MOD EL GARD EN

In our model garden in Wassenaar, we test all perennial plants

extensively before using them in practical applications.

p e r e n n i a l p l a n t s i n p u b l i c g r e e n s p a c e s

As of 2017, GreentoColour® boasts a history of about 13 years and has

fulfilled its original mission: to restore perennial plants to public spaces.

In the meantime, we have executed more than 2,300 projects with

perennial plants.

The following pages provide an explanation of the GreentoColour®

concept. This concept has proven its value by using a comprehensive

approach. The choice of plants, groundwork, quality of the plants, and

the way they are tended are all equally crucial to success.

That is why you will not find a 'plant list' or 'best varieties', because

merely choosing the right variety does not guarantee successful planting

if, for example, the groundwork has not been done properly. Fortunately,

more and more clients are now starting to adopt this point of view.

While driving past some projects we executed with a client, he gave us

one of our favourite compliments: "the reality is even more beautiful than

the pictures". Perhaps you could try to see the following pages through

his eyes.

With kind regards,

THE CONCEPT

g r e e n t o c o l o u r

Choosing GreentoColour® means to choose colour, flair, biodiversity and dense covering in public spaces, all achieved within one year.

GreentoColour® is based on the cost of management. To keep maintenance easy, we do not use mixtures or open-space landscaping.

Perennial plants must comply with 21 conditions in order to be included in our range. GreentoColour® takes landscaping to the highest possible

level, while keeping operating costs low compared with grass or traditional shrub plantation, due to low maintenance levels. Beautiful wintery

landscapes, enormous biodiversity and the plants' very long lifespan are just the icing on the cake.

In order to live up to this guaranteed promise, GreentoColour® applies a unique formula that is based on 4 pillars: the right plant in the right place, soil preparation, the use of 8 plants of P11 quality per m² and a

maintenance plan, an important part of which is short-mowing/mulching/fertilising in March.

Choose GreentoColour® to achieve a densely covered, colourful result with perennial plants in public spaces within a year.

Be inspired by the unedited pictures in this brochure and at www.greentocolour.com.

1 THE R IGHT PL A NT IN THE R IGHT PL ACE

A tailored planting plan is made for each location and situation. Using a range of

perennial plants in compliance with our 21 conditions.

N EP ETA

With several varieties of Nepeta – there are three new varieties – weed growth can be quickly and effectively suppressed. Suitable

for dry places.

GERANIUM

The nursery carries 45 varieties in its assortment. Only 10 of these are used for GreentoColour®: only those

that provide proper soil cover and remain permanently healthy.

HE ME R OCALL IS

There are 20 types available within GreentoColour®. Hemerocallis is a favourite

in warm spots where road salt is used.

PERS ICARIA

A nearly perfect plant where high and fast covering is required.

Known for its red colour, but also very decorative in

white and pink.

GRASSES

GreentoColour® uses grasses rather sparingly, for the

simple reason that although they initially often conform to the desired plan, in later

years they often grow so big that they can dominate the entire appearance of a plot. In addition, dense covering

and ornamental value are not without problems for certain

times of year.

2 S O IL PR E PA R AT ION

Our special GreentoColour® soil improvers (100% organic) provide the optimal soil for a quick start, so

that plants quickly achieve dense covering.

is 110% of the result.


191818 19

MANUAL PL ANT ING

Walking on loose soil is avoided as much as possible to keep the soil loose.

3 US E OF E IGHT PL ANTS IN

P 1 1 QUAL ITY PE R M 2

Quick results are achieved by planting eight units of heavy P11-quality perennial

plants per m 2. Because the large root balls contain significant nutritional and moisture

reserves, teething problems are prevented and watering is virtually unnecessary.

By cutting extremely short with a flail mower every March, nutrients can remain in nature and the

plantation has a life span of several decades.

HOEIN G IS AL L OW ED !

Hoeing with a narrow hoe is quick and easy in the first part of the season. Root

weeds are best removed by hand. Ask Griffioen for the "weed card", to know

the difference between seed weeds, root weeds and perennial plants.

KEEPING TH INGS T IDY , RATHER THAN CLEANING

Immediately after planting and during spring, weeds have a chance against perennial plants. If frequent,

short maintenance is carried out during this period, overall maintenance pressure will be minimal.

FIVE BENEFITS


In addition to a spectacular appearance, each GreentoColour® project has the following advantages:

1 FULL DENS ITY GROWTH

1 FULL DE NS E COVE R ING

Very fast dense covering results in significantly less weed growth and litter compared with

shrub plantation.

2 QUICK RESULTS

Virtually complete covering after the first full summer. This is achieved by using heavy-quality plants in the

right location with the right soil.

Thanks to the visibly dense planting, access is minimised.

5 LOW MA INTE NA NCE A ND LONG S E RVICE L IFE

Maintenance, including annual fertilising, mowing, and mulching in March, ensures

plants have a long service life. As a consequence, the perennial plants renew themselves each year and do not have to

be removed. In addition, mulching makes them fuller and the crop remains about 30%

lower, which also makes it firmer.


3434

ATTR ACT IVE Y E AR R OUND

Because mowing takes place as late as March, the GreentoColour®

plants are a pleasure to behold year round, and offer a

constantly varying appearance.
