Silverleaf nightshade – the beauty is a beast

Silverleaf nightshade is a beautiful plant, but the beauty is a beast!  The silver leaves are attractive, but their blue flowers with prominent yellow stamens attract a lot of attention.

 

 

 

This plant’s attractive characteristics hide some unattractive features.  It is related to deadly nightshade and is itself listed among  plants toxic to both humans and livestock.  More than that, it is listed as a noxious weed in several states and acknowledged as a weed in most others.  It is, however, a relative of tomatoes, tomatoes, and chiles.  These are all members of the Nightshade family, Solanaceae, and most members of this family do contain toxic elements in some of the plant parts.

If that was not enough it produces spines on most above ground parts of the plants.  While some plants produce more spines than others, and it has been reported that plants growing in humid climates produce few or no spines, for gardeners in the Southwest, this plant produces some spiny problems.

 

There are even spines on unopened flowers of silverleaf nightshade

Silverleaf nightshade is a weed with a deep taproot that allows it to survive in very arid environments.  Even a small piece of root left in the soil will generate a new plant.  Plants in a clump are often attached to each other by underground stems, so that they can help support each other.  This makes them survivors, it also makes them weeds.

 

As weeds we try to remove them, but be careful, the spines easily break after piercing your skin and become difficult to remove.  These spines can sometimes even penetrate leather garden gloves!

So can there be anything good said about these plants?  Well, they are beautiful, but the beauty is a beast!  They are toxic, but like many toxic plants, the toxic principles can be curative when used properly.  They were used medicinally and as beneficial plants by native people.  They were even able able to use the ground, dried, fruit to curdle milk to make cheese.

Never the less, the beauty is a beast!

Golden Currants consistent production even in drought

Ribes aureum – Golden currant fruit ready for harvest

Golden Currants, Ribes aureum, are a reliable, consistent producer in my garden.  The black berries must be picked individually by hand, but make a delicious jam or preserves.  In this drought year when the garden has received only about 2 inches of precipitation since October, none from October to January and none in April, it still made a crop.  I did irrigate a few times, but only minimally.

Even after harvesting over 2 gallons from a few plants, there is much more to harvest.

Birds and a berry moth (their larvae) are the primary problems, but I still have a bountiful harvest of tasty berries.

Fragrant golden flowers followed by abundant harvest, even in times of drought, make these reliable producers a good choice for gardens in New Mexico.

How to tell if seed are good

I often have seed left from previous years and wonder if they are viable.  Sometimes my plants will surprise me with seeds, but these seed often are not viable and do not grow.  Testing the ability of these seeds to germinate saves time and space in my garden.  Recently my gerbera daisy made seeds, so I tested them.  I also found some one-year old liatris seeds that I decided to test.

I put the seeds into sealable plastic bags on moistened paper towels, each type in separate bags:

After a couple of weeks the liatris seed were sprouting, but there was no sign of growth in the gerbera seeds:

I carefully removed the sprouted liatris seedlings from the moist paper towel and placed them into pots of potting soil:

They are growing well and I will transplant them to the garden later in the spring, or give some to friends.
