bloom depend on various factors including temperature, cloudiness
or the flip-side degree days, late season snow pack, and elevation.
For example, compare the Anemone (5/8/99)
which was observed
slightly above sea level and Anemone (6/27/99)
which was seen at over 3,000 feet elevation. Difference of six weeks
in blooming dates. Sometimes the same flowers, such as the Anemone,
can be seen at low elevations as well as in the mountains. Other
flowers are only found at lower elevations or at higher elevations.
Some are very common and considered weeds (Cow
Parsnip, 7/1/99 for instance), no one gives them a second look.
Others seem to be exceptional, such as the Chocolate
Lily. Some wildflowers cross the line between wild and domestic
and find their way into the Perennial
Garden. These can be excellent choices for gardeners looking
for hardy plants and some nurseries sell these hardy perennials.
