March 8, 2012: Springwater Trail betwen Linneman Junction and Powell Butte. The non-native common filbert (Corylus avellana) are noticeably fading out of bloom (although a few female flowers are still going strong). The native California hazelnuts (Corylus cornuta var. californica) with blooming male catkins and female flowers are much more common now. Numerous male catkins of red alder (Alnus rubra) were also observed in bloom today with a few female flowers visible. The flowers of osoberry (Oemleria cerasiformis) are now opening everywhere along the trail. The leaf buds of red elderberry (Sambucus racemosa) have opened with leaves several inches long and a few have the flower buds visible. The flower and leaf buds of red-flowering currant (Ribes sanguineum) are now enlarged and should be opening soon.

February 22, 2012: Springwater Trail at Powell Butte, west of Gresham, Oregon. The first female flowers of the native California hazelnut (Corylus cornuta var. californica) were observed in bloom today. A few non-native common filbert (Corylus avellana) are still in bloom although they are noticeably fading out of bloom. This overlap in bloom period means there could be a chance both species could form hybrid offspring.

February 18, 2012: Springwater Trail east of Main City Park in Gresham. The non-native common filbert (Corylus avellana) are noticeably fading out of bloom (although a few are still just starting). The native California hazelnuts (Corylus cornuta var. californica) with blooming male catkins are much more common although no female flowers have been observed. Numerous Scouler's willows (Salix scouleriana) were observed with the pussy willows (male catkins) beginning to bloom. The yellow spathes of several skunk cabbage (Lysichiton americanus) were also observed. The buds of many osoberry (Oemleria cerasiformis) are opening everywhere along the trail. No observable leaves or flowers yet. In addition, the leaf buds of red elderberry (Sambucus racemosa), black cottonwood (Populus trichocarpa), and bigleaf maple (Acer macrophyllum) are swelling and in some cases, can be noticed even from a distance.

February 12, 2012: Springwater Trail between Linneman Junction and Powell Butte. The male flowers of the non-native common filbert (Corylus avellana) are now in fading out of bloom. The first native California hazelnuts (Corylus cornuta var. californica) with blooming male catkins have been observed blooming in sunny locations. The first male catkins of red alder (Alnus rubra) were also observed in bloom today. I will get and post photos of both the male and female flowers later in February as more come into bloom. A few Scouler's willows (Salix scouleriana) were observed with pussy willows (male catkins) today.

February 3, 2012: Springwater Trail between Gresham, OR and Boring, OR. The female flowers of the non-native common filbert (Corylus avellana) are now in full bloom. A few native California hazelnuts (Corylus cornuta var. californica) with male catkins forming have also been observed in sunny locations. No blooms on the latter yet.

January 16, 2012: Springwater Trail east of Main City Park in Gresham. The male catkins of the non-native common filbert (Corylus avellana) are now in full bloom. No sign of female flowers yet. A skunk cabbage (Lysichiton americanus) with leaves about one foot high was observed. No spathe yet.

January 6, 2012: Springwater Trail near Gresham, OR. The male catkins of the non-native common filbert (Corylus avellana) are now beginning to bloom.

January 1, 2012: Springwater Trail near Gresham, OR. The male catkins of the non-native common filbert (Corylus avellana) are well-formed and should be blooming in the next few days.
