Defining Spearmint vs Peppermint

Difference Between Peppermint and Spearmint

For people who don’t know, spearmint and peppermint have a lot of differences, from the flower, the leaves, and even their flavors. They were known to have values for the effects that their oils have, but each of them is used differently. 

Both of them maybe from the mint family (Lamiaceae), but they are from different species. Spearmint is the species of Spicata, while peppermint is of the species of Piperita.

Let's dive deeper into each plant.

Spearmint (Mentha spicata)

Spearmint is a aromatic herb that is often touted for its medicinal uses, as well as culinary and cosmetic! Spearmint can be used to aid in the digestive process as well as improve memory function. 

The leaves of spearmint are bright green and pointed and the plant grows a lovely lavender flower. The plant can reach up to 24 inches high and wide in ideal conditions.

How to Grow Spearmint at Home

Growing spearmint is quite easy! It is hardy perennial that will come back every year. It is fairly low-maintenance, mostly needing regular trimming.

Air dry the trimmings and store in an airtight container for use later. Spearmint likes the sun, but be careful when planting spearmint in direct sun if you live in an area with a very hot climate. 

Direct sunlight during the hottest part of the day could cause damage to the leaves. While it is easier to grow from a plant, you can grow it from seed. 

It is quite difficult to grow spearmint from seed, however, if you wish to begin with seed, be sure to wait until the ground warms up and then once the seeds are planted, keep them moist until they have germinated. 

Planting Spearmint

Spearmint plants like rich soil with a pH level of 6.5 to 7, though there is a little wiggle room. It grows very quickly and can take over your garden.

There are a couple of ways to combat this: one is to plant them in a pot or hanging basket and the other is to plant them inside a container within your garden bed.

If you choose to do this, use a 5 gallon pot and cut out the bottom before digging out the space in your garden bed. Both options will help keep the spearmint plan from running amok! 

Caring for spearmint is also quite easy. If you plant it in a garden bed, be sure to put in new mulch every year. If you plant it in a container, use a liquid fertilizer each month during the growing season. 

You will need to divide the plants every couple of years to allow them room to grow and stay healthy. Potted plants will need to be pruned. Bring in potted plants during the winter if your area gets very cold. 

Spearmint even grow under artificial light and in grow tents

Spearmint Pests and Diseases

Even low-maintenance plants can have diseases or pests. Following we take a look at the very few that mint plants have at times. 

Twospotted Spider Mites

Twospotted spider mites are insects that lay their eggs on the underside of mint leaves. They will then attack the plant as will their offspring. Avoid planting mint in areas that are dry and dusty. 

If your plant shows signs of spider mites, make a neem oil spray and soak the plant and soil with it. You can use it proactively as well before the mites become a problem. 


Is a fungal infection that causes mint plants to have brown or black spots on the leaves. The only treatment for rust is to completely destroy the plants and replace them.

Avoid getting the leaves and stems wet by watering only at the base of the plant. Fortunately, this is typically an issue that only occurs with indoor planting. Make sure the room you keep mint plants in is well-aerated. 

Verticillium Wilt

Is another fungal infection that is caused by too much moisture and will cause the plant to wilt and then die. Again, this issue is usually only present with plants that are kept indoors.

Water only at the soil level and keep in an aerated room. 

Peppermint (Mentha × piperita) 

Peppermint was created from watermint and spearmint in 1750. Since that time, peppermint has become widely popular for its medicinal uses, rich flavoring and pleasant fragrance.

Peppermint (Mentha × piperita)

Peppermint is often use to aid in digestion and for colds. Peppermint oil is often rubbed on a person's temples for headache relief. There are actually two types of peppermint, black and white. 

The black peppermint has a stronger flavor and higher oil content than white peppermint. Also, black peppermint is a deep purple-green while white peppermint is a light green.

How to Grow Peppermint at Home

Planting peppermint isn't difficult, but there are a few things you need to know. Peppermint does need a lot of moisture and it prefers full sun.

It also needs to be completely relocated every three to four years. While peppermint isn't quite as invasive as spearmint and some other mint species, planting it in a pot or in a bed with some edging is a good idea.
