Fun Facts About Rosemary

  • Rosemary is a plant of the mint family with fragrant evergreen leaves. The plant is native to the Mediterranean region, but it has been introduced into many other regions of Europe and around the world.
  • The name comes from the Latin “ros marinus” meaning “dew of the sea”. This refers to rosemary’s fresh smell, which resembles that of an ocean breeze. For ancient Greeks and Romans, it symbolized remembrance because its flowers are particularly long-lasting.
  • Rosemary can grow up to 2 meters (80 inches) tall. The stem is woody near the base and grows into long, green needle-like leaves that are most often used in cooking.
  • The flowers of the rosemary plant are white with 4 petals and grow in clusters of 2-5 blooms on top of spiny branches. They bloom during spring or early summer, depending on climate – they bloom earlier in cooler climates. Rosemary is not self-fertile; cross-pollination must occur for seeds to be produced, so it can sometimes be challenging to grow this herb if you live in a small space like an apartment.
  • Rosemary is associated with remembrance because its petals last longer than other flowers. The flower’s fragrance has also been used to keep memory.
  • It is a herb that can grow in deep shade, but it does well in full sun too. Its growing conditions are similar to those of lavender. Rosemary is mostly grown outdoors, although it can also be grown inside at home or office spaces.

Rosemary Grow Tips

  • Plant Rosemary with other herbs like basil or thyme that are similar in climate needs
  • Give it plenty of sunlight; they prefer full sun (6 hours), but can tolerate partial shade if necessary.
  • Make sure the soil drains well, as they dislike wet roots.
  • Plant in late spring or early summer (June-July), and harvest when leaves are dry and no longer fragrant.
  • Make sure the plant gets enough water, but not too much or too little so that it doesn’t dry out. (Watering too much will cause root-rot). When watering, water deeply until the soil is wet, then wait until the top 1 inch of soil dries out before watering again.
  • Start with the right soil mix – this will make all the difference in how your plants thrive or wither away. Mix two parts potting soil with one part sand and add some fertilizer like composted manure for an extra boost of nutrients. 
  • Plant between 6 inches and 1 foot apart, so they can share nutrients.
  • Trim back flower stalks after blooming to keep the plant looking neat and compact.
