Spearmint Seeds! mentha spicata
Bright to medium green ovate shaped leaves with strong sharp toothed edges up to 1 1/2" long. Leaves are arranged in opposite pairs on a stoat square shaped stem. Growing to about two feet in height they produce numerous whorls of flowers in slender spikes at the end of the stems in mid to late summer. Flowers are small tube shaped pale lavender to white in color. Although not very showy in their own right they can be quite noticeable en mass.
Care and Placement.
Spearmint likes sunlight. It can grow in partial shade but it tend to be lanky. However in areas where days are long and hot a little afternoon shade would be beneficial. Sunlight increases the production of the essential oils that give the plant it's wonderful smell and taste so if you intend to use it make sure it has plenty of light.
It is a very resilient plant and can grow on almost any soil type with only a little water. It is very happy in moist soils so heavy clay and soils that retain water well are idea. If growing in sandy soil if the area does not get intermittent rain some water will need to be added. It can tolerate fairly acidic soils but will also grow well in an alkaline environment.
The creeping root system can travel quite long distances to create more plants so don't expect a narrow pathway to stop it's spread, a driveway most likely would be a challenge for it however. In a sunny area once established it can quite easily beat out native plants and produce a nice ground cover, although woodland edges may be more difficult.
Growing from seed.
Do not cover the seeds; they need light to germinate. They should sprout within 10 to 15 days at room temperature or slightly warmer (68 to 75°F). Transplant into the garden or container when they have at least 2 sets of true leaves.
