Answer: Begonias can just disappear if the soil remains too wet, which seems to be what has happened to yours. Instead of begonias, try planting Bishop's hat, or barrenwort (Epimedium x versicolor): Attractive heart-shaped leaves. With its delicate yellow flowers, 'Sulphureum' is the most popular cultivar.
Dead nettle (Lamium maculatum): Look for cultivars such as 'Beacon Silver' with rosy pink flowers and silver leaves edged in green or the white-blooming 'White Nancy'.
Heart-leaved bergenia (Bergenia cordifolia): Large, leathery leaves and rose-pink flowers in early spring?looks great in a big grouping.
Sweet woodruff (Gallium odoratum): Finely textured leaves and white flowers in spring?top-flight ground cover in the shade garden. Will spread.
Dicentra (bleeding heart) is another good choice.
Hope one of these suggestions is just right for your garden.
