Good Together: Siberian Cow Parsnip, Purple Osmanthus, Chinese Tulip tree

Siberian cow parsnip is another of my garden's immense and dangerous plants, and shares with hardy orange the ability to send careless humans to the emergency room.

 

The danger with hardy orange is its thorns, which are long enough and sharp enough to stigmata a hand or puncture an eye. Siberian cow parsnip causes injury when chemicals that infuse all of its parts come into contact with skin. They bring on a dermatitis so severe—blisters! scars!—you'd wish it were just poison ivy.

Both plants have ornamental potential that's unique as well as substantial, so I grow them respectfully. I allow the cow parsnip to self-seed under careful supervision, so it can pop up with strategic spareness. This one volunteered in just the right place to partner with both purple osmanthus (front) and Chinese tulip tree (back).

 

The parnip's coolest connection to the two isn't the contrast with its immense jagged foliage. Nor with its satellite-sized umbels of white flowers held high out of frame. It's with those purple speckles.

Good Together: Mandarin Honeysuckle & Romantika Clematis

Spring into early summer is the year's first season of unstoppable garden color; fall foliage is the second. In between are the months of the year's hottest and driest weather, which make exuberant garden displays possible only by dint of creativity, wisdom, and industry.

 

But from now through early July, the living is still easy. Even extravagant moments, such as this tapestry of Mandarin honeysuckle and Romantika clematis, are a snap.

I planted both vines years ago and, so far this entire year, have done nothing to encourage let alone stage-manage their performance. Bountiful though they surely are, could the show possibly be better? Perhaps. Time for a closer look at what makes combinations of colorful plants exciting, both at first glance and upon sustained reflection.

The Best Season Ever: Chestnut Rose in Bloom

Chestnut rose is unique: Out of all the roses hardier than Zone 7, it alone becomes so large and woody that any one of its stems could be trained as a trunk, and that stem's branches the trunk's canopy. In other words, this is a "tree" rose can become a true tree.

Mine has been in training since being planted in 2000, and is mature enough to be self-supporting even though its canopy is now eleven feet wide. And, hey: it's a rose. How 'bout those flowers?

Today in the Garden of a Lifetime: Big-Root Geranium

No temperate garden should be without big-root geraniums. Of all the hardy geraniums with reputed groundcovering prowess, big-root is the most successful where summers can get into the nineties. No wonder: It's deer-proof, fairly shade-tolerant, weed-smothering, shrub-nuzzling, outward-flowing, immortal when happy, and madly floriferous as spring ripens into summer.

This is the white-flowered variety of my modest collection.The clump is four feet across and nearly ten years old. It receives no care at all. Geranium macrorrhizum is a snap to divide, so why haven't I spread this workhorse garden-wide? Time for a closer look.

Camperdown Elm in Full Foliage

Three weeks ago, this enormous weeping elm was in "full samara," meaning that its spring display of countless pale-green winged seeds—known as samaras—was at its height. Their countless fluffy clusters gave the whole tree the look of a giant ruffly hoop skirt. And I mean giant: I parked my boxy brown Jeep nearby for scale.

Now that the foliage has emerged, the tree looks like a huge haystack or some sort of unstoppable green monster that will sneak up on my car and demolish it. Monstrous or ruffly, old Camperdown elms are never less than impressive. They are automatically the hulking star of all the landscape within view. Here, even the purple beech across the street—normally a garden's pride and joy—is mere background.
