Whats blooming in the neighborhood?

All over the neighborhood new & beautiful things are starting to bloom! Here are some pictures I took this week:

I noticed this pretty tree while walking Pace...

Pace wanted a sniff!

This picture is from when we first got him 3 years ago.
I guess he has a thing for sniffing flowers :)

False Tarragon Conspiracy!

Much to my dismay I recently discovered that I had been sold Russian Tarragon. I was suspicious of my tarragon because I noticed that unlike my basil and chives, which had flavor from the time they were wee little sprouts, my tarragon tasted like nothing at all. I thought maybe it just needed some time to grow, so for the last several weeks I have nurtured and loved it along with my other plants. When it was about 5 inches tall and still had no flavor I started to get suspicious & turned to google for answers. This is where I discovered that there are two types of tarragon. The one we all know and love, French Tarragon, is a very finicky plant and does not seed or reproduce well. However, its flavorless but visually identical cousin, Russian Tarragon, seeds like a weed. So, when you buy seed packets of Tarragon, 99% of the time it's the wrong variety. Burpee doesn't care that it's selling you a weed, it's just happy to turn a profit. So this is my warning to anyone hoping to grow this herb at home. Only buy transplants, not seeds. Before you buy the transplant, tear a piece of the leaf off and taste it! If it tastes like nothing, don't buy it! My beautiful well loved little weeds ended up in the garbage. So sad.

RIP Russian Tarragon

Possible Edema on Tomatoes

I am having an unusual issue with some of my tomato plants. I have noticed some small spots showing up on the leaves that look like tiny blisters. After a few days the blisters get more numerous and eventually the leaf gets dry & crunchy and falls off. This problem seems to be specific to certain varieties of my tomatoes, and although they are all growing in close proximity it is not spreading. My first worry was that I had Septoria leaf spot or something similar to that, but when I started googling images of that it didn't look the same. I eventually found my way to some postings about Edema. In short, this is caused when the roots take up more water than the leaves can use, causing blisters on the leaves.

The most common cause of edema is the presence of abundant, warm soil water and a cool, moist atmosphere. Under these conditions the roots absorb water at a rate faster than is lost through transpiration. Excess water accumulates in the leaf, some parenchyma cells enlarge and block the stomatal openings through which water vapor is normally released from the plant; thereby contributing to further water retention in the leaf. If this condition persists, the enlarged cells divide, differentiate a cork cambium, and develop elongate cork cells externally to form a periderm. The rupture of the epidermis by the enlarged inner cells and the periderm account for the raised, crusty appearance of older edema spots."

So I have tried to cut back on my watering in hopes that things will get better. I also need to increase the amount of airflow around the plants. Now I am trying to find a medium between dry wilted plants and over watering... Wish me luck!

Can you see the small white spots?
The leaves at the tip have been more severely effected
and have started to dry out and curl.
Eventually they will fall off.
