I know it is hard without a pic of it! And, I realized when you replied that I forgot to mention that it is not fragrant at all. Even though it looks and feels like some type of herb. So, not a sage. By looking at it you would think sage or lavender with the grayish leaves and the flowers. Thanks for replying! I have been trying to do Google searches to try and find out what it is, and how to propagate it. I tried a hardwood cutting for my MIL, but it didn't take. Sred

You can take cuttings from any plants at any time you like. To get them to grow, however, they prefer warm conditions - they just take longer to grow in winter (cold) because most plants are dormant when cold. Spring is the usual time recommended, but if you live in a cold climate, cover the cuttings, pot and all, with a clear plastic bag 'tent' to maintain warmth and humidity. Minimum soil temp for growing for most plants is around 16C. You may need to provide bottom heating to achieve this. Ignore atmospheric temperature - it's the soil temp which controls growth. Though of course, if you have consistently warm atmospheric temps, your soil temp will also correspond to that warmth somewhat (ie the soil will be warmer if your weather is warmer).

Lavender_lass is correct. Knowing which lavender will make a huge difference in what we have to say. I seem to recall some of the spanish lavender types being hardy to zone 8, which is tender even for you. I don't grow those types since they are way out of zone for me so someone with more experience on those can comment. But regardless of the type, excellent drainage will be the key to winter survival. Any place that water pools in the winter will mean a sure death for these plants. I have lavender (very hardy english types only) come back for me each year. They survive the cold, ice, and snow of my region so overwintering outdoors, so long as your plants are hardy for your zone is very possible and rather easy. FataMorgana

Wow! what a difference in zone 8's. ROS doesn't start blooming here until July at the earliest. FWIW - a very good reason why it is important to give your location as well as hardiness zone.
