Tamarix, Five-Stamen Tamarix, Saltcedar, Salt Cedar, Tamarisk 'Summer Glow'

I love the tamarisk's lacy foliage, but it's a pest here in Utah. The entire Green and Colorado river systems have been invaded by them....Read More They line the banks of both rivers so thickly that no native species can grow on the banks. You can't even approach the bank on foot because of the density of the tamarisks.

Furthermore, mosquitos love them. I was on a river run many years ago down the Green river, and we had to stay in the middle of the river; if we got close to shore, the skeeters got us.

However, if you have a place where you get too much water but a lot of sun, the tamarisk is the shrub for you. My sister, who lives near Boise, ID, has a problem spot where the water from the neighbor's lawn puddles on top of a hard stratum of rock not far below the surface. The puddling has killed a cherry tree and several pines, but the tamarisk is as happy as a clam at high tide.

This tree produces amazing cooling capacity when found in large stands. In Las Vegas, lining the Las Vegas Wash draining all sto...Read Morerm water and treated wastewater to Lake Mead, this tree is common. Yes, it has taken over but in a stark barren landscape such as is found in some parts of the desert, the stands of tamarisk cedars are a welcome cool respite from the scorching heat.

My questions are: how long are these seeds viable after being borne from the tree? How can one obtain the seeds?

North Dakota has this plant listed on it's invasive/troublesome list and has put out flyers and cards with the following information:...Read More />

Several years ago I ordered a Tamarix through the mail,
planted it out front and waited. And waited. And waited.
Finally, y...Read Moreears later, it is just now beginning to put on
a show worthy of looking at.

While it is a pretty color and produces light and airy
whispy strands to adore in the breeze, it's hardly the
show I was expecting.

Strangely enough, Tamarix is considered an invasive
species. I've waited for years for this, so I can't fathom
the invasiveness. Perhaps I am just growing a dud.

I am well aware of the reputation of this plant and invasive species. These shrubs are easy to spot and I have never seen one out of it's...Read More captivity. It is an unusual accent plant.
