Phlomis Russeliana

Successful growing of Phlomis begins with understanding its natural resilience and modesty. Since you will receive an already grown seedling, complicated pre-growing is eliminated, and you can place it straight into a permanent location. This plant will thrive in places where other perennials fail due to drought and poor soil. It seeks out sunny and warm locations, while also tolerating partial shade as long as the soil is not too damp. The soil should be rather poorer, well-drained, sandy to gravelly. If the soil is too nutritious and humous, the plant may become leggy and bloom less. When planting, make sure that the neck of the seedling is not submerged too deep underground, and after planting, water it so that it connects with the existing soil.
During the growing season, caring for Phlomis is very easy, which beginner gardeners will especially appreciate. Thanks to deep roots, the adult plant reaches for moisture itself and handles summer droughts excellently. It is not necessary to fertilize it; on the contrary, in poorer soils it is more compact and resilient. Its gray-green leaves create a dense ground cover that effectively suppresses weeds. If the plant starts to expand too much in width (it self-seeds and spreads by rhizomes), you can easily restrict it with a spade or by installing root barriers. The flowers are not only beautiful to look at, but they are also a magnet for bees and bumblebees, and if you cut them for a vase, they stay fresh for a long time. They are also perfect for drying into dry arrangements, where they retain their shape.
As for wintering, Phlomis is a fully frost-resistant perennial (zone 4a), which will survive the winter here without any problems. In autumn, avoid the urge to "tidy up" the garden and leave the dry stems in place. Not only will you support the garden's biodiversity by doing this, but you will also gain a gorgeous winter decoration right in the flowerbed. Spring maintenance then consists of removing these old stems and possibly damaged leaves so that the plant can sprout again. Because pests and diseases avoid Phlomis, you do not have to worry that leaving the old matter over the winter would cause health problems for the stand.
Growing in a planter or pot on a terrace is also an option for Phlomis, ideal for livening up sunny balconies. However, choose a container with drainage holes and use a substrate for herbs or succulents, or garden soil mixed in a 1:1 ratio with sand or perlite. In a container, there is limited space for the roots, so the plant will require occasional watering during hot days once the substrate dries out. For winter, it is advisable to insulate the container or move it closer to the wall of the house so that the root ball does not freeze as quickly as in the open ground, although the plant itself tolerates frost excellently.
