Flowers

Flowers are harvested after planting mithril seeds, which are obtained after completing the Waterfall quest and can also be bought in the Legends Guild.

The primary colour combination can be bought from the Flower Girl on Miscellania for 15 coins. Flowers grow in many assorted colours with black and white being the rarest and the primary colours being the most common.

When planting the mithril seeds, players have an option to either pick the flowers to obtain the item, or to let them grow. Flowers that are left to grow will stay on the ground temporarily, for a bit longer than five minutes.

Picked flowers can be wielded in the weapon slot and are known as a fun weapon in Duel Arena because it gives the wielding player a negative strength bonus.

Types of flowers
Yellow are the most common and therefore the least valuable of all the types of flower. Orange are the next most common. Blue and Red were tied for next most common.

However, red flowers are now used in Summoning. Red flowers are the tertiary ingredient in infusing Praying Mantis pouches and currently sell for around coins.

The Lavender-Purple-Pastel blue combination and plain purple are the next most common variety. Black and White are the rarest colours making them the most valuable of all flowers.

Historically, growing flowers was a good way to make profit. However the prices of flowers dropped significantly after the advent of the Grand Exchange. White flowers are the highest selling flowers, currently going for around coins. While black flowers sell for around coins. All other flowers are usually less than 50 coins.
