GardenAdvice notes
A more ornamental oregano, ‘Margaritha’ is grown for its long display of dainty flowers held among showy, papery pale bracts, which have a hop-like charm and last for weeks. Aromatic and drought-tolerant, it is as pretty in a gravel garden or sunny border as it is attractive to bees, tumbling nicely over the edge of a pot or wall.
Growing & planting
Plant in spring in well-drained soil in full sun — marjorams and oreganos thrive on poor, dry, even limy soils and dislike rich, wet ground. Ideal for gravel, sunny borders, edging and containers. Space about 30cm apart.
Care & maintenance
Low-maintenance. Trim over after flowering to keep it neat and encourage fresh growth. Water only while establishing; thereafter it is drought-tolerant. Keep it on the dry side, especially over winter, to avoid rot. Divide congested clumps in spring.
Propagation
- Division: Lift and divide clumps in spring.
- Cuttings: Take softwood cuttings in early summer.
Pests & diseases
Generally trouble-free in a sunny, well-drained spot. Its main enemy is winter wet, which causes rot. Otherwise little troubled by pests or disease.
Uses in the garden
Superb for gravel and Mediterranean-style gardens, sunny borders, edging, herb gardens and containers, where the aromatic foliage and bee-friendly flowers earn their place.
Wildlife value
Marjoram and oregano are among the very best plants for pollinators: the summer flowers are hugely attractive to bees, butterflies and hoverflies, and are a magnet for beneficial insects.
Toxicity & safety
This herb is generally regarded as non-toxic to people and pets.
GardenAdvice tip
‘Margaritha’ blurs the line between herb and ornamental — its showy, papery bracts and long flowering make it a lovely thing for a gravel garden, sunny wall-top or pot, as well as a magnet for bees. Give it the usual oregano treatment of full sun and sharp drainage, and it will flower for weeks.
