Plant this sub-shrub edible herb in well-draining soil that is neutral to alkaline, ideally in a sunny location. It thrives in sandy loam and requires excellent drainage to flourish. Once established, it demonstrates remarkable drought and heat tolerance, making it suitable for the sweltering summers of the South. However, it may struggle in cold conditions, so using containers that can be brought indoors during winter could be a wise choice. This herb can be planted in borders, along pathways, in hanging baskets, or window boxes, and can also be grouped together on slopes. To promote a fuller, bushier growth, pinch or prune the stems before the summer flowers emerge. For the best flavor, harvest the leaves prior to flowering. Its taste is milder compared to O. vulgare. The flowers themselves have a sweet, spicy flavor and can be incorporated into soups, stews, dressings, and sauces.

In terms of pests, diseases, and other issues, this plant does not face significant challenges, but it is susceptible to rot in poorly drained, waterlogged soils.
