#1 Lacy Phacelia

Lacy phacelia, which also goes by the common names blue tansy, bee phacelia, and lacy scorpion-weed, is a beautiful annual that originates from California and parts of Mexico. It is hugely popular in Europe for meadow and pollinator gardens, as its flowers are extremely attractive to bees! 

These plants have a long blooming season over spring and summer, producing fuzzy little clusters of purple-blue bell-shaped flowers with long, conspicuous dark purple stamens. Lady phacelias are easy to grow from seeds and will thrive in sandy, rocky soils under full sun conditions.  

#2 Lady’s Mantle

Lady’s mantle plants are a group of around 300 or so species that belong to the group Alchemilla. These beautiful plants are found worldwide but are most common in Europe and Asia. Several species have been highly cultivated as garden ornamentals for their sprays of greenish-yellow flowers. 

The most well-known in this group is A. mollis, a top choice among gardeners for cottage-style gardens. Like other members of the genus, it is a herbaceous perennial and has delicate clouds of chartreuse flowers. These plants form clumps up to 15 inches tall and are wonderful as a bed filler amongst more showy plants! 

#3 Ladybells

These plants belong to the genus Adenephora but are very similar to another group of lovely garden ornamentals, Campanula. There are 60 species in the group, and they are native to cool regions of Europe and Asia. The majority of ladybells have pretty blue bell-shaped flowers that grow along spikes or in loose clusters. 

Depending on the species, flower color can range from dark blue to pale violet. Since the group is large, different ladybells suit different climates. For example, A. confusa and A. lilifolia are hardy in USDA zones 3-7, whereas A. pereskiifolia are more suited for warmer weather being hardy in zones 7-9. These perennials are great for shady woodland areas or for planting around shrubs!

#4 Lantana

Lantana flowers belong to the verbena family and are a large collection of over 150 flowering evergreen shrubs. These wonderful flowers are native to tropical Africa and America, so are normally grown as annuals in colder climates. These plants are well-suited to container planting so their brightly colored flowers are fantastic for adding a pop of color to patios or balconies!  

They have long-lasting, vivid, tubular flowers that grow in tight little clusters. As their individual flowers mature, they change color, leading to an attractive bi-colored effect on their flowerheads! Lantanas are incredibly versatile, looking incredible in both tropical and cottage-style garden schemes. 

#5 Lamb’s Ear

Lamb’s ear is a fantastic herbaceous perennial for providing some ground cover! They belong to the mint family, Lamiaceae, and are native to the Middle East. They are relatively low-growing, only reaching 1.5 feet high, and have soft, velvet, silvery gray leaves. These plants get their common name because their fuzzy leaves are said to resemble a lamb’s ears! 

These plants are prized mostly for their foliage, but in late spring to early summer, they produce little purple-pink flowers on stems that rise above the foliage. Since their flowers aren’t particularly spectacular, many gardeners remove them come blooming time to enhance the plant’s effect as ground cover.

#6 Larkspurs

Larkspurs are showy annuals that belong to the genus Consolida. They are often confused with delphiniums due to their similar appearance, however, larkspurs are botanically a separate species. Over summer, they have beautiful spikes that are adorned with delphinium-like flowers!

C. ajacis, or the common larkspur, is one of the most commonly grown in the group and will grow as tall as 4 feet with blue, pink, or white flowers. Larkspurs are perfect for cottage-style garden borders and will do well in full sunshine, tolerating some light afternoon shade in particularly warm climates.

These evergreen shrubs have probably one of the most recognizable scents in the world and are native to the Mediterranean and bordering countries. There are 30 species in the genus Lavandula, which is within the mint family. Lavender bushes are extremely distinct, with gray-green leaves and purple flower stalks growing at the tip of bare stalks. 

Some of the most widely cultivated species are French lavender (L. stoechas), English lavender (L. angustifolia), and woolly lavender (L. lanata). Although these wonderful shrubs are grown commercially on a large scale, lavender is still incredibly well-loved by gardeners, particularly for cottage-style and coastal gardens.

Liatris plants, commonly known as blazing stars or gay feathers are part of the genus Liatris. This genus comprises around 40 species, all of which are perennials that are native to North America. In the past, these plants were most well-known under the name colic root, which refers to their medicinal properties.

Over summer, they have bold flower spikes that have a bottle-brush appearance and are tightly packed with either pink, purple, or white feathery disc flowers.

#9 Ligularia

This group of roughly 150 species is also known as leopard plants. They grow between 3 and 6 feet tall, with bold green to dark purple foliage and yellow to orange colored daisy-like flowers. Their flowers either grow in flat-topped clusters, narrow flower spikes, or tall tapered flower spikes.

Ligularias are mostly native to Asia and are winter hardy in zones 4-8. They do well in heavy shade and wet soils, making them particularly well-suited for moist woodland gardens, shady rain gardens, or pond and stream landscaping!  

#10 Lily

These plants hardly need introduction as they are one the most famous bulbous perennials, but lilies, from the genus Lilium, are a group of between 80 and 100 species. The common name lily is often used to describe plants from other genera with lily-like qualities, but true lilies are upright plants, usually with narrow leaves, and solitary or clustered trumpet-shaped flowers that have 6 petal-like segments.

#14 Lords and Ladies

Sometimes called cuckoopint, lords and ladies are shade-loving perennials that can be found throughout Europe, north Turkey, and west Caucasia. These plants are highly poisonous to people and animals, but that hasn’t stopped them from being a top choice for woodland and shade garden borders!

Once the blooming season is over, the spathe withers to reveal a cluster of attractive, bright red, but highly poisonous berries.
