Perhaps everyone is dying to know which color seed produced which color pattypan squash. Well, perhaps not. But I know I am.

As some may recall, we started the pattypans rather late in the season with a packet of seeds we picked up at Adams Fairacre Farms (see May 9, 2014). The variety was labeled “Tricolor” and to be helpful, the producer dyed a third of the seeds red and another third green. Whether the dye choices are some kind of homage to the Italian flag was not immediately apparent.

Presumably, the tricolored seeds are to tell the tricolored squash apart. Unfortunately, the seed producer did not provide a key. Almost entirely arbitrarily, I mapped buff (undyed) seeds to white pattypan squash, the green seeds to green squash (how’s that for going out on a limb?), and, by process of elimination, the red seeds to yellow fruit.

The last pairing was the least obvious choice because red is not a color usually associated with summer squash. Also, one could argue that the buff-colored seeds are a variation on yellow and, hence, should produce yellow fruit. However, I did say my choices were mostly arbitrary.

Thinking ahead, I labeled each pot in which I sowed a pattypan seed with the seed color which it contained (see May 26, 2014) and then, when setting the seedlings out, drew a sketch to keep track of where each seedling was planted (see June 8, 2014, part 2). I wanted no ambiguity.

So, now that the squash vines are starting to bear fruit, I have my answers. And—(drum roll)—it turns out my carefully formulated hypotheses (by which I mean my guesses) were correct.

Well, two out of three, anyway. A red seed did, in fact, produce a plant bearing yellow pattypan squash and a green seed did actually produce a plant bearing green ones (we ended up with only one vine of each color). Sadly, though, the plant that sprang from a buff-colored seed is not looking well and will not likely survive.

It’s probably safe to assume (if that is not an oxymoron) that the third plant, grown from the buff seed, would have produced a white pattypan squash (and too bad that we didn’t get any; white squash would look cool). But confirmation will have to wait until next year.

At last, time to set out the vegetable seedlings (and, at last, time to blog about it). We’re two weeks later than usual (we’ve set out on Memorial Day each of the last three years), mainly due to lingering cool weather.

And it’s more than a little ironic, considering that we sowed seeds for some of the vegetables much earlier than usual. Germinated indoors and then coddled during their early weeks with 16 hours of light per day and continuous heat, the tomatoes, eggplant, bell peppers, summer squash and cucumbers should have been raring to get outdoors a long time ago.

Yet somehow, they knew. They knew that indoors was much nicer, especially at night. I can’t say that I blame them. I wasn’t ready to spend much time outdoors until just recently.

To prepare for the seedlings, I first weeded the beds (see June 8, 2014) and then installed cages for the tomatoes. As in prior years, we’ll have a row of six cages along the north side of the planter; this year, the west planter is up in the rotation. In a departure from past seasons, however, we will plant only one seedling per cage.

To increase our tomato yield, we will also plant another six seedlings in the mounds at ground level, where the squashes mostly thrived last year. In May, we prepped the old mounds by adding fresh soil and mulch (see May 11, 2014). Today, we installed three cages. This exhausted the supply on hand and we will have to make a trip to the garden center for another three (we have some time before the tomatoes will actually need them).

We have four varieties of tomato—Sungold, Black Cherry, Yellow Brandywine and Country Taste Beefsteak—but unequal numbers of each. Because the west planter should be the safest (we’ve spotted evidence of moles or gophers this year; see June 1, 2014), we planted two each there of our favorites, the Sungold and Country Taste. One Yellow Brandywine and one Black Cherry filled out the row.

That left one Sungold, two Yellow Brandywine and three Black Cherry plants in the ground. It will be interesting to see which vines do better, those at ground level or those elevated in the planter. My money is on the planter.

After getting the tomato seedlings transplanted—buried up to their first branches to promote root growth—we moved on to the summer squashes. We set out two Supersett Yellow Crookneck, one Cavili zucchini (the only seedling that germinated) and three pattypans, one of each color (at least, I presume). I noted the location of the plant from each seed color so that we can confirm the color mapping (see May 26, 2014).

When we finished (at about two in the afternoon), the day had turned quite warm and it was time for a swim.

I’ve been neglecting my tomatoes, poor things.

While I potted up the squash and cucumbers almost as soon as they germinated, I’ve left the tomato seedlings in their seed trays for a month since they sprouted. True, the tomatoes are not as big—especially compared to the exuberant summer squashes—but they would benefit from a move into larger pots. There is not much room in the seed tray compartments for an expansive root system.

After taking care of the tomatoes, I moved on to the last of this year’s indoor sowing. We are determined to have a second color of bell pepper and picked up seeds for a yellow variety: Yellow Belle. With a name like that, I’m expecting demure flowers and beautiful fruit (with, perhaps, assertive flavor).

While at the garden center, we also purchased seeds for Early Fortune cucumbers, whose name implies bounty and punctuality (but whose number of days to maturity is larger than our previous varieties), and Tricolor Pattypan squash, whose name is, well, self-explanatory. I’m looking forward to growing these because it is my favorite type (and shape) of summer squash.

