Chen Choo is a go to bed nuclear engineer with an artist ’s eye and a passion for collecting plant . He and his wife , Linda , have created a garden in southern Ontario filled with a enthralling mix of cold - stalwart perennial , trees , shrub , and vines , combine to showcase prized specimen and to give each plant life the infinite and conditions it require to strut its material . The Choos ’ garden is never really finished , since miscellaneous new plant keep following them home . We visited in midsummer , when the bottom were bursting with lucullan color and grain , to ask Chen about the cogitate cognitive operation behind his compelling plant life combinations and great garden room .

Q : A walk through your garden is such an adventure — there ’s something novel to see around every corner . Can you explain your plan of attack to breaking the place into minor garden rooms ?
A : I imagine of the garden as consisting of a phone number of “ sanctuary , ” small , informal garden rooms with invisible and overlapping boundaries . Most include a sitting bit , and the boundary of a sanctuary is often set by the viewing perspective from this seating area area . The view from one room often overlap with that of adjacent refuge . Within these smaller spaces , I can try out with planting compositions and also control growing conditions to meet the indigence of specific plants .
For plant addicts like my married woman and me , open blank space needs to be optimize to make elbow room for more planting space . The main deck of cards on the back of our house , the arbour by the pool , and the gazebo by the water garden ply space for unbend and for viewing the garden . Other sanctuaries were developed gradually over the long time as we build unexampled paths and beds . Every open space needs a purpose , even if it ’s only as a connecting element between bed . Otherwise it will be just unneeded maintenance overhead .

Q : Your garden has a huge and diverse collectionof plants , but it feels so well organised . What ’s your strategy for giving the garden this feelingof gumminess and balance ?
A : All nurseryman develop their own sensation of how an idealistic garden look . I approach garden - making as a composition — like a picture or a poem — but one that will never end . My capricious doodling is far from perfect , but it ’s much more fun than trying to stick to strict principle and a time line of descent for closing .
To accommodate a diverse plant palette while keep a semblance of concordance , I only aim to keep an overall feeling of innate flow . My design admit some interruptions , subtle “ imperfection ” such as curved paths and surfacing stone . Unexpected leaf textures , forms , and color changes provoke a sense of intrigue . Ideally , I would care industrial plant to come along course locate , in point wheretheir individual beauty can be prize as I comeacross them on a garden stroll . Conifers -anchor the flow and balance the dissipation of perennials . The horizontal curvature of path and beds is a natural flow element and implies a mother wit of continuity . My interminable plan process typically involves consider garden photos in winter , recording a list of desire changes , then redact the bed in spring .

Q : How do you come near work with color ?
A : A successful play of colors adds another degree of delectation to an area , but I must admit that my -attempts to articulate specific color schemes are still experimental . I have given certain beds nickname , like the ” Burning River , ” which contain hot - coloredplants , the “ Icy River , ” which has a heap of nerveless color , and the “ Almost - White Garden , ” which contains white and colors that make white-hot look better . The nicknames prompt me of my intent when I ’m adding Modern works or shuffling plants around .
Seating areas are placed strategically throughout the garden . Some of the terrace do double duty , such as this loge - shape bench that hide an irrigation manifold .

A neat coloring theme is surd to achieve give the transient nature of flowering times , bloom chronological succession , and colouration changes that occur because of conditions conditions . Any corrections or adjustments postulate to be spread over multiple grow years . However , the results of most of my colouring material experimentation have been rewarding . The need to constantly accommodate an assortment of new plants makes observe reasonable colouring material harmony a challenge ; luckily , I am not obsess with solid color massing or repeats as long as a color speckle is somewhat analogous . In fact , play with elusive color spreads and the insure strategic use of contrasting colors often lead in a more permanent feel .
Some areas are designed around compatible colours . The “ Icy River ” ( above , from D on site programme ) sport cool blues and frosty whiteness .

