Got a Wet Spot? Grow Bog Rosemary

Written by Mindy on June 30th, 2013

Do you have a spot in your landscape that stays wet?  Or are you looking for a plant that is low mainentace and looks good?   Well if either one these situations apply to your garden space, then I have the plant for you.

Bog rosemary is a wonderful evergreen shrub that is powdery blue in color year round.  In the spring, urn-shaped white flowers with a tinge of pick appear.   The needle like leaves along with its multi-branched nature allows this plant to standout especially in monochromatic landscapes.

When you plan to use this plant, study the area carefully.  Bog rosemary does wonderful in bogs, swamps, and alongside ponds.  It can even tolerate some standing water.  While this plant is flexible in its moisture requirement, it is inflexible in its pH requirement.  Bog rosemary requires a soil pH on the acidic side.  Once you have the plant in the ground, if the leaves begin to yellow this is an indication that the soil is not acidic enough.  If this is the case, mulch the area with pine needles.

When planting in urban environments, monitor the leaf health.  While this plant can tolerate some urban pollination, planting in highly polluted areas can be detrimental to the plant.  If you notice the leaves changing colors, consider planting in a different location.

When planting your bog rosemary, make sure to dig the hole at least twice the width and height of the container it has come in.  If you are dealing with clay soils, do not forget to scrap the sides to prevent glazing before moving on to the next step.

After the hole has been dug, mix in peat moss into the soil removed and place 2 to 3 inches back into the hole.  Once that is done, remove the plant from its container and place in the hole.   Test the height of the plant.  If the plant sits below soil level, add additional soil.  If the plant is level with the surrounding soil, then continue with the planting process by filling in.

Once the plant is in the hole, gently tap down and water in.  Add an organic mulch to the top to increase acidity of the soil and control weeds.

Bog rosemary spreads by rhizomes so plant in areas that have ample space for this type of growth habit.

One cautionary tale of this plant is the fact that it is not edible.  While the name implies a culinary aspect, this only comes from the leaf shape and ever part of the plant is poisonous, so handle with caution.
