6 Knot Garden Plants
A knot garden has landscaping plants laid out in geometric, intersecting shapes to create a living Celtic knot. Plants with varying colors of foliage, as well as similar sizes and soil requirements, will create the most effective knot garden.
While traditionally composed with herbs, a knot garden can also use low flowering plants to create a lovely effect. Most Celtic knots consist of three individual strands, so here are six of the best plants to include in your knot garden.
Herbal Knot Garden
For an herbal Celtic knot garden, plant 3 herbs, such as tricolor sage, winter savory and rosemary. All three of these herbs thrive in hardiness zones 7 to 10.
Floral Knot Garden
For a floral knot garden, these three garden plants will do well together: lavender (in Hidcote or Munstead variety), wall germander and barberry (in Crimson Pygmy variety). These three are suited to planting zones 5 to 9.
Other Tips for Your Knot Garden
You may combine herbs and low plants of similar size for a mixed garden.
Note that knot gardens require a location with well-drained soil, open space and lots of sunshine to grow thickly into the knot shapes. Add colored pebbles or crushed stone as the mulch to highlight the knot design.