The producer of the squash seeds—Renee’s Seeds—thoughtfully color-coded them to differentiate the fruit that the plants will produce. Most of the seeds are buff; others have been tinted with red or green dye in shades reminiscent of the Italian flag. Based on the drawing on the seed packet, the squash will be either green, yellow, or white so the mapping is not immediately apparent.

Presumably, buff seeds will produce white squash, green seeds will lead to green squash, and (by process of elimination) red seeds will beget yellow squash. I planted two of each and will keep track of which ones ultimately bear fruit. That will be the only way to know for sure.

While preparing a seed tray for the peppers, cucumbers and squash, I was reminded that one must not lose faith. The seed tray was left over from last week’s potting up session (see May 3, 2014) and had been left sitting unwatered and unheated on a shelf of the seed-starting apparatus. Just as I was about to dump out the leftover soil, I noticed that another pickling cucumber seedling had emerged.

Because only one had sprouted previously, I quickly moved the second one into a larger plastic pot. I had given up on the cucumbers but at least one of them had not given up on me. Now was that a lack of faith on my part…or neglect?

Last Saturday, Rachel and I made an early spring visit to Stonecrop Gardens (see March 22, 2014). The Open House being celebrated that day focused on their indoor collection, which is extensive, if not encyclopedic; much more than can be described in the average 500-word blog post. In fact, at the end of the last account, having finished our snack (cookies and cocoa) we realized that we were only about halfway through the list of plants on display.

What remained to view (not counting the outdoor areas still covered by snow and ice) were the Alpine House, the End House and the Pit House. Of these, my favorite is the Pit House, and not just for the flowering bulbs and succulents that inhabit it. Architecturally, it is unlike any other greenhouse I have seen.

A long, narrow building, its floor is set into the ground by about two feet; stone steps at each end lead down to its central aisle. The tops of the planting beds along either side are at grade level so all of the soil is essentially subterranean. The gabled glass roof springs from short masonry walls that extend about two feet above grade.

The peak of the roof—this is my favorite detail—is supported by two parallel lines of steel wide flange beams that are aligned with the fronts of the planters, thereby maximizing headroom over the aisle. Structurally, the Pit House is quite elegant (and that’s the nicest thing that I, as a structural engineer, can say about it).

Despite its partial embedment in the earth and glazed roof, the Pit House is not particularly warm inside. Nonetheless, it is cozy, mainly due to its diminutive scale. It feels not unlike a child’s playhouse although clearly, serious work is going on in there.

The beds are literally overflowing with a densely-planted collection of ranunculus, fritillaria, narcissus, primula, cyclamen and helleborus, to name just a few. Although only about a third of the area of the Conservatory, the Pit House contains two-thirds the number of different plants.

We strolled leisurely from one end to the other, enjoying the colorful blossoms that sprang from the garden beds at waist level or trailed along the steel beams over our heads. We left with an infusion of spring spirit and a renewed enthusiasm to get to work in our own garden.

I’m still going through the process of evaluating last year’s plantings to determine what will go into the garden this year.  Last time (see January 15, 2014), I used three criteria:  how much we liked the vegetable; how well it grew; and, if not well, what could be done about it.  So far, I have concluded that all of the cucurbits—summer and winter squashes; cucumbers—are loved, grew reasonably well (with exceptions) and can be encouraged to grow better.

What else did we grow?  Well, lots of root vegetables.  And, I should point out, lots of root vegetable greens.  The radishes, carrots, beets and turnips all sprouted quickly and then produced a full crop of verdant leaves.  This was not at all a bad thing because I have come to enjoy the greens almost more than the roots that generate them.  Whether plucked from the garden early (as part of the thinning process) and thrown into a salad or clipped from the mature roots and sautéed, they are a delicious addition to the table.

Sadly, the roots took a lot longer to develop, if they did at all, and their eventual success was varied.  The radishes did particularly poorly with the first and second plantings yielding a root only about half of the time while the third planting never really reached maturity.  The carrots and beets performed moderately better but were painfully slow (especially the carrots) to ripen.  I don’t think any of them got as big as they could have.  The turnips were the top performers and provided both sizeable roots and plentiful greens through most of the summer.

I think we’ll give them all another chance this year (we still have plenty of seeds) but will make sure to limit their Nitrogen, by which I mean that I will not add any to the soil.  That means using fertilizers that do not contain it (i.e., those with zero as the first number in their N-P-K rating).  I will have to do some research into what might work best but that’s a topic for a future post.

I would prefer to limit the colors of the radishes and the carrots because we found that the purple varieties were the tastiest (I guess I like the flavor of anthocyanins; see October 20, 2013), followed by the red.  However, that would be difficult without buying new seed.  Our current radish and carrot seeds are “rainbow” mixtures and there is no way to determine the root color from the seed’s appearance.  I suppose this is one good reason not to buy seed mixes.

