ForageSF by Jaymi Heimbuch
What does one do if one does not know the name of a plant that has no label or tag on it?
Two friends came to me this week with just such a request. I am pretty good at identifying plants that grow in my temperature zone 6 and try to recall the Latin name as well as the various common names of these plants. I also pride myself on being able to identify many of the native wild flowers or plants in my area. But there are so many flowering plants in the world, that it is impossible for any person to be able to name them all.
For a scientific account on the number of plants in the world, you can read this article. One of the sources I use says it lists 15,000 ornamental plants in the book. So though I know a number of tropical plants or plants that grow in different temperature growing zones, there are too many for me to really know. But when friends come to me and ask me to identify a plant, I am challenged. Then I am like a bulldog with a meat bone tenaciously trying to find the name of the plant in question.
tibouchina urvilleana by nestmaker
This week one plant that was fairly easy for me to identify was the Tibouchina urvillieana- Princess flower or glory bush because I had seen it before. See here. This gorgeous flower is a native of Brazil but is a noxious weed in Hawaii. In our temperature zone 6 it has to be taken in for the cold weather because frost will kill it. It will grow in zones 9-11 and perhaps zone 8. If grown indoors, grow Tibouchina in a soil-based potting mix in full light with shade from the hot sun. During the growing season water it freely and feed it a balanced liquid fertilizer monthly but water sparingly in the winter. If you grow it outdoors, grow it in moist fertile soil in the full sun.
