Contemporary Perennials for the Modern Garden

With Christmas round the corner we want to make sure the garden not only looks beautiful and well stocked for Christmas Day but also that we come back from our holidays to an attractive, relatively weed free garden we can enjoy for the rest of the summer.

In this issue we've focused on doing just this through using modern perennials. Topics covered include

THE MODERN PERENNIAL BORDER

Perennials have been favourites of gardeners for hundreds of years, even as fashions change and we are certainly seeing a mini revival in interest and planting of flowering borders and gardens. They are the mainstay of the summer garden providing a succession of colour for months.

Planting a new perennial border can quickly improve your garden, as the plants are faster growing and softer in form than shrubs. And, because of the way perennials grow, the garden will not stay the same all year round as it will change with the seasons.

Perennials are also great value, forming clumps which can be divided in future years.

I'm enjoying seeing the perennials at the Garden Centre, including many not seen elsewhere these days, coming into flower and providing real interest for our customers.

As we rapidly approach summer, we suggest you start work on your summer borders very soon. Choose a site with the maximum amount of sun and make the border as deep and long as possible to accommodate many different sized plants with a variety of flower shape and plant forms.

We can help you work out the best way of doing this for your conditions, so come in and talk to us if you'd like some help with this.

GOOD PREPARATION

Before you start though, a new garden always benefits from good preparation.

So, dig it over first (one to two spade depths if you can) removing all the weeds, and then dig in lots of organic material. If you have heavy or very sandy soil, incorporate gypsum with the compost and dig in to a depth of 30cm. We've got bags of gypsum in stock and can advise you as to how much you need.

Most perennials enjoy free draining soil so sand or fine gravel could also be added at this time. Finally, fork through Burnet’s Gold Growmore fertiliser.

PLANT SELECTION

Now, start selecting your plants.

For the modern border, look for plants that are bolder and with stronger colour than the dainty 'cottagey' types used in the past. Begin with a few non-perennial plants to give the border structure. Some of our NZ natives are ideal for this such as the smaller varieties of flaxes and the new cordylines – Cordyline ‘Red Fountain’ or Cordyline ‘Cardinal’ or even grasses.

Take a look at tall types of grass like Miscanthus ‘Zebrinus’ or Lomandra longifolia. I would also consider using Muehlenbeckia astonnii for its interesting airy texture.

Then add plants with large leaves - Ligularia ‘Britt Marie Crawford’, L. reniformus, or the very bold Canna ‘Tropicana’.

Weave drifts of your selected perennials between these larger plants. These groupings should be irregular and quite large to give the garden a feeling of movement and look alive, full and lush.

A few things to remember:

• Select plants with different flower forms and shapes. Look for spires (verbascums and foxgloves), globes (alliums & euphorbias), plates (achilleas) and dots (Verbena bonariensis).

• Light coloured flowers will fade into the background so the quantity of these should be greater than the drifts of those with vivid colours.

• If you have a colour clash say red/pink separate them out with a buffer
of grasses or foliage plants like heuchera.

• Use fewer varieties in larger, bolder drifts as this will reduce maintenance.

• Mulch well after planting with Mulchpost - don't forget this helps keep down the weeds and locks in moisture. And of course we've got that deal of three bags for $24.00.

NEW PLANTS

A couple of newly introduced plants have really caught my eye

Buddleja ‘Silver Anniversary’
One of the best looking silver plants we’ve seen for a long time. It is a cross between Buddleja crispa and Buddleja loricata. Its striking silver foliage will look great all summer in any mixed planting in the sun. The clusters of white flowers have a mustard eye, sweet honey scent and are loved by butterflies and bees.

Verbascum ‘Royalty’
One of a new range of compact verbascums growing to 30cm. A very hardy and robust plant for the full sun. It has masses of strong spikes of purple flowers all summer.

Heuchera ‘Lime Rickey’
A lovely contrast plant to light up a shady garden with moisture retentive soil. Leaves emerge chartreuse in spring, but mature to lime green in summer. Tiny, white flowers appear in spires in late spring to early summer on slender stems rising above the foliage mound.

THE KTICHEN GARDEN

There has much information in the media about vegetable gardening. We are seeing the results of it here with lots of new gardeners asking for our advice as well as buying plants and seeds.

Come in and pick up the Kitchen Garden Guide put out by Tui who have also introduced two welcome additions to our range of growing media - a 40ltr bag of Vegetable Mix and 30ltr Tomato Mix. These are specially formulated to give you the best results, particularly useful if you are limited to growing in containers.

To those of you new to vegetable gardening, don’t despair if you haven’t planted your tomatoes yet!

It is still early for planting summer crops, as they need protection from cold winds and the occasional low night temperatures (as experienced last weekend!).

In fact, if you plant runner beans seeds too early they won't germinate in the cold soil but rot instead.

Note, we always get in vegetable seedlings at the time we consider to be the best for planting out - dependent on the weather. For example, we have punnets of Basil this weekend, but we would advise you to keep it inside in pots at the moment.
