A Case of Mistaken Identity

When asked for input about trees, I generally respond that "I'm not a tree person," an inept way to explain that I'm not particularly knowledgeable about trees.  I grew up surrounded by palm trees and a few fruit trees but the prominence of trees in the gardens of my childhood diminished as residential lots shrank and the area in which I grew up developed, with roads and commercial buildings gradually replacing ranches and orchards.  The first garden of my own, a jungle in some people's views, contained just 3 trees, a birch, a Japanese maple, and an Arbutus unedo.  In contrast, the garden I inherited at the end of 2010, contains more than a dozen trees, most of which I'd had no prior experience in growing.  This is a very long-winded way of explaining that I've been entirely wrong about the identity of one variety of these trees.  The tree I'd believed was a California pepper (Schinus molle) is, most probably, an Australian willow (Geijera parviflora).

How did I mistake the two?  I can't really explain it, except to say that Schinus molle is far more common in the general area in which I live.  Many of the pictures posted on-line as S. molle also look similar, at least from a distance, to those growing in my garden.  (See the images of S. molle posted here and here.)  Moreover, the only Australian willow I knew of, Agonis flexuosa, looks nothing like my trees.  There are some similarities between S. molle and G. parviflora.  Both have limited water needs, have pendulous branchlets, and produce cream-colored flowers in spring.  However, their bark and trunks are very different and, after seeing a mature California pepper at a botanic garden, I realized I was probably off-base in identifying my trees as S. molle.  After seeing drawings of the leaves of both trees in a recently acquired book, I was certain of my error.

I've yet to see G. parviflora in either a nursery or a botanic garden so I'm hesitant to be definitive about my trees' identity, although I can say with a degree of certainty that they aren't S. molle.  For one thing, the scattering of red berries characteristic of the California pepper tree during the summer months aren't evident on any of my trees.

The good news in the discovery of the classification error is that, of the two, G. parviflora is the more well-behaved tree.  The Sunset Western Garden Book says that it "combines the grace of a willow with the toughness of a eucalyptus."  Unlike the California pepper tree, its roots aren't invasive and it produces minimal litter (discounting that created by the local crows when they pull pieces of the tree out for use as nesting material).  It also isn't known to be susceptible to scale infestations and root rot like the pepper.  So, while I'm embarrassed by my mistake in identifying the trees, I'm gratified that the trees I have are unlikely to present significant difficulties for me.  I trust that they'll take no notice of my temporary failure to recognize their true nature.

Happy first day of summer to all of you in the northern hemisphere!  I hope the new season brings only pleasant surprises.

UPDATE: Based on comments provided by Max below and examination of additional on-line photos, it appears that these trees are Agonis flexuosa after all.

  2. Neither of the trees you mention are familiar to me; both sound very exotic. It is always nice to discover something is a better specimen than one had thought.

    1. I'm chagrined by my failure to recognize that the tree isn't a California pepper but I'm very glad to discover it doesn't have that tree's negative aspects.

  3. I've noticed Geijeras have leaves clustered in threes. Also, they are in the rue family and have numerous small flowers. The flowers pictured look like Agonis (myrtle family) flowers to me. I love getting my plant geek on. Great party trick.

    1. I think you may be right about the classification of my trees, Max. Although I've grown Agonis flexuosa before ('After Dark' and 'Nana'), I've never seen it flower. The flowers on my trees DO look to be more like those depicted in on-line photos of the peppermint tree than the flowers depicted on Geijera parviflora. Thanks!

    2. Agonis is a really nice tree. Especially the dark form. SO wish we could grow it here in Nor Cal!

  4. Good to know I'm not the only one who isn't up to speed on her tree indentification.

    1. And, as indicated in the exchange above, I'm still getting educated, Loree. Max is right that the flowers on my trees bear more resemblance to Agonis flexuosa peppermint tree than to those borne on Geijera parviflora. It's a good thing I usually record the classifications of the plants I buy!

  5. You have a gem instead of a thug! Is that good, or what?
