Teucrium x lucidrys

Updated: Oct 18, 2021


This little germander always finds its way into my gardens, in part for its versatility. I have primarily specified T. x lucidrys as filler, but it has so much more to offer. Its compact form lends itself to tight little hedges, such as Filoli's miniature knot garden that mimics the larger version in the kitchen garden (first photo below, the dark green circle and border is Teucrium x lucidrys). If you have seen traditional flower beds framed with boxwood, this species offers a unique twist on such borders due to its seasonal bloom and small stature.


When grown in informal masses, the flower sprays rise above the dark green foliage where the magenta blooms become a painterly drift. I have noticed on projects that it appears to prefer warmer microclimates and seems less prolific if contending with wind and cold. As with many of these observations, they should be compared with the experience of others.


Native to the Mediterranean region, T. x lucidrys is drought tolerant manages most soils with good drainage. Bees love the tubular flowers, perfect for a pollinator garden. Because of its compact size, add this one to containers where it can billow over the edge of pots.


One point to consider regarding maintenance; deadheading and shaping can be tedious if planted in large masses. Deadheading means crouching over the plants, a tedious task similar to pruning lavender without the fragrant reward. As wall germander finishes blooming, gardeners should take this opportunity to return each plant to a desirable shape, depending on how they are used.


Note: nurseries and people in the trade that do not like change (I am including myself in this comment), still refer to wall germander as Teucrium chamaedrys. The most current name is identified here, but often references will include the older name as a synonym. Don't be like me a date yourself with old names...Teucrium x lucidrys for the win.
