You might phone the arboretum and see if this is a hybrid they will have for sale at their spring sale. Probably not readily available in the trade, as much of what UCSC comes directly from Australia and has not been taken up for propagation here in California. Also, it might help to know that this hybrid might not be fully hardy in Sacramento, and many of the more commonly available species/hybrids are also hummingbird magnets. I would suggest looking on line to see if either Monterey Bay Wholesale Nursery in Watsonville, Sierra Azul Retail Nursery in Watsonville, or San Marcos Growers Wholesale Nursery in Santa Barbara carry this, but I am guessing that none of them do... Each will have a plethora of other similar species and hybrids, however, and give info on hardiness as well, and all but Sierra Azul's stock can be special ordered in by your favorite local nursery.

Yes, where the flowers lay along the stem on one side resembling a toothbrush they're referred to as 'toothbrush' grevilleas, but others are full flowers, lining both sides of the stem. b

Do you have a photo. If so post it here. What colour flowers and what shape, what kind of leaves, if you get on to the link below there are 50 pics there you may have some luck. I grow a few G.Banksii it has kind of ferny shaped silvery green leaves, G pteridifolia needle like leaves. Also G.baileyana with leaves so different and thicker from those two the undersides are brown when new.. Mary-Anne Here is a link that might be useful: Grevillea Gallery

You're having a bad time, aren't you Penny? Have you been fertilising? If you have been, stop it at once! As Mallee points out in reply to your banksia question, fertiliser can be poisonous to some natives, expecially those in the Proteaceae family, which include banksias, grevilleas and waratahs. Some people fertilise those plants with a special native fertiliser, which, if sparingly used, can hurry up young plants a bit. However there's no real need to fertilise native plants at all. If you have fertilised your potted grevillea it may be possible to flush some of the excess phosphorus out of the soil by lifting the pot so the water can run out the bottom easily, and then watering generously. Mallee's other point about poor quality water is another good one. Have you been using water polluted with detergent? If you are in a position to use rainwater only on your Proteaceae it's a good idea. Can you use bore or townwater where you are? If you are restricted to greywater, you could try keeping a jug beside the sink where you put the detergent-free water (such as the rinse-water from the teapot). Trish
