Practiced by organic gardeners for years, companion planting has become very popular for all gardeners. The concept is to plant together species that will benefit each other, to help prevent disease and insect infestation without the use of chemicals. In general, herbs and other aromatic plants like tomatoes, marigolds and onions are helpful in warding off insects. Certain colors, like the orange of nasturtium flowers, are thought to repel flying insects. While these practices have not been scientifically proven, many gardeners have been using them for years with positive results. Try it – and see if it works for you!

Are you looking for new perennials to add to your landscape but are tired of the same old plants with dull blooms, predictable foliage and raggedy forms? Dianthus ‘Firewitch’ can be the answer that will bring unique texture, brilliant color and clean lines to your flowerbeds.

About the Plant

Dianthus plants – also called sweet williams or pinks – are well known in landscaping, but ‘Firewitch’ is even more spectacular than most of these familiar perennials.

Dianthus ‘Firewitch’ (sometimes called cheddar pink) is a low growing, mat-forming plant with evergreen, narrow, bluish-gray foliage with a spikey texture that adds a bold statement to the landscape. Growing 3-4 inches tall, this perennial forms a mature clump at 6-12 inches wide. Brilliant purplish-pink flowers reach 6-8 inches high and cover the plant at bloom time. The petals are also spiked, which gives this plant an even more stunning, sharp appearance.

Described as hot pink, purple red or magenta, the flowers provide a striking contrast with the foliage during peak bloom in early spring. The flowers perfume the air with a spicy, clove-like fragrance that is even more noticeable in large beds or borders. ‘Firewitch’ is also tops in offering a re-bloom throughout the season, bringing brilliant color to the landscape for far longer than many other cultivars, even into mid-summer.

Growing Dianthus ‘Firewitch’

This perennial does best in full sun in well-drained, slightly alkaline soils, and can even thrive in sandy soils and is tolerant of moderate humidity as well as occasional drought conditions. Dianthus ‘Firewitch’ is excellent as a border edger, in a rock garden, planted in wall crevices or as a ground cover on a sunny slope. It is at home in the herb garden, a formal border or a cottage garden, where butterflies will also welcome the beautiful blooms. Because this plant is deer-resistant, it is also a good option for landscapes that may be visited by unwelcome wildlife. Deadheading the plant after blooms fade will help encourage reblooming, and blooms may be produced up to 4-5 weeks in optimal conditions. ‘Firewitch’ is not typically plagued by pests or diseases, but crown rot can be a problem if the plants are too moist or planted in poorly-drained areas.

Low maintenance, easy-to-grow and brilliantly colorful, what’s not to love about Dianthus ‘Firewitch’? Add some to your landscape today and you’ll love the sparkle it brings to your yard!

Hybrid hellebores bring us all sorts of happiness. These are one of the first plants to bloom in the late winter and early spring and are available in flower colors of chartreuse, cream, white, pink, red and deep purple. Hybrid hellebores are also those rare and treasured perennials that provide year-round interest, giving you the most bang for your buck and brightening your landscape in every season. As evergreens, they never lose their luster, and their flower shapes and textures are quite varied for even more interest, with a cultivar to suit any gardener’s taste. What’s not to be happy about?

A Love Divided

To keep these plants healthy and thriving, and to increase your quantity, division is a necessity. It is important to divide these plants carefully, however, or else you risk sadness with fewer blooms, lopsided plants or even losing these gems. Fortunately, it’s possible for even a novice hellebore lover to divide their plants with confidence.

