Plants I'm Growing: First blooms—Yellow Daffodils, Rhododendron "Noyo Dream"

It's been warm lately for January here, but plants in the garden are starting to bloom pretty much on schedule—that is, in line with their typical bloom times. The first flowers on the Rhododendron "Noyo Dream" in the side yard opened on February 1. The first of the yellow daffodils in the front garden started to bloom on February 4. 

Plants I'm Growing: First Blooms--Pink Flowering Plum and "Noyo Dream" Rhododendron

I've been keeping track of the first flowering of many plants in the garden for about eight years now. I have analyzed the data to see if the flowering period of plants are shifting, which was my original intent in creating a kind of botanical calendar, but the Rhododendron "Noyo Dream" bloomed today, which seems very early. Usually this plant blooms in February or even early March. For example, "Noyo Dream" bloomed on February 25 in 2009, on February 7 in 2010, on February 2 in 2011, and March 2 in 2012.

On January 13, the first blossoms opened on the pink flowering plum alongside the house. Today both this plum and the white plum on the other side of the house are in full bloom and buzzing with bees.

Plants I'm Growing: First Blooms--Tulips, Daffodils, Fruit Trees, and Rhododendrons (Late February 2016)

A lot is going on in the garden at this time of year. Our two-toned daffodils bloomed on February 20. They're always a little later than the regular yellows daffodils. Our dwarf peach tree started blooming on February 15, the dwarf nectarine a day later. February 23 brought the first blooms on the last of the species tulips that have survived in the garden (many were eaten by ground squirrels, and the species tulips don't seem to live that long--nor do they spread much). They are a very cheery early spot of bright pink and yellow in the garden at this time of year. On the same day, the first flowered opened on the "Noyo Dream" Rhododendron on the side of the house—always the first rhododendron to bloom.

Plants I'm Growing: First Blooms--(March 2-4, 2012)

Sometimes it's hard to keep up with all the new plants coming into bloom in the garden. Today saw the first bud open on the pink species tulip (Tulipa bakeri) called "Lilac Wonder." The Santa Rosa plum I planted a couple of years ago as a pollinator for our pluots is now in full bloom. The first flower opened on March 1. The Rhododendron "Noyo Dream" is also in full bloom. The first flower opened on March 2.

The first Lilac Wonder tulip bloomed on March 15 in 2011, on February 24 in 2010, and on March 5 in 2009, so this seems a fairly typical date--about in the middle of the range. The plant has calculated years of 356 days, 384 days, and 355 days so far, which average to exactly 365 days.

The Santa Rosa plum bloomed on February 23 in 2010 and on February 16 in 2011, so March 1 seems comparatively late. So far, the tree has calculated years of  358 days and 379 days, which average to 368.5 days, still somewhat long, but there's not enough data yet for that to be very meaningful.

The Rhododendron "Noyo Dream" bloomed on February 25 in 2009, on February 7 in 2010, and on February 2 in 2011, so this this seems quite late this year. So far, the plant has calculated years of 347 days,  360 days, and 393 days. Despite the odd lengths, these three average to just under 167 days, or close to an actual year.

Plants I'm growing: First blooms--Rhododendron "Noyo Dream," Higanzakura Flowering Cherry

Our first rhododendron began to bloom today, the bright red one called "Noyo Dream," planted under the bird feeder (it fades to pink). Last year this plant bloomed on February 25--so the flowers opening today seems very early indeed. A year as calculated by this plant was thus only 347 days--the first real deviation from around 365 days of any of the plants I've been tracking. Perhaps it has bloomed early because of all the rain we've had this--or maybe it bloomed late last year, retarded by the drought.

The Japanese Higanzakura (a flowering cherry) appears to have started to bloom on the 5th. That, too is considerably earlier than last year. The plant bloomed in 2009 on February 20; a year according to this plant was therefore 350 days. Both photos are of the plants last year. None of the blossoms are so fully open yet.
