sage-leaf mullein

For Sage-leaf Mullein (Phlomis tuberosa) to flourish, it is important to properly care for it. Water should be applied deeply and slowly once every 7-10 days. Watering the root zone thoroughly can help the plant to tap into its deep root system, and it should be done early in the day so the foliage can dry out before nightfall. Mulch can also help to retain soil moisture, and should always be applied after watering. During dry spells, ensure that the plant receives adequate moisture by adding an additional deep watering. The soil should remain slightly damp between waterings.

Native to rocky hillsides of the Mediterranean, Sage-leaf Mullein thrives in dry, sunny conditions. In order to maximize its growth potential, this plant species should be placed in full sun – meaning that it should receive adequate sunlight for 6 to 8 hours every day. If the Sage-leaf Mullein is exposed to too much shade, flowering will be reduced. It is best to plant this species in late spring to early summer so that it will be exposed to the most sunshine and warm temperatures.

Sage-leaf Mullein (Phlomis tuberosa) should be pruned early in the spring or late in the summer, before the new growth begins. Prune away any dead or weak stems and remove any spent flowers. Pruning should be done sparingly, as the plant produces its colourful flowers and attractive silvery-green foliage on stems that were produced the previous year. Trim any stems that are crossing or extremely unruly to keep the plant neat. Don't prune more than 1 third of the plant as this could damage it.
