Perennials for Garden Borders

A border should house a combination of herbaceous, biennials and other herbaceous that wont die during winter, to avoid having an empty garden bed during those months. Some good herbaceous specimens to enjoy year round are; Brunnera, Helleborus, Heuchera, Nepeta, among others.

Combinations of plants should be well thought out to avoid having not matching compositions, and to enjoy the seasonal changes. Another aspect to consider is that an herbaceous border requires a large space to grow in, the answer for an average size garden is the mixed gardens. A good idea is to choose annuals with colour during the summer to share the herbaceous garden space, have some plants that don't die out during winter, and add other biennials and bulbs to the collection for a year round effect.

The size of the perennials are as important as the looks of it, a few examples of good border perennials to mix and match with other plants in a successful garden border are; tall frame plants, Acanthus, bear's breeches, the leaf motif of this plant is what is found on the Ancient Greece columns, with purple and white flowers, it could also be grown as an specimen plant in another garden location use for just specimen plantings. It's height is about 4 feet tall and should be spaced about 2 and half feet from each other at the time of planting. The seeds can be sown under glass in spring to be divided later when the overpopulation is obvious.

Agapanthus, some what shorter plant more like a bush, it will need mulching during winter, and it bears blue colored blooms. The higher reaches to 2 and half feet tall and can be an excellent plant to succeed a tall plant like Acanthus in a border. Alchemila is an even shorter little bush, excellent to use in continuation in a garden border, it bear little tiny yellow flowers and has a beautifully shaped leaf formation, one and half foot long can be raise from seed in spring, the flower stems are widely use in flower arrangements.

As you go along planting your garden border, remember to plant some of the herbaceous plants that wont die during winter for a longer border display, as mentioned before, Brunnera is one of those plants that have long-lived seasons, it reaches about a foot long, and displays little blue flowers with speckled green/white leafs.

A Beginners Guide to Caring for Perennials

Perennials include all those flowering plants that bloom year after year (with care) such as chrysanthemums, marguerites, or daylilies. Some perennials grow, bloom, and then die back to ground level each year, while others are evergreen and produce new foliage even when they are not blooming. Whatever their growth habit, perennials require some grooming during the year to keep them healthy and good looking. Some may need dividing or transplanting when they begin to look crowded.

Follow these four basic care techniques: Shear dead flowers from plants (like dianthus or marguerites) when the bloom season is nearly over. Cut back or remove woody or dying parts of plants (like geraniums or chrysanthemums). Tip cut to produce new sturdy young plants from old plants (like alyssum or sedums). Break up or divide to renew crowded masses of daylilies, coral bells, or Shasta daisies.

Cutting Back - On some plants the flower stalks can be cut back to a main stem or to ground level right after blooming. This works best with plants like aster, chrysanthemum, delphinium, foxglove, gaillardia, gloriosa daisy, hellebore, iberis, penstemon, phlox, Sedum, and yarrow.

For geraniums and pelargoniums, cut woody stalks back to a bud or sideshoot. Plants that produce new shoots from underground (like asparagus fern, fibrous-rooted begonia, or plumbago) can be cut back to ground level.

For polyantha primroses, cut off the top half of the old leaves after bloom to force a second bloom period.

Shearing - Use hedge shears or grass clippers to cut off faded blooms and not more than an inch of foliage. Leave as much leaf surface as possible since the plants may not sprout new growth from bare twigs. Shear such plants as alyssum, chamomile, dianthus, gazania, marguerite, phlox, rosemary, thyme, or any other evergreen with dense bloom.

Tip Cutting - Many perennials quickly form new roots if you break off healthy shoots and stick the broken end into moist sand or prepared sand and soil mix. Some perennials that root easily are alyssum, arabis, aubrieta, bergenia, chrysanthemum, delphinium, dianthus, geranium, iberis, pelargonium, and sedum.

Remove healthy shoots from crowded arabis. Have new pot filled with soil mix ready for cutting.

Poke a hole in soil mix large enough for each cutting. Once in place, gently firm soil around each cutting.

Remove plants when they have grown 2 inches. Replant to large container.

Dividing - Some perennials form a dense clump with old growth at the center and young shoots around the edge. You can pry some clumps apart with spading forks, cut them with a knife or hatchet, or dig them up and break off the young outside pieces for replanting, then discard the old center piece.

Plants that can be pried into sections are acanthus, agapanthus, daylily, and kniphofia [called 'red hot poker'). Plants with dense roots that need cutting apart are asparagus fern, columbine, iberis, Shasta daisy, and yarrow. Pull off rooted outside pieces of coral bells, chrysanthemum, and primrose for replanting and discard the woody center.

Perennials in the Garden

Perennials are plants that reach maturity for at least two seasons. Planting can be grouped as a single, solitary plants in flower beds or border or among shrubs. Many are also planted with annuals and biennials in mixed garden plants beds.Perennials flowers blooming for two years or more to live as mature plants and mature each year. Perennials are probably the most diverse group of plants to show a great variety of forms,Shapes, colors, textures and aromas that their choice for planting and design of the surface, where they want to identify the plants.

Perennial 'leaves can be a very colorful contrast between the dominant vegetation around the plants that form the structural stress from other plants. One possible choice is a great example, dark green acanthus leaves, red leaves of some hybrid Khan, colorful foliage or silvery leaves Onoporduma host species (decorative thistle), Stachys or Senecio. SomePerennial unusual shapes, textures, leaves or flowers can be used as an element that will attract attention, as the parent in a particular part of the garden.

Similarly, perennial flowers are highly variable in color, shape, size and shape, so that gardeners the infinite possibilities of contrasting, complementary or mono-crop cultivation. Even good grouping of perennials are blooming flowers can be interesting shapes and structures, such as whiteflies, horizontal Flowers of yarrow (Achillea), and high, Lupinus has petals.

Popular fragrant perennials are also an essential element of the garden, bees and butterflies, including species such as some species of clematis, daylilies, Nicotiana, Pennant and verbena attracts. However, many perennials will remain attractive in autumn and winter. For example, plant Sedum spectabile, also known as the ice plant that blooms in summer a beautiful red flowers of crops in the thyroid> Flowers in winter remains attractive because it is their flower stems and pods. Flowerbed planted perennials usually contain plants that bloom in spring, summer and those that bloom in autumn.

The floral borders are now planted with many plants in general, but carefully selected by the color of the flowers and leaves, and according to their texture and composition. At the same time, some gardeners prefer to plant in rows according to height, so thatthe lowest plant is later. Perennials planted in the ground are always prepared with care, digging deep and clean from weeds because the plants will grow on you a number of years. The shrubs are usually planted in spring or autumn. Shrubs should be watered no adult with the same frequency, except during periods of drought. Perennials are sensitive to low temperatures in winter.
