Bloom time: Spring through fall
Leaves: Serrated grey-green, medium size leaves
Pests and Disease Problems:
Deer and goat resistant, virtually disease and pest free. Fungal problems may arise when soil remains wet over extended periods of time.
Growing in North Texas
Prefers well drained soil, full sun and is drought tolerant once established. Water regularly until established, then once a week through the height of summer if weekly rainfall is less than one inch. The plant is low maintenance although deadheading spent blooms will help produce more flowers. A general fertilizer in spring and summer will produce more flowers, but this activity is not at all required if soil has good fertility. Maintain two inches of mulch. Cut to ground after first frost and mulch over for winter. The plant will reseed itself after established and seedlings are easily transplanted to other areas in the garden.
The Henry Duelberg Salvia was discovered by Texas horticulturist Greg Grant in a Central Texas cemetery on the gravesite of Henry Duelberg. Mr. Grant also discovered and named the white flowered Augusta Duelberg salvia he found nearby on Augusta Duelberg’s gravesite. These two salvias make a pretty pairing when grown next to or mixed together.
