The outskirts of your large water garden, the small water garden that is
shallow, and the areas of your landscape that never seem to dry up are great
places where shallow water marginal plants can grow. Variety in your gardens
will be needed when you have gardening in larger areas that differ from dry hard
soil to the wet and swampy Ė use these plants in areas of your landscape or in
the water garden where the water levels are from one inch to five inches deep
for great success.

your water garden. Even the stems and roots of this plant are very distinct in
their smells that are given off when cut open. This plant will grow to be any
where from six inches high to a little over a foot high. Over the years, your
Houttuynia can grow to be close to a foot and a half high but this can take a
few years. This plant will grow well in the very shallow areas of your water
garden, up to about two inches of water at the most, living in full sun or in
the partially shaded areas.

forty inches tall. You can grow the water iris in soil that is moist all the

Skunk cabbage is a shallow water marginal that has a very sophisticated look to
it. Skunk cabbage grows with either a white or a yellow flower on the thick stem
of this plant. The flowers will appear in the early spring to the mid summer
months giving you great shows. Because the leaves are broad on the skunk
cabbage, they are great border flowers for the water garden where you donít want
people to have access to the water garden. Skunk cabbage will grow to be about
four foot high when they are mature. Seeds will dry over the latter parts of
summer, and you can replant these seeds for new skunk cabbage plants. These
plants will grow in both the full sun and in the partial shade areas.
