1. Pinks

Commonly known as pinks, species of Dianthus plants are short-lived perennials that include sweet William and carnations. Pinks produce pretty, frilly flowers in shades of pink, red, lavender, and white and grow in full sun or partial shade.

Pinks can certainly be considered old-fashioned perennials, but there are some new varieties. ‘Testar’ is a lower growing variety that you can use around edges or like a groundcover. ‘First Love’ has flowers with unique coloring. They start white and transition to pink and then lavender. This new variety is also highly fragrant and resists fungal infections that affect many other types of pinks.

2. Nasturtium

Growing nasturtium flowers has long been popular because the annual is so easy to start from seed. This pretty edible trailing flower is native to South and Central America and can be grown as a perennial in zones 9 through 11.

You can find many varieties of nasturtium to grow, including heirlooms and new cultivars. ‘Jewel’ is unique for its double flowers. ‘Moonlight’ has pale yellow flowers and can trail as long as 16 feet (4.8 m), so you can use it to cover at trellis or in hanging baskets. ‘Troika’ varieties are award-winning and come in several different flower colors with unique variegated foliage.

👉 Nasturtium also works well in raised beds — see our article on Companion Planting for Raised Beds.

3. Spirea

Spirea shrubs are an old favorite and a popular choice of flowering shrub. One reason they’ve been so popular over the years is that spireas are easy to grow and forgiving of many conditions. While often considered old-fashioned garden plants, it’s worth checking out new cultivars of this old favorite.

‘Double Play’ is a series of cultivars with continuous blooms and outstanding flower and fall leaf color. ‘Pink Sparkler’ belongs to the Birchleaf series with leaves shaped like those of a birch tree. This one has pink flowers that bloom in early summer and again in fall. ‘Little Spark’ is a smaller variety with orange new growth that matures into yellow leaves set against deep pink flowers.

4. Rose of Sharon

Rose of Sharon is another example of a classic shrub that is often dismissed as old-fashioned. Related to hibiscus, these large flowering shrubs are easy to grow and produce abundant flowers.

Look for an exciting new variety called ‘Purple Pillar.’ It grows about 16 feet (4.8 m) tall and only 3 feet (0.9 m) wide, so it has a graceful, pillar-like growth habit that is ideal for smaller spaces. The flowers are bright purple and may be single or semi-double.

5. Ageratum

Ageratum flowers, or floss flowers, are known for their fluffy blooms. Grown as an annual in most locations, floss flowers bloom all summer long in a variety of colors, depending on the species and cultivar. One reason ageratum has long been popular is that it is one of the few plants with truly blue flowers.

‘Monarch Magic’ is a newer cultivar with a low, spreading growth habit. It has lavender flowers and attracts monarch butterflies. The ‘Hawaii’ series includes several flower colors, like white and bright blue, and bloom earlier and even longer than other types. ‘Blue Horizon’ is a new variety with long stems that make good cut flowers.

👉 Ageratum works well in pollinator mixes or meadows — see our Meadow Flowers & Grasses article.

6. Lady’s Mantle

Growing lady’s mantle may be considered old-fashioned and just for cottage gardens, but these tough perennials are always popular for a reason. They’re dependable, easy to grow and have unique foliage with airy clusters of small flowers.

Look for the cultivar called ‘Thriller’ for a more compact variety with yellow-green flowers. ‘Gold Strike’ is a newer variety that can be grown as a groundcover. ‘Robusta’ is a taller variety with sturdy, tall stems and large leaves.

7. Sweet Alyssum

This pretty perennial is often grown as an annual. It is popular for its mounding and spilling growth habit, which makes growing sweet alyssum for containers, edges, and borders an ideal choice. The abundant, small flowers have a very sweet smell.

Although sweet alyssum has been popular for years, new cultivars are being developed all the time. ‘Clear Crystals’ amplifies the classic type with larger flowers and a stronger fragrance. ‘Snow Crystals’ sweet alyssum is an award-winning cultivar that is extra robust and can be found in the Gardening Know How Shop. ‘Snow Princess’ was designed to be more heat tolerant. ‘Easter Bonnet’ and ‘Aphrodite’ series bloom earlier and include a range of unique and flower colors, including pastels, salmon, and red.
