A gardener raises plants for their beauty, a botanist studies them for their biology, but in anyone who tends a garden there’s the soul of a scientist. Plants grown for delight also invite inspection of their form, their life cycle, where they like to grow and where they do not. This perception is central to one’s growth as a gardener.

Inspired by the curious flora that grows in the dry, stony and weather-beaten universe of mountains, gardeners a century ago became gripped by a mania to build rock gardens. The craze passed.

Joseph Tychonievich is a young horticulturist and rock garden devotee in Michigan who says we are due for another moment of alpine mania. His contemporary pitch: Once built, rock gardens are inherently low maintenance, and diminutive versions can be squeezed into small urban gardens. This “classic design is coming back into style,” he writes in his new book, “Rock Gardening.” I hope he is right, though “dry gardening” may be a better contemporary term for this horticultural niche.

In its most literal aping, a rock garden has to be an enormous assemblage of big stones and gravel to be a convincing replica of an upland rockscape. (The best private one I’ve seen is at the late Frank Cabot’s Stonecrop in Cold Spring , N.Y.) Or it can be abstracted, either in a modest but elegant faux stone trough or as a growing bed dominated by gravel.

In many gardens where they were a major feature, they failed, aesthetically and emotionally, because they were not bold enough. They erupted as a huge pile from a clay lawn, or next to the driveway and the picket fence. Thus, something contrived to feel supremely wild and natural instead looked absurdly imposed on the land. They were overdone and underbaked at the same time.

This awkwardness could be mitigated by the curiosity of alpine plants — they tend to be dainty and decorative in an esoteric way — but what happens when the keen originator loses interest or moves away? You are left with a pile of stone and gravel that grows dark with decaying leaf litter and weedy with invaders. Along much of the Eastern Seaboard, the other factor working against rock gardening is a hot, humid region that is decidedly not the optimum environment for alpine beauties that evolved to want hot, bright days, cool nights, a constant breeze, superb drainage and, in winter, a protective blanket of snow.

However, you would be amazed at how many of our common garden plants that put up with heavy clay soil flourish in a location that is essentially stony, free-draining and with soil on the poor side. The list includes irises, poppies, coneflowers, gaura, milkweed, torch lilies, yuccas, heaths and heathers, dianthus, thyme, amsonias, ice plant, and penstemons, not to mention grasses. If you want to explore true rock garden plants — some need partial shade — you may want to join the North American Rock Garden Society, whose members exchange seeds of more esoteric species. One way to play with these wee gems is to build hypertufa planters, a great winter project for the stymied gardener.

Unless you have deep pockets and the right setting, I’d say the old-fashioned rock garden is better reincarnated as the gravel garden. This is far more modest in its presence, though you would be surprised at how much material an area of land can swallow up. A gravel garden is flat or gently sloped, the soil is heavily amended with sand and gravel, and the whole bed is mulched with aggregate, typically pea gravel. As long as the growing area is well defined and doesn’t bleed into the lawn, for example, gravel gardens read as sophisticated plant beds rather than as oddities.

If you want to see how a gravel garden can open up a whole new world of horticulture, visit Chanticleer Garden in Wayne, Pa. (open from April to October). Its Gravel Garden is richly planted with sun-loving perennials, herbs, bulbs, grasses and self-sowing annuals. It peaks in the summer and fall when other gardens are flagging.

I have bracketed my community garden plot with two modest and fun gravel beds, each 20 feet long but just two feet wide. The plants must be deerproof here, so the beds are full of herbs that will go uneaten and are liberally seeded with Shirley and California poppies.

The best thing is that bulbs love these environments and return reliably year after year when they have such an open and free-draining soil. Because deer and squirrels leave daffodils alone, I’ve gone to town with narcissi in these strips. (Allium, of which there are many species and varieties, also love gravel gardens and stand a much better chance of perennializing there than in an ordinary garden bed.)

This year, I’ve added Hawera, a classic, mid-season dwarf daffodil with cheerful canary-yellow blooms, and Prototype, a daffodil I haven’t grown before that was developed by Brian Duncan, a breeder known for his exquisite introductions with pink- and rose-colored cups. It has greenish-yellow petals folded back a little and a soft-pink cup. The third is the golden-yellow Rapture, another cyclamineus type.

Lastly, I’ve planted Baby Moon, a sweet and buttery-yellow dwarf jonquil that will see out the daffodil season with its ebullience and perfume. And with a price of 17 cents a bulb, I could afford to stick in 100 of them.

Plunging the trowel into the gravelly soil is quite easy, but by the time I had finished, the clean pebble mulch effect had been lost as soil was churned to the top and the gravel worked its way into the ground. A fresh mulch of gravel will restore the look while I wait with anticipation through the winter for the emergence of these pretties. With gardening, it’s fine to have rocks in your head.
