Little Salvia that Packs a Punch!

I love this little perennial! This is Salvia chamaedryoides a drought-tolerant perennial from Mexico. It is clothed in soft fuzzy aromatic silvery-gray foliage that mixes well with other arid land plants. After a time in full sun it comes in thick and low, about one foot tall, and chokes out weeds. Hummingbirds love it! It takes a couple of years to get growth like this in a bed. It will tolerate a little shade as it seems to be used to skirting taller plants. As perennials go it is unobtrusive and very attractive even when not in bloom, although, it seems to be in bloom all of the time. It is a good solid workhorse that does its job without shouting. The main blooming period is in the spring/summer for several months and it continues into the fall/winter, with another burst of blooms after the heat of the summer. The only time when blooms are less numerous is in the winter, but it still blooms. In the fall it can look a little rough when it is covered in old bloom stalks, but a quick haircut neatens it up in no time. Just grab a handful of what is sticking up into the air and cut it off. It is as simple as that.

 This plant does root unfrequently at the nodes, but this is a good thing if you want it to spread. It is not a thug by any means, and as gardeners, we know a thug when we see one! If the plant goes where it is not desired you can quickly grab a hunk and trim it off. If you find an occasional rooted portion, yank it out of the ground and replant elsewhere if you desire. Salvia chamaedryoides roots shallowly and is effortless to pull out. It also roots easily if transplanted. For me, this is as close to a "no-brainer" plant as I can imagine.  Also if you have a handful of unrooted trimmings some will root if you just cover the lower nodes with soil, and give them a little water. I have a bed of this plant in full sun and it is around 6 feet by 6 feet in several years. Maintenance is as I described, trimming off spent bloom spikes and pruning back straggler edges. The spent bloom spikes are barely visible until there are many of them because they are a fine spike with no flowers. They become visible because they age to a straw color. The bloom spike is low and short and it blooms from the bottom up so there is an extended bloom period for each spike. Here is a photo.

At one time I had one of the selections of Salvia chamaedryoides, but I think this is the straight species. The flowers are medium/dark true blue with two tiny nectar guides on the lower and upper parts of the corolla. It would be interesting to see this under ultraviolet lights to see what the pollinators see.

This plant is hardy to 20 degrees F. It combines well with pretty much everything. The orange edge of Aloe striata leaves and the orange of the Aloe bloom are a nice color complement to the deep blue blooms. I also like combinging is with clear yellow Argyranthemum frutescens 'Beauty Yellow', Acaulis tetraneuris, Agastache 'Arizona Sun' and Euryops pectinatus. Add in Salvia 'Fire Dancer' for some primary color action. Grasses like Festuca glauca would be nice too. There is a selection called 'Marine Blue' that is supposed to be superior, although, I wonder how it could be? It remains unknown but Salvia chamaedryoides 'Marine Blue' is suspected to the product of Salvia chamaedryoides and, possibly, another species. The flowers are a darker blue and the foliage looks greener to me. It comes in thicker and a little taller too. It is more frost tolerant to 10-15 degrees F. 

While generally easy-care this plant must have excellent drainage. It can certainly get by on very little water but looks much better with periodic water. I probably water around every 10 days. Even though it is technically hardy to freezes if it gets wet during the winter and the soil does not drain well this will take it out. Winter wet and cold are a lethal combination. I found no less than five "common names" for this plant so I will stick with Salvia chamaedryoides. Takes a few seconds to master the pronunciation, but at least we know what we are talking about. Because of the distinctive aromatic furry foliage, this plant is deer and rabbit proof. Look for this plant if you are tired of weeding and want a plant that combines well with everything. The hummingbirds will thank you!