Five of the six tomato varieties we planted last year passed the taste test and for the most part, all of them performed well.  We’ll replant the Country Taste Beefsteak, the Brandywine (although, perhaps, only the yellow), the Black Cherry, and the ever-popular Sungold but we’ll skip the Aunt Ruby’s German Green.  Therefore, we’ll have room for some new varieties.

And speaking of room, I think we will give each tomato plant a bit more this year.  Pruning remains a critical factor for tomato plants and the lack of space (due to the vines’ exuberant growth) compounds the issue.  The first year we gardened, we pruned too little; the next year, we pruned too much.  We’d hoped that last year would be just right and, in the beginning of the season, it was.  But then, at the peak of the summer, the tomatoes’ rapid growth overwhelmed us.

This year, we’ll plant one tomato seedling per cage and keep a closer eye on them.  Each plant will have more space to spread into and will have less impact on its neighbors.  With luck and careful pruning, each vine will remain within the confines of its own cage and will wrap around it rather than spill over the top.

Keeping the tomato plants separate will be also important to prevent the spread of blight which, having made an unwelcome appearance last year, is likely to return this year.  Once it arrived (on the Brandywine or Black Cherry vines), the blight quickly spread to the other plants.

The only vines that did not contract the disease were the Country Taste Beefsteak, which is another reason to replant them.  Even though the beefsteaks were infected by some other disorder (Septoria leaf spot?), it did not really affect their output.  Spraying everything with a bicarbonate of soda solution should also help.

While we were visiting a friend in his home (lucky us, he had invited us for one of his fantastic brunches), he asked about the purple string beans:  Do they, he wondered, taste any different from the green ones?

It is a good question.  Purple is an unusual color in the vegetable garden, second only to blue in rarity (is there any blue comestible other than blueberries?).  And while color is not always an indicator of flavor—the taste of red and green apples is not that different, for instance—it can be, especially when the color difference is due to ripeness, or lack thereof.

The answer to our friend’s question, though, is:  No; the purple string beans taste more or less the same as do the green ones.  In fact, as the beans cook, the purple fades away, leaving only the familiar green tint.  This is because heat and loss of acidity (due to dilution in neutral water) break down the anthocyanins that produce the color purple.  Chlorophyll, the green pigment (and component of photosynthesis), is apparently more stable.  (If we grow the purple string beans again next year—which is likely—I might try cooking a batch in vinegar or lemon juice to see whether that preserves the purple color.)

That matter resolved, I’ll ask my own follow-up questions:  What about the other vegetables growing in our garden?  Does their color dictate the flavor?

Well, as an indicator of ripeness, sure.  An unripe green tomato has a vastly different taste compared to a ripe red one.  We don’t grow them here, but apples (and most other fruits) exhibit this property.  It should be noted, however, that not all vegetables change color as they ripen.  Eggplant, for instance, starts purple and stays purple throughout its growth (and even its blossoms are tinged with purple).

But what about different colors of ripe tomato?  Do the yellow and orange varieties have a different flavor from the traditional red ones?  How about tomatoes that are green when ripe?  Furthermore, are the differences in flavor, if any, due to the color or is the color just an indicator of the difference?

Answering the last question first, I think the color is merely an indicator of a difference in flavor and not the cause of it.  The various colors of tomato do have varying flavors but the variations are due to different levels of sugar and acidity.  And as noted above, pigments react very differently to acidity.  Typical red tomatoes are relatively high in acidity so acid-resistant pigments like carotenoids (of which lycopene is the most common in tomatoes) will dominate their color.

At the other end of the spectrum (in both flavor and color), orange, yellow, green and purple (sometimes referred to as black) tomatoes are sweeter in flavor, a result of their being lower in acid.  Another consequence of higher pH is that pigments less resistant to acid, such as the anthocyanins, can survive in their colored state and contribute to the tomatoes their distinctive hues.  In other words, the pigments act as a natural litmus test to visually signify flavor.

This is only a quasi-scientific analysis but it makes sense, at least for the tomatoes.  In addition to the tomatoes, we also planted different colors of carrots, radishes, beets and bell peppers this year.  To my taste buds, the red and white-striped Chioggia beets tasted the same as the Touchstone Gold and neither tasted any different from the typical all-red variety.

Similarly, there was only one significant difference between the taste of our Quadrato d’Asti Rosso (red) and Orange Sun (guess) bell peppers and the common green variety.  The peppers we grew tasted less grassy, a flavor component that I can only call “green”.  This is a good thing because that grassiness usually puts me off bell peppers.

Our radish crop was not sufficiently successful to make an assessment of their flavors but the carrots, which flourished a wide rainbow of colors, also yielded an array of flavors.  The orange were the most typical (no surprise there) while the yellow and white were woodier and the purple were sweeter.  The range in flavor was not quite as great as in color or as stark as with the tomatoes but there was definitely a correlation.
