Annuals with Staying Power

We’re now past mid-October and have suffered several nights near freezing here in Northeastern Massachusetts. As I walk around the yard and look at the gardens, most of my late-blooming perennials have already called it quits and are bedding down for the winter under a soft blanket of leaves. But wait! Amazingly, there are still some plants blooming, and even more amazing is that they’re all tender annuals!

Annuals are plants that are not hardy enough to survive New England winters but even though they are short-lived, many are happy to spread their seeds around, so watch for little volunteers come spring. Unlike perennial plants that return year after year, annuals have one season of life but, boy, do they make the best of it in terms of flower power!

Strongly scented MARIGOLDS are classic cottage garden plants and I’ve grown them every year since I started gardening! Their cheerful blooms can be open discs, prettily ruffled posies or rounded powder puffs in colors that range from white and yellow to dark red and even bicolors. Marigolds are reputed to repel pests in the vegetable garden such as root-devouring nematodes and tomato hornworms as well as rabbits and deer. They also attract beneficial insects such as bees, butterflies and tiny wasps.

Annual sage or SALVIA is another long bloomer that comes in colors ranging from white, pink, red and blue to the deepest purple. Although many are in the 12 to 18-inch height range, perfect for pots and the front of the border, some can grow to an impressive 40 inches. You can learn more about the striking salvias I grew this summer in my blog A Tale of Three Salvias but let me just say that as of today all three are still a strong presence in the garden.

Sun-loving ZINNIAS are prolific bloomers that come in a huge array of sizes, colors, and flower shapes. In my Zone 6 garden, zinnias can be slow growers until the weather really heats up in July but, once they get going, they’re unstoppable. This year I planted zinnias from the aptly named ‘Profusion’ series and was very pleased with their vigorous habit and abundance of blooms. Heat, drought and mildew resistant, these zinnias are extremely long-lasting in the garden as well as in bouquets, and every garden should include some of these beauties!

EUPHORBIAS are not as well known as other annuals but have become more popular in recent years. ‘Diamond Frost’ and ‘Diamond Mountain’ are two varieties that don’t disappoint in their vigor and resistance to disease, heat, drought and even cold. Their delicate appearance belies an extremely tough constitution! The tiny white flowers are produced in abundant sprays all season long and create a cloud of sparkling blooms that contrast nicely with other plants. I like to use euphorbias as an edging to flower beds, as a filler in pots, or as an accent next to bolder leaved companions such as lavender or yucca.

Old-fashioned NASTURTIUMS bloom in colors ranging from the softest creamy white to the darkest red. They vary in habit from well-behaved bedding plants to large rambling or climbing vines, but they all sport rounded blue-green leaves and vivid flowers shaped like a woodland fairy’s cap. Nasturtiums grow best in full sun but they don’t like the intense heat of summer, preferring the cooler days of late spring and fall. Easy to grow from seed once the soil has warmed up, make sure to place them where you want them to stay since nasturtiums resent being moved. In fact, they seem to thrive on neglect, so it’s best to plant them and forget them, then sit back and enjoy the show!

These are just a few of the many beautiful annuals available to gardeners every year. This spring, find colors that you love, mix and match with perennials, and plant with abandon for non-stop blooms!

A Tale of Three Salvias

Every spring I plant several different annuals amongst my perennials and vegetables, and one that I return to faithfully, year after year, is the humble salvia. In today’s blog, I’ll talk about three different salvias that I planted and enjoyed this summer.

Ornamental sage or salvia is also known by the not-so-glamorous name of Mealycup Sage because of the powdery, meal-like coating on the flowers. Native to Texas and Mexico where they can grow into sizable shrubs, they are commonly used in the north as tough and reliable annual bedding plants.

Salvias are invaluable in the garden for their showy long flower spikes in shades of red, white, pink and blue which bloom non-stop until frost. They aren’t bothered by insect pests, tolerate a wide range of soils, grow in sun to part shade, and are heat and drought tolerant. Deer and rabbits also avoid them which is always a plus in my neck of the woods.

Since my late summer gardens are filled with the open, disc-like flowers of zinnias, marigolds, coneflowers and rudbeckia, the long spiky blue and purple flowers of my featured salvias provide a much-needed contrast in color and form. In addition, the bees and butterflies love them and hummingbirds can’t stay away!

I’ve always had a weakness for blue flowers and several years ago I fell in love with salvia, ‘Victoria Blue.’ About 18 inches tall, and perfectly sized for growing in pots as a focal point, ‘Victoria Blue’ also makes a stellar companion for hot-colored annuals in the garden.

In addition to my old friend, Victoria, I treated myself to two new salvias this year which I have never grown before – one blue and the other a deep purple. They are both Proven Winners varieties, a name I have come to trust for plants that don’t disappoint.

Salvia, ‘Rockin Playin The Blues,’ is very similar in appearance and habit to ‘Victoria Blue’ but grows much larger in size, from 24 to 48 inches tall. I thought this plant would be perfect next to my tall black-eyed Susans and I wasn’t mistaken.

The third salvia I planted this year is called ‘Rockin Deep Purple,’ an even taller variety that grows up to 40 inches with flower stalks of such a deep purple that they appear almost black when in bud. Stunning with tall white ‘David’ phlox and rosy pink spider flowers, ‘Rockin Deep Purple’ is a striking presence in my late summer garden!

With salvias, late summer into fall color combinations are almost endless. Try pairing with purple fountain grass, coreopsis, dahlias, autumn sedums and more!

Did you know that salvias can also be dried for fall arrangements? ‘Victoria Blue’ works especially well for drying, similar to lavender. Simply cut the flower stalks to the desired length when at their peak. Mid-morning on a sunny day is the best time to do this, after any dew has dried from the plants. Gather a small bunch of stems, tie with string and hang the bundles upside down and away from direct sunlight but where air can circulate around them. A wire coat hanger is great for this and can hold 3 to 4 bundles evenly spaced. Give them a couple of weeks to dry thoroughly and then use with other dried flowers in bouquets or wreaths!
