SLOW SEED
Appreciated but not Touched
“Flower in the crannied wall, I pluck you out of the crannies, I hold you here, root and all, in my hand, Little flower . . . “ Whoa! Hold on there Lord Tennyson! Relax, little flower. I’m not doing any plucking.
I had hardly a hand in some of my best plantings, and that little flower is one of them.
There’s a small, moss-covered ledge at the base of the brick wall next to my front door, an east-facing spot that enjoys some morning sun in summer but shade from the nearby north wall the rest of the year. In short, it’s a perfect place for a summer vacation for my orchids, bonsai, and cyclamen.
Cyclamen flower in a crannied wall
The cyclamen is Cyclamen hederifolium, sometimes commonly called Persian violet (though a violet it is not; hence the need for botanical names). Although the flowers and leaves resemble those of the better known florist’s cyclamen (C. persicum), the two cyclamen species part company in some ways. Both the flowers and the leaves of Persian violet are much smaller than those of florist’s cyclamen, and the leaves of this diminutive species have decorative patterning. They resemble those of English ivy; hence the specific epithet “hederifolium.” Hedera is the botanical genus of English ivy. Flowers hover a few inches above the leaves on thin stalks, much like small, pink butterflies.
Best of all, Persian violet is cold-hardy where winter lows plummet as low as minus 20° F. Florist’s cyclamen must be grown as a houseplant.
Decades ago, I purchased seeds of Persian violet, and managed to raise a small stable of plants. They are ideal for naturalizing in partially shaded areas. While naturalizing the cyclamens seemed like a good idea, the dainty cyclamens would be gobbled up by the exuberant growth coaxed in the rich soil here. So my carefully nurtured cyclamens remained in their pots, wintering in a very cold spot in my basement and summering on that ledge near my front door.
Lo and behold, this year I’ve noticed two little plants that have seeded themselves in the bit of soil where the flagstone terrace butts up again the ledge. The effect is subtle, to say the least, but the flowers are all the more charming for their shyness. I can appreciate the second half of Lord Tennyson’s poem — “Little flower—but if I could understand, What you are, root and all, and all in all, I should know what God and man is” — but feel no need to, an aversion, in fact, to plucking the flower from its crannied wall.
Slow Cyclamen
Years ago, I learned three things about growing cyclamen from seed. Fresh seed is best. Keep the growing medium consistently cool and moist. Be patient; germination could take many weeks, and keep plants growing well for at least two years to allow the tuber to develop.
After that, plants can begin their spring dormancy, flowering and sprouting new leaves in late summer, the latter lasting well into winter, depending on temperatures.
Slow Ramps
Ramps (Allium tricoccum) are all the rage; here also, and my plan is to expand my ramp planting of two potted plants into a passel of ramps by growing them from seed. My experience in growing cyclamen from seed might come in handy here.
Although both plants enjoy similar growing condition, at least as far as the need for part shade in spring, the life cycle of ramps is different from cyclamens. Ramps sprout leaves in spring, send up a flower stalk, and then the leaves fade away as the plant goes dormant. The flowers talk remains, developing a head full of seeds — which I collected last week.
I planted the small seeds in potting soil in a flower pot. The journey begins. Those seeds could take anywhere from 6 to 18 months to sprout. When just ripe, ramp seeds have an under-developed embryo, a situation that inhibits germination. Keeping the seed warm and moist permits development of the embryo and, eventually, root growth.
Once root dormancy has been broken, there’s still shoot dormancy to contend with. Shoots won’t grow until the seeds, with their root sprouts, have experienced a period of cool, moist conditions — that is, they recognize that winter is over and it’s safe to send a green shoot aboveground.
If root dormancy isn’t completed before winter sets in, it has to finish the following year, with shoot dormancy needing fulfilling after that: 18 months after sowing. Fulfilling root dormancy before winter allows shoot growth the following spring: 6 months after sowing. I’m making sure of root dormancy being fulfilled before cold weather sets in by keeping the pot of seeds moist and in the greenhouse. Temperatures are cool in the greenhouse in winter, so I’m expecting — hoping — for sprouts to appear by late winter.
Growing ramps and cyclamen from seed is similar in that a prime ingredient for success is patience. In the case of ramps, if everything goes right, I could be harvesting my first home grown ramps in 5 to 7 years.
