October birth flower
Marigold
The plant
Tagetes, native to Mexico and Central America despite common names like African and French marigold. The pot marigold, Calendula officinalis, is a separate European plant that shares the name.
Why it belongs to October
In Mexico the orange cempasúchil, Tagetes erecta, is laid on altars and paths for the Day of the Dead, its color and scent said to guide the spirits home. In India marigold garlands are used at weddings, festivals and temples.
Meaning by color
Orange and yellow for warmth, creativity and the sun. Victorian lists also linked marigolds to grief, so they suit remembrance as well as celebration.
Keeping it
Deadheading keeps them flowering. French marigolds are often planted among vegetables because their roots can suppress some soil nematodes.

Cosmos
The plant
Cosmos bipinnatus, an annual of the daisy family native to Mexico, with feathery leaves and flowers in white, pink and crimson. Chocolate cosmos, Cosmos atrosanguineus, genuinely smells of chocolate.
Why it belongs to October
Spanish priests in Mexico are said to have named it after the Greek kosmos, meaning order and harmony, for the evenly spaced petals.
Meaning by color
White for purity, pink for love and gentleness, crimson for passion.
Keeping it
Cosmos flowers best in poor, dry soil; rich soil produces tall leafy plants with few blooms.
Giving October birth flowers
An October bouquet of marigolds and cosmos is bright and inexpensive; for a longer-lasting present, a packet of cosmos seed can be sown the following spring.