1. Divide hybrid hellebores in the spring when it is in bloom. This will also let you see how the blooms are positioned on the plant so you can divide shapes appropriately.
2. Choose a plant that has at least 5 flower stems. Each one represents a division and will give you great new plants to bloom.
3. Dig your hellebores up with a garden spade by inserting it deeply into the soil around the perimeter of the plant about 6 inches away from the outer stems of the clump. This will keep the root system largely intact and uninjured.
4. Lift the clump and shake off loose soil or any trapped rocks or ensnared mulch. You can gently loosen clumps with your fingers, but take care not to damage the roots.
5. With a garden hose, wash away any additional soil from the clump so the plant roots are exposed. This will help them get established in their new location more quickly.
6. Divide the clump by cutting through the roots with a heavy-duty serrated knife. Make your root cuts where you see obvious natural divisions between the flower stalks.
7. Replant your divisions at their original depth, in a shady location. Include plenty of compost in the planting hole for good nourishment. Water well and continue to keep soil from drying out until your new plants are well established.

Before you know it, you’ll have many more hybrid hellebores to enjoy! If you have a few too many, be sure to share the happiness by giving them to family members, friends, neighbors and anyone else who can fall in love with these beauties.

For many gardeners, it’s not the tulip or daffodil to forward to at the end of winter, it’s the sweet pea (Lathyrus odoratus) that declares, “spring is here!” The colors and sweet fragrance of these climbers announce the coming of warmer days like no other.

Choosing Sweet Peas

The hardest part of growing sweet peas is choosing from the riot of colors. From the palest of pastels to the most vivid of hues (including stripes), reds, pinks, white, blues, purples, yellows… the list seems endless. Many gardeners buy mixed packages of seeds to avoid the decision and to add a riot of spring color to the garden and landscape.

Beyond color, it is important to carefully consider different types of sweet peas. If the seed package says “tendril” this means the plants have small green growths to attach to a surface or netting to help the vine grow upright. This is how the taller sweet pea vines support themselves as they grow to 6′ (or even taller!), and they will need an appropriate trellis, arbor, arch or other structure to reach their full beauty. The varieties with no tendrils remain more compact, making them great in containers. Some of these will trail downward, creating a beautiful draping effect. Other dwarf non-vining varieties act as annual fillers in the mixed garden bed or as borders.

Growing Sweet Peas

These beauties are super easy to grow. To improve the germination rate, especially of the darker colors, use nail clippers to gently nick the seed coat and soak overnight before planting. This will allow thin shoots to pierce through the thick seed covering more easily so they can grow effectively. Sow the seeds 2″ deep in rich, well-draining soil in a full to partial sun location. If the soil is heavy, add compost to improve the texture and nutrition. Keep the soil moist, but avoid saturated soil that can drown small seeds or delicate roots. Germination should occur within 10-28 days. Continue even and consistent watering. When seedlings are 4-5″ tall, thin them to create 5-6″ spacing between plants. To encourage bushy and compact plants, pinch the tips when three sets of leaves form. Generally, do not provide additional fertilizer, otherwise the plants may be lush but the flowers will be sparse.

Impatient gardeners or those who may have a shorter growing season may also be able to purchase seedlings from a garden center. This way there will be fragrant sweet pea bouquets a month earlier, and there’s no need to miss out on the sweetness if the ideal seed planting date has passed. Removing flowers when transplanting will encourage stronger root growth to produce larger flowers later if desired.

Seeds for perennial sweet peas are also available. Unlike annual sweet peas, the perennial plant will continue to bloom throughout warm, humid summers. Be aware, however, that annual sweet peas tend to have a gloriously heady scent, but this is a feature sorely lacking in the perennial form.

Enjoy the Beauty

Those long-lasting, colorful and fragrant flowers are so sweet in large loose arrangements. They’ll easily last a week if the water is changed daily and a bit of the stem is snipped off each time to improve water uptake. Remember, the best way to extend the sweet pea blooming season is by daily picking early in the day. Or, simply enjoy these beautiful blooms by walking through the garden each day and relaxing in their delicious scent and colorful blooms.

Fall Flowers – Really!

Gardeners who just can’t get enough of annual sweet peas don’t have to mourn their loss in spring. Instead, grow them again in the autumn! These fast-growing flowers will thrive just as well in the cool autumn as they did in the early days of spring. Just remember to provide enough time for flowering before the first frost hits, and you’ll love using sweet peas to say goodbye to the gardening season in fall just as you said hello to them in spring.
