Rosemary plant is one of the most popular herbs in the garden. There are many kinds of rosemary plants available in the market today. They vary from small shrubs to large trees with huge branches. All these varieties have their own unique characteristics and qualities which make them suitable for various purposes. Rosemary is a member of the mint family, which includes such well known herbs as oregano, thyme and basil (the three main members).
The name “rose” comes from the Latin word rosa (“flower”) and marmora (“marble”). These two words together mean “beautiful flower”. The leaves of rosemary are usually green or pinkish white, but they may also be purple, red, yellow or even black. The flowers are tiny, pale pink to lilac colored and up to 1/4 inch long. They grow on stems up to 6 inches tall.
There are several species of rosemary. Some are perennial, others bloom only once a year and some are annuals. Most varieties grow best in full sun, but they will tolerate partial shade. They prefer moist soil and thrive in sandy or loamy soils. They do not like dry conditions at all!
They need regular watering during the summer months when they produce their beautiful flowers.
