used to border paths, where its vivid flowers spill over and trail along the edges of walkways, or between stepping stones.
You’ll frequently find it in shades of bright purple or yellow, and this plant produces such an abundance of color that it regularly completely obscures the foliage.
Aubrieta deltoidea grows to a maximum of 10cm tall, spreading to about 2 feet wide. This plant likes well-draining soil and the sunniest position possible.
Once the roots of the plant have established themselves into the soil, it can also withstand long dry spells without a lot of problems, too.
