Native and Invasive Irises (Iridaceae)

If there is one thing you can be sure of, as you learn more about plants and how to identify them, the clearer the destruction of native wildlands gets. Soon the beautiful flowers you see in a wild reserve turn up to be aggressive invasive species brought to the continent by people wanting a more European garden.

Today I want to show two species of Irises that can be found in New Jersey, North-Eastern America, Iris pseudacorus (Yellow-Flag Iris), and Iris versicolor (blue flag Iris).

Both species look similar, but, in my personal opinion, the native Iris looks far better than its European cousin. But, as the yellow-flag were quite popular in Europe they were imported for their ornamental value.

Both species like wet conditions to grow in and are found growing near ponds or swamps. Yellow Flag Iris takes over aquatic habitat and out-competes native plants by forming thick clumps that are hard to remove.

Adding native plants to your garden has a lot of advantages. Besides making your yard look beautiful, they attract and provide shelter to native insects and help restore the land to its original splendor! You can find links to native gardening websites here.

Go ahead, slide between the two flowers, and tell me which one is prettier!

Eastern (Red-Spotted) Newt

Notophthalmus viridescens,the eastern newt is a common newt found across eastern North America. The adults are not as striking as the juveniles (efts), which are brightly colored to warn you of their toxins.

Shown here is an individual eft we stumbled across in high point state park, New Jersey. The swamps of the High Point are unique and are biologically diverse. You can learn more about the bog here on this excellent blog that goes through its natural history and its unusual evolution.
