One of the mystifyingly unheralded plants in my garden is the clematis. Aside from a sweet Autumn clematis that covers an arbor in the side yard, I never quite give them the love they deserve, the fault of which lays entirely at my feet (in the shade) in spite of the fact that they continually give good face (in the sun). This purple version sits on the other side of the arbor, where I plopped it mainly as an afterthought, yet here it is, brightening its little corner, blooming at the top of the adjoining fence, and valiantly performing despite my neglect. This year, I may have to work to make some amends.

Pruning is the tricky part of caring for the clematis vine. To be honest, aside from the sweet Autumn version and the common purple Jackmanii variety (both of which perform best when cut down to a foot in the earliest spring, before new growth starts), I don’t know enough to say anything on the basic pruning of the other forms. If you don’t know, ask for instructions or research which variety you have to determine a pruning schedule, as that is the key to getting them to bloom properly. (It’s also one of the reasons I’ve avoided them; easy upkeep is the way I try to operate in the garden.) There are beautiful flowers on some of them, though, so I may have to put in the effort one of these days to figure it out. ‘Nelly Moser’ in particular looks especially lovely, and with a name like Nelly, what on earth has taken me so long?

One of the more graceful plants in the garden right now is this peach-tinted tree peony. Its blooms are huge – dinner-plate-dahlia-sized when they reach their full potential – and their journey is remarkable. It begins in the tight swelling of its almost silvery bud. The bud gets larger and larger, eventually (and this is the plant’s one major drawback) getting too top-heavy to stand up straight, drooping and nodding and dangling its heavy load at the end of the branch. By the time it starts to open, it is usually facing the ground, and hanging well below the finely-cut foliage. For this reason, I often end up cutting the stems and bringing them inside. This is when the magic begins, and it’s fascinating to watch up close.

It opens the size of an average peony, staking its salient claim by way of its unique fragrance. This isn’t the sweet scent of the old-fashioned peony – this is one spicy electric jolt, with a heady zing and a zesty tang. It’s heavily weighted with a strong tea base, but interspersed with lighter citrus notes, themselves dappled with pepper, that lift it into another realm. While the distinctive cologne is enough to set it apart from the pack, the show has only just begun. The next part is simply miraculous.

As mentioned, upon first opening, the bud and bloom are the size of a regular peony. Yet were you to lift it, you would feel the weight and density of a tightly coiled compression of flower power, that, once the sun comes out, and the cycles of a couple of days pass, grows and grows and grows. It doesn’t just open, it actually increases in volume, spilling out of whatever vase you may have inadequately supplied (one per vase is more than enough) and bursting up and out like a super slow-motion explosion. These are monster blossoms, becoming a bouquet unto themselves.

To highlight the show, the colors and shading get in on the action, the petals starting off a soft peach subdued by buttery yellow before gradually deepening into a salmon. The throats of the petal then begin to burn from the base, with hearts of ruby red tinged with fuchsia, like a more delicate version of a peach without the pit. As the bloom ages, the edges of each petal become just barely bordered by the thinnest line of blood red. It is a mesmerizing effect that reveals continually escalating layers of beauty, giddily assaulting all the senses in a display that both burns brightly and glows quietly.

Most tree peonies are grafted onto the more rigorous roots of their herbaceous cousins. While the herbaceous form should only be planted one or two inches beneath the soil line, tree peonies should go much deeper, as the hope is for the tree portion to develop its own roots along the way. Also, they should be allowed to grow into shrub form, so no heavy pruning back until you see what survived the winter. (For that reason those in the upper zones of their hardiness may wish to consider a bit of burlap protection where the winters get harsh.)

Peonies are one of my top three flowers (poppies and iris rounding out the rest) and this past week they have been in their prime. A spell of 90 degree days took the wind out of the early bloomers, which lasted far less than usual in the excessive heat (I saved a few by bringing them into the shaded coolness of our living room) but the cooler days of late seem to be keeping the mid-to-late bloomers intact for their traditional duration.

The fragrance reminds me of childhood, when the neighbors would grant us the luxury of a big bouquet of the peonies, which they grew in a long border along their fence. The perfume filled the first floor of our house – I smelled them before I saw them, having bounded downstairs before being instantly stopped by the brilliance of their perfume. It was the first time the scent of anything stopped me in my tracks. Such is the power of the peony.

Behold the Korean lilac. While smaller in stature and flower than its New England counterpart, this one blooms just after they finish up, and lingers a little bit longer (if temperatures aren’t in the 90’s). For that reason, among others, I find them invaluable. Their smaller leaves are more refined, but do not be fooled by their delicate appearance – they are hardier and less susceptible to mildew than the natives. The blooms are decidedly on the pink side, and the fragrance is just as strong as the traditional lilac, but with a slightly sweeter lilt.

These can be trained into small tree form (I once saw an exquisite specimen done in this manner beside a church. Drawn first to the fragrance, I looked around for a while before realizing its somewhat unassuming smaller flower sprays were the source of such perfume.)

Mine remain as bushes, imbuing the backyard with their potent olfactory effect. Plant them in a bright sunny spot where they can be appreciated, near the doorway or by the pool, to maximize enjoyment.
