I had a poor drainage area on the side of a driveway, and was able to create
rain garden in very little time and
with very little effort. My favorite way to do things..
Louisiana Iris - great for bogs and poor drainage areas
photo shows the area on the right where this garden was installed.
Sweet Flag starts out a
bright green, then turns green with gold edges as it matures.
It stays evergreen (the garden was in USDA http://zone 8). It has a very "earthy" herbal
Tops at 12"wx12" high when mature. Likes wet feet, can even grow
immersed in water. Handles
drought, and has no pest problems (except for rabbits and i can't say that i
They are mounded and
dont' need trimming. Very beautiful when the wind blows,
they add movement to your landscape. It can take sun and
some shade - i'm going to use it in the
foreground of a lot of my plantings. It would make a fabulous lawn replacement
Below are plants purchased in 1 gall. pots, about 6" high. the sticks mark
Louisiana Iris and Japanese Iris bulbs. Reminder: do not plant irises deep.
Most of my success with irises (photos of my beauties will be posted on this
is from planting with the top third of the bulb exposed, and ignoring them.
**They're also a xeriscape star - i haven't watered any variety of my irises in
Here is the new rain garden. It
needs no attention or maintenance
Apparently, the weeds in the photo have been eliminated at the driveway edge.
The area next to my
driveway, the right of way between houses that also leads
me to my backyard gets water-logged after every rainy day. The area is not
for anything. I didn't want to
invest in a french drain or new sump pump system
if i could use the area as a garden
The only water the garden
gets is from the rain. Plants chosen were especially suited to the
environment they're in, my planting zones, and my needs - My gardens
need to be
self-sufficient, insect- and drought-resistant, resistant to animals whenever
I chose marginal pond plants, bog plants and flowering perennials that like wet
or dry feet.
The bog plants had to also
deal with occasional drying out and not need to be always
moist or wet. I used non-invasive Louisiana Irises, dwarf irises, japanese
Rosa Rugosa, Sweet Flag grasses I covered the top with a layer of pea gravel -
very pretty when water sits on top. The birds and dragonflies love it there.
Note: You can create rain
gardens in multiple planting zones with many of the same plants.
Low maintenance, colorful
and fragrant. The areas around the new garden are less
saturated, there's less runoff from the driveway into the stormwater
No chemical fertilizer needed, no insects except butterflies and dragonflies. I added epsom salts to
growing area after i dug out the garden to give them a "green" boost,
and about once a month under each
plant. Location of your garden:
anywhere rain puddles and runoff hang around for a few days
How I Created My Rain
Note:Never dig or use
earth-moving machinery without checking with the utility
commission to come out and mark your property for power lines, etc. it's free!
The hardest part is
removing all of the grass and weeds from the already soggy
area, and digging the holes for the plants. I dug out all the grass carefully by hand,
utility lines are buried in that side of my front yard, and i'm never feeling
Arrange to have your utility companies flag where lines are burie before using a
shovel. It's free.
To find plants suitable for a rain garden, do a search online for "marginal
pond plants" or
"bog plants". Always ascertain that you're not using an invasive pond
or marsh plant.
The "wildly" popular but very invasive Louisiana Yellow Flag Iris is being
promoted in certain zones
as a good bog garden plant - do NOT use this if you are planting near a neighbor
or in your front yard.
This wonderful site has a
listing of invasive plants. I admit that I have successfully used some plants
invasives in other parts of the country for covering large, wild
areas where spreading is not a concern.

Center listing of invasive plants
Remove all the sod, grass,
outline your garden with stones,
or edging if you wish, but remember to leave an
where the water naturally flowed in to create the wet areas in the first place.!
I outlined the back of mine with
brick edging left around the property. Recycle landscape materials when you can.
My edging is movable - as i
expand the water garden, i'll move the brick pavers out a little more.
I'll be adding sculptures and rock features as i go along.
Once the grass is
eliminated, dig the center of the garden a little deeper than the outer edges.
Dig out deeper
areas with your trowel or shovel in various areas of your garden to create
valleys where water will pool more.
Make sure that wherever the water runoff is coming from that originally started
you on this project can still
run into the garden - you can dig a little bit of a downward slant from the
source of the runoff to the rain garden.
I added pea gravel to the
top to eventually blend in with the other gardens
i've started and to add a bit of a serene and clean feel to the water area.
