What Aquatic Plants Should I NOT Put in my Phoenix Pond?
There are LOTS of great choices for aquatic plants to put in your Phoenix pond. In fact, many terrestrial plants can be used in Phoenix ponds, as well.
However, there are several plants that you should absolutely avoid adding to your Phoenix backyard pond.
Yellow Iris (Iris pseudacorus) in a PHoenix Pond
This is not your typical Louisiana Iris that stays demure. This guy is a monster! If you're going to use it, you must absolutely stay on top of keeping it thinned. Here's what happens when you don't:
Bamboo in a Phoenix Pond
Although you might think that bamboo and ponds just naturally go together, this one is a huge no-no. It's roots (stolens) are super-sharp, travel underground, and will puncture even concrete, let alone any kind of liner. And it gets pretty darn big!
Cattail (Typha) in a Phoenix Pond
While the dwarf variety is fine, stay away from full-size cattail. Like the Yellow Iris, it can get out of control quickly. It also spreads via it's fluffy seed. Check out a quick video shot at the Hyatt Regency Scottsdale of this aggressive plant and what it takes to remove it:
Illegal Plants for Phoenix Ponds
There are some plants that are flat-out illegal in Arizona. Sadly, one of those is Water Hyacinth because irresponsible people have tossed them into canals and waterways, where they grow unchecked and clog up the systems. There are clubs and private parties that will give you cuttings, but it is absolutely illegal to sell, and the State looks unfavorably at anyone keeping it in their pond.
