After a long break, we are happy to continue our individual Texas native plants profiles and today we will put the spotlight on Golden Showers Thryallis (Galphimia glauca).
From the entry:
“Golden Showers will shower you with golden flowers for a very long period, starting at spring and continuing up until frost. Thryallis is an evergreen, although it will die down on especially harsh winters. With modest water requirement, extra long blooming season, very low general maintenance, and being highly deer resistant this Texas adapted shrub is becoming increasingly popular in Full sun, heavy deer pressure flowerbeds. Give it a try!”
What do you think about Golden Showers Thryallis? Do you grow it yourself? What kind of experience and insights you have to share? We love featuring our readers’ plant pictures and Xeriscapes!
Is Galphinia glauca plant perennial? Will it survive harsh but brief winters of SC if I cover it in burlap? Any suggestions how to keep this plant alive over the winter? Thanks.
We love SC!
Golden Showers is indeed a Perennial but unfortunately it is hardy to 25F meaning that even in sunny Austin it will not survive especially harsh winter.
You could try to save it by planting it near a south facing wall, heavily mulch it. Some folks in Austin are able to grow various citrus here by use wrapping the trees with Christmas lights.
The best course for you might be picking up a more climate appropriate plant. SC is famously botanically rich!
Thanks and good luck!

I love the look of the plant when it flowers so I bought one. I just planted one and I dont know if it transplant shock or what but it really seems to be struggling hard in the july heat. I was told that the water requirement would be low once established. So far it is showing both signs of heat stroke and over watering. I hooked it to a drip line to ensure it would not dry out and many of the lower leaves started turning yellow (sign of too much water?) I then moved the plant to a sunnier spot wasn’t getting much water and now the leaves look as if they are wilting and more yellow leaves on the bottom. Any advice? I love this plant, but so far it has been a handful and not what I would expect from a native Austin plant.

Is it suitable to plant a thryallis this time of the year??
Connie,
Yes! Fall is the very best time to plant plants in Austin. The more time the plants have before facing our harsh Summers the better. Just make sure to initially water the plant until its established and it will work great.
Let us know how it turned out!
Thanks,
Reed
Hi – I was gifted a GOlden shower yesterday. Would this be good for a butterfly
Garden? Can I plant it in a large container?
We planted thryallis (4) last fall against a south facing rock wall that is about 4 Ft tall. We live 8 miles south of Harper, TX in Gillespie county. We had what we consider a cold winter with very little rain, but I did water them at least 1-2 times each month. They are not showing any beginnings of breaking dormancy. Our cape honeysuckle is leafing out from the roots. How long should I wait until I begin to pull the earth away from the roots to see if they are still viable?
