Brunnera - This is a very attractive shade garden perennial that can become a groundcover. Somewhat heart shaped fuzzy leaves and vivid light blue flowers in mid spring. Prefers loose, moist, well drained soil. Protect from the hottest afternoon sun and increase your watering when temps exceed 90°. Deer resistant.
B. macrophylla - Light blue flowers in early April, evergreen to 12" tall.
B. macrophylla ‘variegata’ - Just like the species except the foliage has a thin, irregular white border. Has a tendency to revert back to green which should be removed.
