Thryallis – Showers Of Gold (Galphimia glauca)
Thryallis is one of the terribly underused and under appreciated, beautifully adapted jewels in the Central Texas landscape. This full to part Sun semi-evergreen, flowering shrub is a great replacement for the terribly overused shrubs most homes have parked outside their windows. Too many cookie cutter plants are used in place of something unusual and this is one of those times when an alternative can be a fun option.
Golden Showers Thryallis
Obviously this is a beautiful shrub, typically reaching 4-6′ tall and about 3′ wide at maturity, which it reaches rather quickly as it is a pretty fast grower. What I also love about it is that is not as dense as many of the evergreen options we have here. Very few of the typical “front bed” shrubs the builders commonly use have flowers at all and most that do are short-lived. This shrub blooms late in the season, usually around August or so, but has a steady pattern of blooming until the first frost. I also love that it requires no trimming!!! Yeah, no trimming…when you are constantly trimming back your hedges, this is a big deal. When properly spaced and given adequate sunlight, this is a great low water, low maintenance, deer resistant shrub. The Winter time is a bit tricky because the shrub tends to be sparse and multi-colored rather than a true evergreen, but well worth the sticky Winter appearance considering the fabulous Summer rewards.
Try this shrub the next time you are considering a low maintenance, low water, semi-evergreen flowering shrub and set a new trend for your neighborhood.

I tried Thryallis this year for the first time and was concerned about it’s winter hardiness, but much to my surprise, the plant is still green in mid January and bloomed in shade this summer. It exceeded my expectations and I would now recommend it to others.
Bob, I just love this plant and have used it for years from Georgetown TX to Westlake and in between. It is a spectacular bloomer and I really dig the interesting foliage. Great performer!