SUCCESSES, EDIBLE AND OTHERWISE
Stand Up Straight!
I am particularly proud of my Brussels sprouts this year — and I haven’t even tasted them yet. How odd that I should be proud of this vegetable that I spurned in the past, often quoting a friend who referred to them as “little green balls of death.” Then I put my own twist on that description, saying that perhaps the friend meant that Brussels sprouts were only palatable a “little boiled to death.”
I’ve come around, and decided, a couple of years ago, that Brussels sprouts were worth growing, despite their high demands on space and time. For good production in northern climates, the seeds need to be sown indoors in early March, and then harvest doesn’t start until October or sometime after the first frost. And for all that waiting, each plant — a mere single stalk with whorls of leaves from top to bottom and a sprout at the base of each leaf — takes up an area of about three feet by three feet.
Gustas Brussels sprouts, standing up straight.
Things would be bad enough if a Brussels sprouts plant just grew straight up to fill its allotted area. But the plant can’t support itself, so in its youth it flops down on the ground. Once that supine stem has created a firm base upon which to rise, the end of the growing stem curves more or less upward according to original plan. That youthful waywardness wastes and muddies lowermost sprouts, with the sprawling plant demanding even more space, which is a problem in an intensively-planted garden.
This summer, before the plants even had time to consider flopping down, I poked a bamboo pole into the ground next to each one, which I tied to the pole, adding ties to keep up with growth. Perhaps a bit too orderly for a vegetable garden, but my Brussels sprouts “trees,” each now over four feet tall, look quite attractive.
The “trees” are not likely to grow much higher because I pinched out the top bud of each plant in early September. This pinching redirects the plants energy from the highest growing point to the side shoots — which are the sprouts. All month, the sprouts have been fattening, soon to be snapped off and eaten.
Not Your Average Marigold
I also count among this season’s successes two little-known flowers, both of which elicited “oohs and ahhs” from visitors here. One of the flowers were Signet marigolds. You might think, marigolds?, they’re okay, but more “ho hum” than “ooh and ahh.” Not so.
Signet marigolds, Tagetes tenuifolia, are a different species from common marigolds, and they look a little different. Mostly, they’re smaller, expanding into amorphous mounds of fine, lacy, lime-green leaves, from which stare out small yellow or orange blossoms — most charming. A lemony-marigold aroma wafts from both the blossoms and the leaves.
Actually, the aroma can waft over the whole garden if you plant enough Signet marigolds — which I did this year. In the past, the seeds never germinated very well for me, so I just spot planted what few seedlings I could raise here and there in the garden.
This spring, in mid-April, I sowed the seeds densely in an 8 by 6 inch seed flat. The dense planting led to an excessive number of crowded seedlings. While they were still young, I gently lifted each one to transplant into its own potting-soil-filled cell to grow for a month or so before planting out in the garden.
The few plants I poked in at the feet of vegetable beds on either side of the main path through the vegetable garden have grown into sprawling mounds that wash into the main and side paths of the vegetable garden like seawater into an undulating beach. The flowing mounds effectively soften any excessive orderliness of the garden — from the soldier-straight Brussels sprouts plants, for example.
A Cardinal in our Midst
My grape arbor creates a horizontal roof nine feet above my terrace. Each of the four grape vines rises to that height on a single trunk. What an opportunity for a climbing vine, especially one that climbs by twining! My other floral success this year has been with such a twining plant, cardinal climber (Ipomoea x multifida, a hybrid created by mating I. coccinea and I. quamoclit).
In the past, other species of Ipomoea climbed those trunks. Morning glory was one, but that only blooms, of course, in the morning. Moonflowers have also dressed up the trunks, but they bloom only at night.
So this year, cardinal climber was the Impomoea species for the grape trunks. It blooms all day long, clothing itself in blossoms from top to bottom. The size and color of the blossoms, an inch or so across and cardinal red, seem best for relatively close viewing when sitting on the terrace.
No need for these flowers to soften any excessive orderliness of the arbor. The grape trunks wend their way skyward and their long, new shoots create plenty of disarray except right after they are pruned each spring.
