Excellent perennial, blooming machine and pollinator magnet, modest and great-sized plant.
One of the exceptional plants that originate in Europe and deserve more use in American gardens and public landscaping.
Perfect-sized mounds of 1.5-2' of height and width, with somewhat groundcovering growth, small white flowers from June till frost!
Highly attractive to many kinds of pollinators, native bees, honey bees and butterflies too.
Full sun is the best, but it will tolerate some little shade during the day (half shade, partial sun), but it is proven, that it will do fairly well in lighter dry shade - the soil has to be well drained and really drier.
Average soil, drained soil, with average moisture to drier or dry is the best. It will tolerate even moist soil, but those have to be drained! seems to do well in heavier soil or clay, that is not waterlogged and has tendencies to dry out (slope, drier zone of tree roots).
Hardy in zones 4 to 9.
It's strong minty scent makes it deer and rabbit resistant plant!
Be aware - this is sterile plant, that doesn't self seed at all, similar sterile cultivars are 'Montrose White' and 'Triumphator' (sometimes called 'White Triumphator') - those are all excellent and safe plants - and you recognize them easily - they have glossy leaves without hair.
While there seed cultivars that are on the market and those can become problematic seeders, especially in drained soils or in Mediterannean climate - these all originate with Calamintha nepeta ssp. glandulosa (this one has hairy - fuzzy leaves, which is the main distinguishing characteristic) - these have names like 'White Cloud', 'Blue Cloud', 'Marvelette Blue', Marvelette White'! They are still great plant, but they will seed up t a problematic point.
Superb perennial for edges of sunny border, or in the middle of the beds, it is more "filler plant" that wants to be combined more rough structure of medium sized to medium/tall perennial and fills the gaps and hides the "dry legs" (leaves) of taller plants.
The best combinations are for example with Echinacea, Rudbeckia - R. missouriensis, R. hirta, R. 'American Goldrush', R. fulgida var. deamii, but it will look wonderful with Allium ' Summer Beauty', Allium 'Millenium', Aster oblongifolius, Geranium sanquineum, Helenium, Liatris aspera, Lobelia siphilitica, Monarda bradburiana, Penstemon, Solidago, and grasses like Schizachyrium scoparium, Sporobolus heterolepis or Sesleria autumnalis.
Or it nicely resonates with similar, but different Agastache o Perovskia.
Because it flower for incredibly long season, it offers amazing background for the dry seadheads of Echinacea, Helenium, Penstemon or Rudbeckia.