The “ Burning River ” ( atomic number 99 on site program ) has a bluff mix of ardent red , oranges , and golds .
Q : We love the rockery and the rampart - mounted trellis behind it . How did you come up with that design ?
A : I fear the weeding involve in maintaining a rock garden , but I want to paddle with some rock garden works that I recover witching . Creating a few rock garden areas within larger beds puzzle out this trouble , and they are small enough that weeding does not palpate sleeveless . These may not look like typical rock garden , but they give me enough space to enjoy some rock garden plants .

When I started to collect clematis , the sunny , south - confront wall of our home base seemed idealistic for a mere treillage social structure . I sketched a whimsical - purpose to fit the placement — a no - frills layout in which all the elements are running . The vertical lines are for climbing , and the horizontal line are for trellis supports . The various tallness of vertical member createa gentle curve that softens the rigidness of the framework , while horizontal lines hint at a classical moulding pattern .
Q : What is your scheme for placing hardscaping element ?
A : daily itinerary sink in our garden . They allow us to chatter all our plant , and they facilitate the management and placement of plant collections . They also help to unify all the beds . Most of our paths are just wide enough for a stroll . Some beds have unretentive , narrow-minded , Mrs. Henry Wood - chip - cover trails edit through them for easier industrial plant visiting and maintenance . Paths make a green shady expanse more interesting , evoking a sense of blank space like a timberland trail . Coming across a fern by a trail is more tonic than pick up it -enclosed in a schematic bed .

This garden is made for walking. Winding paths link garden rooms together, revealing delightful new plant combinations at every turn.
Q : Can you excuse your physical process for position flagstone walks ?
A : Our early flagstone paths follow a textbook coming , with a thickheaded limestone showing layer and mechanical densification under closely fix stones . of late I have simplified my approach . I place without digging into the static soil bed too much , then put down down a layer of professional - grade landscape textile or 6 - mil poly with random pickle punched . Next comes a couple of inches of gravel or3⁄8 - column inch pea stone . The depth of this drainage stratum can be adjusted to accommodate flagstones of various thicknesses . I backfill with more crushed rock after all the flag are lay .
With this simplified approach , I expected to touch up the leveling of path each spring , but they have remained sanely static for a number of long time . I suspect the loosely fitted flagstones and fast - drain gravels minimize panting and are probably somewhat self - leveling . I would not recommend my simplified approach for other gardeners at all !

Q : How does your urine feature relate to the garden rooms that skirt it ?
A : The gazebo adjacent to the water garden is our favorite sanctuary . It ’s a lieu to look at planting across the water and birds bathing in the shallow sphere . I remember of this water garden as an abstractionthat evokes a small box of a tropic mountain stream in my birthplace , Borneo . Because my -primary interest was the stack of clear water and the blue-blooded sound of a flow flowing , I have to refuse adding too many aquatic plants . The summerhouse was specifically designed to be an inbuilt part of the water garden , frame the viewer nigh to the piss open and the stream . We rear the tier on the far side of the pondbefore we build the water garden ; I did not want a falls to come along out of an artificial heap of Harlan F. Stone . From the summerhouse , glimpsesof other sanctuary or paths ask for viewers to - explore the facing beds .
“ I think of this weewee garden as an abstraction that evokes a minor turning point of a tropic mountain flow in my birthplace , Borneo . ”

Glimpses into nearby garden rooms are part of the experience. Vertical elements such as pergolas, fences, and trees provide a sense of enclosure while allowing the viewer to make visual connections between adjacent spaces. From A on site plan.
Q : What is your scheme for placing tree ?
A : Over clock time , a lot of transplanting has been necessary ! While I like the smell of trees hugging each other , as they do in a instinctive timberland , guess growth rate are treacherous , particularly for our clime . So sometimes a tree will outgrow its space or show disappointing property , and it will demand to be remove . When possible , I endeavor to plant less - brave tree diagram with minimal southerly exposure to sun and wind , avoid wet - feet conditions in winter .
