Vines

Though “clinging” and “vine” seem like a wedded concept, only a few vines really do hold on that way, using aerial rootlets that act as suction cups to attach themselves to their support. These rootlets are very strong and enable even very heavy vines to rise high on flat walls. Examples include climbing hydrangea, Boston ivy, and English ivy.

More commonly, vines are inclined to twine, wrapping their main stems around the nearest available support and circling it as they grow. Examples include beans, morning glories, bougainvillea, hops, hoya, and wisteria.

The other large group are tendril-climbers, which send out specialized, leafless stems

that wrap tightly around any adjacent object that’s thin enough to get a grip on. Examples include peas, cup-and-saucer vine, grapes, passionflower, and porcelain vine. The specialized stems that do the holding on can also have leaves, in which case they’re called petioles. Clematis are the best known petiole users, but Climbing Snapdragons (asarinas) also climb this way, and so do those rare nasturtiums that genuinely climb.

My trumpet vine last fall climbing over the arbor. It pretty much goes where it wants to and requires a firm hand.

But not all vines do genuinely climb. Some just head for something supportive and grow on, around, over, or through it, sending out a tendril or two, applying a rootlet, or twining a bit without behaving in and recognizably organized way. Expect to receive some guidance if you plant these and have a particular direction of growth in mind. Examples include trumpet vine, silver-lace vine, and some of the jasmines.

House of Flowers

db0d06842a922723a63238991937df5dA fun project to do with your children or grandchildren: make a house of sunflowers and morning glories.

Sunflower houses are not an exact science, which is a great part of their charm. All you need are the flower seeds and a patch of open ground that gets plenty of sunshine.

Choose a sunflower that grows tall but also makes some branches, rather than an old-fashioned type that goes straight up and then hangs its heavy head. ‘Giant Sungold’, ‘Soroya,’ and the pale-flowered ‘Moonwalker’ are good choices. Make sure the morning glories are the climbing sort; it’s hard to beat good old ‘Heavenly Blue’ in this situation.

Wearing gloves, use agricultural lime to draw the shape of your house on the grass. (Don’t make it too small. When the plants are full grown, the walls will be about 3 feet thick.) Following the line, remove a foot-wide strip of sod. Enrich the exposed soil with some compost and well-rotted manure.

After all danger of frost is past, plant sunflowers about 3 feet apart, arranging a triangle of seeds at each location and spacing the seeds in the triangle about 2 inches apart. (Don’t forget to leave space for the door!)

When the sunflowers have four leaves, cut off the weaker extras. You should now have single, strong plants, spaced evenly around your perimeter. Wait until they’re 2 feet tall, then plant morning glories every 4 inches or so in the spaces between them. When the vines sprout, use thin twigs to train them toward the sunflowers.

Resist the temptation to fertilize. Sunflowers that grow tall too quickly are prone to falling over; and morning glories that get lots to eat make leaves instead of flowers.
