Keywords: Plant identification, Betula

PAL Question:

Are there any tree identification guides online? In particular, I am interested in weeping birch.

View Answer:

For several excellent images of weeping birch (Betula pendula), go to Oregon State University's landscape identification site at http://oregonstate.edu/dept/ldplants/ and click on Betula in the bright orange box.
Betula pendula is toward the bottom of the page.

Also try Virginia Tech's tree identification page.

Here are some other online tree identification guides:

Keywords: Silene, Plant identification

PAL Question:

I am having trouble growing Silene (do not know the species). It has magenta flowers with notched petals on two foot stems and hairy basal foliage. I have killed four plants that were planted in four different locations. I am able to keep hundreds of other plants alive in my garden, but not this one! It flowers profusely from mid April through July. Then the leaves start wilting, and before long, it is dead. The only thing I can think of is that it needs superior drainage. Could I be overwatering it?

View Answer:

You may have one of the annual types of Silene, which die after setting seed. It is really hard to know for sure since there are over 500 species. You may be able to identify your Silene in the book Lychnis and Silene in the Garden, by J.L. Jones, 1999.

There are some magenta-colored species of Silene with notched petals (Silene dioica and Silene hookeri for example), as you describe. These are alpine or rock garden plants that prefer well-drained conditions and do not like highly acidic soil. It is certainly possible that you have overwatered or that the soil in which they are planted doesn't drain sharply enough or is too acidic.

Keywords: Anaphalis margaritacea, Plant identification, Compositae (Daisy family), Botanical nomenclature

PAL Question:

I am doing some research on daisies. I have had trouble finding out what Amaranth daisy (Pearly Everlasting) looks like, and how to differentiate it from other daisies.

View Answer:

Pearly Everlasting is Anaphalis margaritacea, which is in the plant family Compositae (also called Asteraceae), according to David Mabberley's The Plant-Book (Cambridge University Press, 1997). Below are links to images and information about this plant.

The problem with common names like 'daisy' is that they may refer to a large number of different plants. 'Daisy' can refer to Bellis perennis, Gerbera jamesonii, Olearia species, Chrysanthemum coronarium, Felicia bergeriana, Leucanthemum vulgare, and many other disparate plants.

Below are web links to sites which may help you with plant identification. There are also many good books on the subject, and an excellent starting place is Roger Phillips and Martin Rix's The Botanical Garden (Firefly Books, 2002).

Keywords: Plant identification, Seedlings

PAL Question:

I have some seedlings coming up in my compost. They smell a bit like basil, but they could just as easily be weeds. I'd like to know if there are resources for identifying plants at this early stage of growth.

View Answer:

You could wait a week or two and allow the seedlings to develop, which might make identification a little easier. However, there are various resources online for identifying plants, especially weeds, at the cotyledon (seed leaf) stage.

There are also print resources which illustrate plants at the seedling stage:

  • Seeds of Woody Plants in North America by James A. and Cheryl G. Young (Dioscorides Press, 1992)
  • Woody Plant Seed Manual prepared by the Forest Service, USDA (1948), also available online
  • Seeds: The Ultimate Guide to Growing Vegetables, Herbs & Flowers by Sam Bittman (Bantam Books, 1989)
  • Park's Success with Seeds by Ann Reilly (Geo. W. Park Seed Co., 1978)
  • Park's Success with Herbs by Gertrude Foster and Rosemary Louden (Geo. W. Park Seed Co., 1980)
  • Weeds of the West edited by Tom Whitson (Western Society of Weed Science, 2000)
  • Weeds of California and Other Western States by Joseph DiTomaso and Evelyn Healy (University of California, 2007)
