We went to Shannon Florist and Greenhouse for sea grass. We wanted something modern looking and dense to provide screen between our garden and our neighbors.
Instead, we ended up with three small lilacs (Bloomerang Purple, Syringa Penda) for the front of our garden. We added woolly, silver licorice plant (Helichrysumn petiloare) to fill in at the base of the lilacs and spill down the side of these tall containers. Had to drag six more big bags of soil up for these planters.
