1. Lily of the Valley

This unique plant is not part of the lily family - but rather the asparagus family! It is best grown in zones 3-9 and loves moist soil. It can produce red berries, although they are poisonous when ingested.

One of the most interesting facts about the lily of the valley is that there is a whole day dedicated to these flowers! The history goes back to the 16th century when the king of France would gift lilies of the valley to women in his court.

As the tradition continued, May 1st, 1561 (the day the king first knew of these flowers) became known as Fête du Muguet. In more modern history, Europeans celebrate this holiday as May Day, the middle between the spring equinox and summer solstice.

2. Black Willow

The bird is facing towards the left and looking slightly downwards. The tree is covered with green leaves and long seed pods.

Black willow trees are known for being flood-resistant creatures. Not only can they tolerate the buildup of sediment, but the tree can help stabilize the soil after a flood.

In addition, many people may plant a black willow tree to control erosion damage. In the springtime, black willows are one of the first places bees can stop to fill up on pollen and nectar.

If you're looking to plant a black willow tree, it is best to ensure that your location will receive at least 51 inches of annual rainfall. You also may want to invest in a few pest repellants to drive away caterpillars.

3. Inkberry

Look at those berries! These little guys crave full sunlight while they grow above moist, acidic soil. Humans can't eat them, but birds are thankful for them during winter.

Inkberries are often planted as a boxwood alternative, although they shouldn't be treated like a second-class plant. The evergreen inkberry holly continues to provide for native wildlife throughout harsh freezes.

Note that this plant has both a male and female holly variety. The shrub must have both male and female flowers to produce fruit.

They are not self-pollinating, which means they will also require the aid of bees and butterflies. Try planting companion flowers like begonias or geraniums to attract pollinators to your garden.

4. Arugula

A salad staple and beloved herb, arugula is the fourth plant that enjoys moist soil. The growing zones range from 2-11, and the growing season is rumored to be all year long.

If you're not a big fan of the earthy taste, the smell alone deters pests! That makes it a great companion plant for everything else featured here.

The nutritional value of arugula heavily contributes to why people grow it. It is rich in iron, zinc, and magnesium and is a cancer-fighting food.

It is part of the brassica family, including other nutrient-dense vegetables like Brussel sprouts and kale.

5. Scarlet Swamp Hibiscus

Swamp Hibiscus also known as Scarlet Rosemallow and Texas Star Hibiscus.

The scarlet swamp hibiscus is a flower that can't get enough water! Often placed on the edge of ponds, this strikingly red flower finds itself in full bloom during the months of late summer and early fall.

Flowers may fall off after only a day of blooming, but a new blossom will soon replace them. The plant can grow up to 6 feet tall and 4 feet wide, although it is often trimmed down to a size that better suits its location.

The companion plants for the scarlet swamp hibiscus include all other types of hibiscus. The hibiscus family thrives in numbers, but it is also essential to preserve biodiversity.

We recommend trying daylily, sweet alyssum, or poppies. For more information on hibiscus care, visit our post here: My Hibiscus Is Dying - What To Do?

6. Cinnamon Fern

The fronds of a cinnamon fern resemble cinnamon sticks, as the name suggests. When the fronds unfurl, they can reach 2-4 feet in length.

Historically, indigenous peoples have used cinnamon ferns to aid rheumatism and snake bites.

To care for them, be sure they are placed in an area that receives both partial sun and shade throughout the day. This plant does not spread quickly, so it shouldn't take up too much space in your yard.

7. Goatsbeard

This funky plant grows best in zones 3-7 and is often cultivated as a border plant. Deer and other common pests don't care for goatsbeard, although it does attract native bees!

Native bees are often praised as better pollinators than honeybees. Goatsbeard only grows to about 4 feet wide, which makes it perfect for controlling the garden borders.

A few companion plants for goatsbeard include bleeding hearts, lamb's ears, and delphiniums. Remember to plant what makes sense for your garden! One plant may work better for your space than another.

8. Sweet Flag Grass

Also called "acorus," sweet flag grass is a beautiful evergreen.

The Acorus calamus grass variety is commonly found in wetlands. That makes for a showy plant with its intricate yellow blossoms. Other flag grasses are ornamental garden grasses.

You might be wondering why this one is called Sweet Flag Grass. Well, the Latin translation is roughly "aromatic grass." You can understand why when the plant is crushed up or ground.

A sweet, earthy, herbaceous smell is produced by sweet flag grass. We encourage more people to incorporate this magnificent plant into their woodlands and ponds.

9. Red Chokeberry

Guelder rose (Viburnum opulus) is also known known as dogberry and water elder. Certainly, this bush of some 3 or 4 metres in height was growing beside a stream. The name guelder comes from the Dutch province Guelderland. Guelder rose belongs to the same flower family as honeysuckle, and is a typical British woodland shrub. The white flowers form in clusters, with large infertile flowers on the outside and creamy, fertile ones in the inner. In autumn, the central flowers develop into drooping clusters of juicy red berries, each with a single seed. Although the berries look very similar to redcurrants, and attract wildlife, they are poisonous to humans unless they are cooked first. This photograph uses selective focus.

The chokeberry gets its name from the puckering face that comes with the taste. In berries and wine, this is called astringency. The berries are deep red and glossy.

The red chokeberry is a native shrub that can provide food for wildlife in the fall season. Birds won't eat too many chokeberries, but rabbits and deer enjoy them!

Red chokeberries can be eaten by humans as well. Although, because of the bitter taste, they are often not found in the kitchen. When they are used, however, it is usually in the form of syrup or jam.

The sugar content is high enough to mask some of the astringent flavors.

10. Fern Leaf Bleeding Heart

This plant is found in zones 3-9 and will only grow to about 1-2  feet tall and wide. While deer and rabbits are tolerant, the common pests found under the shrub include slugs and snails.

Redirecting them using natural methods is important because they contribute significantly to our environment's biodiversity.

This plant is a show-off. The foliage is green with a blue undertone, and the flowers begin to bloom in early fall. The flowers will continue to show off their delicate pink petals until late spring.

The benefit of planting bleeding hearts is that they attract bees and hummingbirds. Unfortunately, ingesting this plant can cause serious harm.

Beware of wandering toddlers: they experience the world with their mouths!
