Growing Oregano in a vertical garden

Low-growing, ground-covering varieties such as aureum or hirtum are slightly slower
growing than their common cousins, but will grow compact and dense to fill the space
in a vertical garden. Its sweet aroma is heightened when planted in prime conditions:
full sun, poorish soil and good drainage. It is a very easy herb to maintain. Oregano is
fairly heat resistant and prefers a neutral to slightly alkaline environment. It is also a
good companion plant and is said to repel pests.
