If the soil in your garden is already sandy, work in some bark to add porosity and compost to help retain moisture. Mulch helps moderate soil temperatures, preserve soil moisture and discourage weeds. Mulch also provides vital winter protection. Apply a high-nitrogen fertilizer in spring as plants begin to emerge. These are a possibility for those who have had no luck with hostas.
Peacocks produce lavender summer blooms.
Alpinias, or shell gingers, are increasingly familiar in area gardens. These tall perennials are tough, will take more sun than some gingers and are drought-tolerant once established. The shell-like blooms appear in spring and summer following winters without freezes. There are several Hedychium species at Mercer, in addition to the ever-popular and highly fragrant white butterfly ginger, which merits experimentation in home gardens. Relatives include the bottlebrushes with large spikes of smaller, spidery flowers in various colors.
