Leaf Structure
Show Feature
Concept:
The design is based upon this leaf section diagram with adaptations to allow greater
visitor access , interpret and interaction with the space and features.

Track way (not to scale) included to demonstrate orientation
Epidermal
The Epidermal layer devoid of chloroplasts is
being created using dark burgundy coloured
themes planting in a mixed band at ground
level. This will be created through matrix
planting of edible plants and possibly the
addition of a bronze Heuchera to add mass.
Additionally on the lower section of the leaf
there will be 3D stoma structures created
using lengths of acrylic piping.
To add a strong vertical element the lower
epidermis layer will have
The entrance vertical wall (1200mm
wide and 1800mm high) positioned
on the right of the entrance to
provide definition. A similar panel
will be on the reverse face of the
waxy cuticle on the upper leaf.
Planted entirely in bronze foliage
with interspersed panels of visitor
information.
Stoma (will be bronze)
Spongy Mesophyll Layer
This walk through area will be formed by
mound forming groups of plants and
aggregates and sculptural features.
This layer has been attacked by a leaf
miner…follow its trail of destruction
through this area with desiccated cells
as a walk through element and we are
looking to create a tail and head section
of a miner to be entering and emerging
from the desiccated area.
Main pathways on existing turf unless
sponsor for green mulch material and
geotextile are available.
A vertical panel will be positioned on the reverse of the entrance epidermal
layer. This will include info on the process of Photosynthesis.
See separate CAD drawings of sections of these panels (1200 wide and 18002400 high). These will consist of 3D planted hemispheres, acrylic
hemispheres with interpretation literature on planting and materials and
coloured acrylic disks giving bold colouration.
Planting zones in forms of cells will include pollinator friendly plants; energy
sources; edibles and medicinal plants.
Phloem Tissue
Groups of phloem vessels as vertical
sculptural structures created from sugar
laden drinks cans/ bottles encircle the
water feature xylem feature. These
phloem will vary in length as a cross
section in 3D to allow clear views of the
xylem.
Xylem Tissue
Vertical sculptural Water Feature made
from Plastic bottles/ pipes/ filter
materials. (Design still in progress)
Palisade Cells
These will be large cloche like 3D structures polythene structures
approximately 900mm high. These rod shaped cells will be filled with
photosynthesising green plants predominantly salad leaf crops to represent
the crops produced under glass.

Waxy Cuticle
The waxy cuticle layer will be fabricated from a wall
of glass bottles which have scope to include panels of
LED lighting. These will be outward facing on the
back boundary to a height of 1800 mm on the right
hand back section to create a vista of height layers
and screening. There will be lower level sections
running along the back boundary of the feature to
define the enclosure.
The inner layer of epidermal tissue will be
represented by a backing of the gridded Epidermal
panel (allowing for further interpretation materials
and vertical planting.) The Epidermal planting will be
a repetition of the previous planting.

Aphid Attack!
Attack of the giant aphid … inspired
by Eden’s giant bee this 3D sculpture
will dwarf visitors as it sits adjacent
to the back of the garden it will be
positioned to be in line with the
entrance pathway for photo
opportunities.
There will be interpretation
materials attached to its body
panels.
