Spearmint is a plant which belongs to the Mentha genus. The origin of this plant's scientific name epithet (spicata) means 'bearing spikes'.
Spearmint is used most commonly in the kitchen for mint juleps, sauces, jellies and teas. Spikes of lilac-pink flowers bloom in summer. Attractive in borders and containers. Popular with bees. Very invasive. Take this last part seriously, It will take over your garden if you let it.1
Like most mints these are easily propagated from cuttings, in many climates they can easily take root while sitting in plain water.
The plant has square shaped stems and soft oval leaves with a slightly indented edge placed in pairs at a prominent node on the stem.
The flowers small and grouped close to the stem at the leaf nodes
Blooms typically mature to a diameter of 0.2 cm (0.08 inches imperial) and produce a menthol fragrance, whilst displaying in these approximate colours: Pale lavender and Lavender pink and Medium purple. The mature flowers are of a single hose-in-hose form. Leaves appear approximately as a Kelly green and Dark spring green
Spearmint is a flowering edible herb / flower perennial, it will last at least up to several years in its native climate.
Spearmint normally grows with a forb habit to a mature height of 45.0 cm (that's 1.46 feet imperial). This plant tends to bloom and harvest throughout the year.
Try planting Spearmint if you'd like to attract butterflies and bees to your garden.
Spearmint is normally fairly low maintenance and is normally quite easy to grow, as long as a level of basic care is provided throughout the year. Being aware of the basic soil, sun and water preferences will result in a happier and healthier plant.

Although hardy, it survives as an underground root system in winter, so leaves must be preserved to have supplies in winter.
Keep cutting plant down to encourage fresh young shoots
Cut down in the late summer for a fresh flush of leaves before winter.
If pot grown, mint will need watering well and fertilising in the growing season. Top up the compost as the season progresses
Enjoys a partial sun position in your garden and remember to water moderately. Zone 4 to 11 are typically the USDA Hardiness Zones that are appropriate for this plant (although this can vary based on your microclimate). Ensure your soil is loamy, potting mix and clay and has a ph of between 6.5 and 7.0 as Spearmint is a weakly acidic soil - neutral soil loving plant. Keep in mind when planting that Spearmint is thought of as hardy, so Spearmint will tend to go dormant or grow slowly over the winter months.

Sowing from seed is possible, but whenever a cutting can be used, use it.1
Place the seed on the surface of the compost and do not cover, cover with a plastic bag and keep reasonably warm at between 20 and 25C until germination which can take up to 21 days. Do not exclude light as this helps germination, grow on at cooler temperatures.
When seedlings are large enough to handle pot up individually into 7cm pots and grow on in cooler conditions. Plant out after frost has passed. It would be wise to restrict the growth by planting in a pot, as the roots spread, invade and regenerate from the smallest section of stem or root
Alternatively plant up in a large flower pot and keep on solid ground to prevent the roots escaping. It will need more care in a pot.
Good for mint sauce, chopped and added to wine vinegar and a tiny amount of sugar. For a change, mix chopped leaves with lemon juice and a drop of honey.
Chop an add to new potatoes or fresh peas. This mint is used for mint tea.
Use fresh young leaves, to encourage these trim the plant periodically
It is easier to start from cuttings than from seed
