Why We're Featuring a Crocosmia Plant Profile for June
You could say this star in the garden "captivated" our attention long ago with its uniqueness and beauty. Therefore, it just had to be our pick for the June plant profile of the month (Yes, we know it is technically July. Call it a bit of a "summer brain" delay on our monthly plant profile posts.

Our Crocosmia plant profile guide below is meant for beginner gardeners but can be used by anyone who wants to learn more about this captivating plant. We hope it's helpful!
Crocosmia Plant Profile: Brief History
The Crocosmia, part of the Iris family, originates from the tropical areas of Southern Africa. Over time, the plants have been bred and propagated throughout the world.
The name comes from the Greek words of Krokos (Saffron) and osme (odor) referring to the smell of dried Saffron leaves.
In 1879, a Frenchman was able to cross different species together thus initiating the variety of Crocosmia cultivars we have in existence. Today, this beautiful plant has over 11 species with numerous varieties and cultivars.
Did you know that this plant is actually considered a weed in parts of England, Australia, New Zealand, South Africa, and parts of Hawaii? Due to its vigorous breeding over the last couple hundred years, Crocosmia adapted so well it became a nuisance. This speaks to its overall adaptability. These plants can easily reproduce to fill in open spaces in your garden. Good thing they are easy to dig up and place in other parts of your garden by transplanting their Corm (a type of bulb) root-system. By the way, if you haven't encountered a "corm"- a type of bulb plant - before, think of a Tulip or Daffodil bulb and then squish them so they are more flat than tall and you have a Corm.
Crocosmia thrives so well it is perfect for beginner gardeners. Also, it makes a great addition to containers on patios or decks.