VEGETABLE GARDEN FRUITS
End of Summer But I Still Need some Watermelon
Given sun, heat, and reasonably moist, fertile soil, watermelons are easy to grow. The greater challenge is in harvesting them at their peak of perfection. Even professionals sometimes fall short, as witnessed by not-quite-ripe watermelons I “harvested” awhile ago from a supermarket shelf and, a couple of weeks later, from a table at a local farmers’ market.
That was while I was waiting for my own watermelons to ripen — the delectable variety Blacktail Mountain. But should I have been waiting?
All sorts of indicators are touted for telling when a watermelon is ripe. The part of the melon laying on the ground supposedly turns yellow. The tendril opposite where the melon in question is attached dries up. Or my favorite method: thumping. Knock you knuckles on your forehead, your chest, and your stomach. The sound of a ripe watermelon should match the sound of the chest thump. The forehead sound indicates that the melon is underripe; the stomach thump, overripe.
Watermelon, it was ripe & delicious
Sure, one could pull out the bells and whistles. As I wrote, even professionals have problems determining watermelon ripeness. To aid in commercial harvesting, nuclear magnetic resonance, one possibility, was considered — at $60,000 to $1,000,000 — out of budget. Acoustic resonance testing ($950) was a more viable alternative, but still not for me, with my five plants.
After my two disappointing purchases, my mouth was watering for my own melons. I ignored the question mark hovering in air above the largest of the lot and, despite its lack of a dried tendril, a yellow bottom, or a telltale thump, cut it from the plant. Long story short: It was delicious, perhaps just a tad overripe.
What about the other waiting melons? I’m just going to harvest them, as needed, and hope for the best.
Update: I may have one more addition to the imperfect list of watermelon ripeness indicators. It seems that ripe melons might develop a whitish, waxy “bloom” on their skins.
Update on the update: Scrap that way bloom indicator. Or, it might be part of the picture. Now I look for a number of indicators, and if some indicate ripeness — I thump the melon before picking.
Next Year: More Watermelon Plants
Part of the watermelon problem is that I don’t grow enough watermelons. I once lived and gardened in southern Delaware, a few miles from one of the epicenters of watermelon production. With ideal climate and soil (sandy), I grew an abundance of large watermelons. Whether or not a single melon was picked underripe was not so critical. Once ripening began, any unripe ones could be relegated to the compost pile; a better one was always in the offing.
My Favorite Vegetable (Fruit?)?
Like watermelons, sweet corn is also easy to grow. It can get by with less heat than watermelon, but demands a more fertile soil. Harvesting sweet corn at its peak of perfection also can be a challenge, though not nearly the challenge of watermelon. Picked too soon, corn is tasteless and toothless; picked too late, and it’s too starchy and toothy, a delight for animals, excepting humans.
The first hint as to when I get to pick corn is when tassels atop the stalks begin to shed pollen grains — millions per tassel!
Corn, testing for ripeness
About three weeks later, I start peering into the corn bed to look at the silks spewing out the ends of each ear. Silks are more or less dry on a ripe ear. At that point, I can usually tell ripeness by just wrapping my hand around the ear to feel its fullness, although less than perfect pollination can drain the bulk of a ripe ear so it feels underripe. (It’s hard to imagine less than perfect pollination when you consider that each tassel sheds literally millions of pollen grains; then again, each grain remains viable for only a few minutes; then again, again, it can travel hundreds of feet in that few minutes; then again, again, again, each kernel only develops if a pollen grain lands on a germinates on the single silk to which it is attached.)
Any doubt about ripeness, and it can be confirmed before committing to harvest by peeling back the husk just enough to see some kernels. Their color and plumpness might be a giveaway. If not, a thumbnail pressed into a kernel should yield a milky fluid.
Sweet corn, in contrast to watermelon, is easy to produce in quantity, even in a relatively small garden. So tasting an ear is no great sacrifice; there’s plenty more.
Hybrid varieties of corn tend to ripen uniformly, so once one ear in a bed is ripe, the whole bed is likely also ready for harvest. A bed of a non-hybrid variety requires more frequent assessment and harvesting, which is better for home use where you might want a few ears each day or so, rather than a once-over harvest. With successive planting and selective harvesting, we’ve been enjoying sweet corn almost daily since the end of July.
