Geranium 'Old Scarlet Unique' - S1

Geranium 'Old Scarlet Unique'

Pelargonium fulgidum hyb.
This heirloom early summer-blooming geranium boasts large clustered flowers with a brushmark of black at their centers, offering an eye-catching contrast to the lovely, warm red hue. The cut-edged leaves are soft to the touch and cloaked with hairs that turn the foliage a sage green color. They grow relatively large and are at their showy best when trimmed to shape.

Geraniums traveled from South Africa and were cultivated and marveled over in early glasshouses of the 1600s, and we love them still for their varied beautiful leaves and flower colors. Provide well-drained soils and allow the soil to dry before watering thoroughly. Deadhead spent flowers regularly and provide some afternoon shade in hot summer areas, for they do best in low humidity, cool to moderate summer areas. 'Old Scarlet Unique' blooms better than regal types in the often hot and dry weather of summer. Trim to shape right after bloom ends in summer and leave potted plants outdoors until temperatures drop into the 40-45F range, hopefully exposing them to six weeks of cool night temperatures. Bring them into a cool room, around 60F, to overwinter, and their gorgeous blooms will start to unfold in late winter.
Final Spacing:
Water Requirements:
Low Water Use
Watering Details:
Water when soil is dry 2" down into pot. Geraniums suffer if the soil stays saturated with water, so water only after soil has dried.
Soil pH:
Prefers neutral.
Fertilize twice a month with a balanced formulation such as 15-15-15.
Diseases & Pests:
Aphids and mealybugs can be troublesome; if detected, treat with an insecticidal soap or neem oil. Avoid botrytis by spacing properly, not wetting the foliage when watering, and keeping dead plant material, such as spent flowers and leaves, cleaned up.
