Working in small sections, place the larger pieces of flagstone and tap them in place with the rubber mallet so they won't wobble. Pack sand around the edges to secure the flagstones. Also use the mallet to break slabs into the sizes or shapes you need (figure H). Don't try to smooth out the edges--rough edges are what give flagstone its character. If you plan to add groundcover later, leave a couple of inches between stones. Figure I shows the flagstones in place.Henricks picked black Mexican pebbles for the border between the brick path and flagstone terrace. She uses three bags for this project at a cost of $10/bag. The dark coloring contrasts well between the reddish bricks and rosa flagstone. There are many varieties available--use whatever looks best in your design. Simply lay out a single layer of the pebble in the gap.
After the pebbles are in place, Henricks plants groundcover in the gaps between flagstones. To complete the project, she places a bench and containers on the terrace to give it a welcoming feel.
Planting: A Garden Terrace
Henricks says that because the terrace and pathway are part of the entryway to the house, they need more color to make them welcoming. She incorporates greenery between the flagstone and bricks to soften the edges, colorful containers of woodland plants on the terrace and flowering vines on the fence. Groundcover in the gaps between the flagstone make the terrace look like it has been part of the garden for a long time. Her landscape design includes:
Japanese maple (Acer palmatum 'Ever Red'), Zones 6-8, features a classic, graceful form and colorful leaves year-round.
Bacopa 'White Lace' (Sutera hybrida), Zones 9-10, thrives in woodsy, partially shaded settings.
Baby tears (Soleirolia soleirolii), Zones 10-11, is planted between the flagstones
