    Where is the Jerusalem Sage currently available in Austin.

    I’m exhausted from talking to people who have no idea what I’m talking about. Often I grower will list places that it has been shipped to but the business (esp Home Depot and Lowes) are clueless 🙁

      Try either Barton Springs Nursery or The Great Outdoors or The Natural Gardner.

      Good luck, its a great plant that is worth locating.

        I’ve seen it at Hill Country Water Gardens too.

    This plant is covered with blooms and bees in the late spring. I have it planted in full sun, but during the summer, even with regular watering, most of it dries up (looks dead). I don’t understand why it is listed as a plant that can take full sun–it has never made it through a summer, yet. It does come back from the roots. I am considering planting more of it because it really seems to be a special plant for bees, but think I need to put it more in shade. What do you think about that plan?

      Beverly Hello,
      Yes it will take partial shade, but won’t get a large, blooms would be lesser and it won’t be “focal”.

      Regarding your struggling Bulbine, not having seen the site I can only think that the soil might be shallow/depleted and you might not have any moisture retaining mulch around it.

      The same plant, planted in a deep healthy soil bed, covered with 2″ of mulch will perform dramatically different than a plant planted in compacted caliche soil with no mulch and that was planted in the heat of the summer.

      Thanks and good luck!

    How can you list as common names for Phlomis, “Satiny Wormwood, Mugwort, Silvermound Artemisia”? The plants COMMONLY called these names, being Lamiaceae, are not even in the same family as Phlomis! They all are artemisias – members of the Asteraceae family! This is a pretty big error, IMO, and should be corrected.

    I used to live in Pennsylvania, and visited Austin about 12 years ago, where I purchased a P. fruticosa at a nursery. The plant thrived in PA. Sorry – I cannot recall the name of the nursery, so cannot help those of you looking for it. When we moved to Ohio about 8 years ago, I took a couple of crowns of my plant along, and have divided and shared the plant here a number of times since then. It grows equally well in shade as well as sun in my yard, and spreads fairly readily, being a member of the mint family. 🙂 The mature seed stalks are very interesting in a dried arrangement.

      The common names is a tricky category and doesn’t really have a cut and dry solution. I put that category for folks coming from a different gardening region and know that plant or a plant that looks like it by a different name. You should always go by the botanical name to avoid confusion but those names tend to be long and hard to pronounce and not easy on people with basic botanical knowledge.

      For example, Pride of Barbados and Bird Of Paradise always get confused in this neck of the woods. When Clients ask for Bird of Paradise, 90% of the time they mean Pride of Barbados. It’s an entire different plant although looks similar.

    A neighbor put our one of these and promptly moved. Saw it again at Cedar Park
    Library. It certainly lives thru the summer there, although the seeds dry up.

    Love! your web sit, which I just today found. Thanks.
