Culture
Easily grown in average, dry to medium moisture, well-drained soils in full sun. Does very well in gritty, sandy loams. Good heat and drought tolerance. Best to shear plants back regularly before flowering to keep the planting tidy and to promote new growth.
Noteworthy Characteristics
Origanum is a genus of about 20 species of herbaceous perennials and deciduous and evergreen sub-shrubs. They are native to the Mediterranean and southwestern Asia. Some are used as culinary herbs.
Genus name probably comes from the Greek words oros meaning "mountain" and gamos meaning "beauty" in reference to the physical appearance of this plant which is sometimes native of mountain areas where it is appropriately referred to as "beauty of the mountain".
'Drops of Jupiter' is a hybrid, ornamental oregano selection that features fragrant, chartreuse-yellow foliage and dense, terminal clusters of blooms. Mature plants will reach up to 2' tall and spread to fill a 3' area. The small, fragrant, pink flowers are surrounded by persistent, dark purple sepals and bloom from mid-summer to early fall. Although the leaves are edible, they are not as intensely flavored as oreganos bred specifically for culinary use.
Problems
No serious insect or disease problems. Root rot may occur in wet, poorly drained soils. Fungal diseases, aphids and spider mites are occasional problems. Deer and rabbits tend to avoid this plant.
Uses
Mass in border fronts, herb gardens or rock gardens. Also effective as an edger. Large containers.
