Species roses and old garden roses — both sometimes referred to as antique roses — are the roses that preceded modern varieties. These roses are an incredibly diverse group of plants, with great variety in plant habit (the size and shape), flower form, and fragrance. Some have historical importance; others were useful to hybridizers as breeding stock to create modern rose varieties. Still others, such as the rugosas, are still used in breeding today to create new and better hybrids.
Species and old garden roses have always been popular because of their ruggedness, beauty, and intense fragrance. With these qualities come some drawbacks, however. For example, some species and old garden roses are very vigorous plants that literally can take over a small garden. Others are shy bloomers. In fact, many bloom only once a season. And some are extremely prone to disease.
The size and habit of species and old garden roses dictate how you can use them in the landscape. You can train vigorous types to a fence or arbor like a climbing rose, or leave them to sprawl over a slope as a ground cover. Shrubbier rose types make excellent hedges, or you can mix them in with perennial borders. Even though many bloom only once, in the spring, old roses often make up for it by producing colorful hips that last long into winter. Others have attractive foliage that looks good throughout the growing season. Most antique roses have very interesting flowers. They’re usually flat-topped, rounded, and rather cup-shaped, with many petals. If you like cut flowers, antique roses are tops. Although most don’t have the strong, straight stems of modern hybrid teas, their beautiful flower form makes for a unique bouquet. And oh, the fragrance! It’s not always there, but when it is, it can be overpowering.
Just remember one thing about many species and old garden roses: They usually grow on their own roots, so they often spread like crazy, forming dense thickets. Make sure that you plant these roses where they have plenty of room to grow.
Many species and old garden roses need less care than modern roses do. In fact, many seem to thrive on neglect. However, where summers are dry, regular watering is necessary to keep the plants healthy. And almost anywhere, applying fertilizer regularly keeps the plants growing vigorously. Prune your plants to keep them within bounds and remove dead branches. But, other than that, less pruning is probably better than more. Prune roses that bloom just once in spring after they bloom, if at all. If you prune in winter or late spring, prior to blooming, you remove branches that would otherwise produce flowers. You can prune repeat bloomers in winter to early spring as with other types of roses.
Few nurseries and garden centers carry a wide selection of species and old garden roses. For the best selection, you have to order plants from a catalog that specializes in antique roses.

Gardening Glossary
annuals
Plants that complete their entire life cycle within one growing season. The plant germinates from seed, grows and blooms, and then produces seed and dies.

Gardening Glossary
biennials
A plant that take two growing seasons to complete its life cycle. It germinates and grows leaves and stems in the first year; produces flowers and fruit (seed) in the second, and then dies.

Gardening Glossary
hardiness
The ability of a plant to survive is called its hardiness.

Gardening Glossary
humus
A stable end product of organic-matter decomposition that's believed to increase microbial activity in soil, improve soil structure, and enhance the root development of plants.

Gardening Glossary
Bacillus thuringiensis Bt
An effective bacteria that attacks only the larvae of caterpillar family insects. It is safe to other insects, animals, and humans.

Gardening Glossary
macronutrients
Mineral nutrients that plants need in the largest quantities: nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur.

Gardening Glossary
mulch
Organic or inorganic material placed over the surface of soil, usually directly over the root zone of growing plants. Used to conserve moisture, kill weed seedlings, modify soil temperature, provide attractive covering to garden beds.

Gardening Glossary
organic matter
Once-living stuff like compost, sawdust, animal manure, ground bark, grass clippings, and leaf mold (composted tree leaves). Used to enrich soil and improve soil texture.

Gardening Glossary
perennials
Any plant with a life cycle of three or more years. Herbaceous (non-woody) perennials include flowering plants and herbs, mainly. Woody perennials include trees and shrubs. Longevity depends on the plant and growing conditions.

Gardening Glossary
pH
The measure of soil's acidity. Soil with low pH means it's too acidic; soil with high pH means it's alkaline. Most plants grow best in soil with a pH value between 6.5 and 7.2. Neutral soils measure 7.

Gardening Glossary
photosynthesis
The process through which plants take nutrients from the air and from the water in the soil to produce sugars that fuels the plant's growth.

Gardening Glossary
primary nutrients
Nitrogen, phosphorous, and potassium are the three nutrients plants need in the largest quantities.

Gardening Glossary
root crops
Plants with edible underground roots such as onions, carrots, beets, potatoes, turnips. Most root crops are cold-weather crops.

Gardening Glossary
thinning
The act of cutting the least robust seedlings in your garden to give the healthier plants more room to grow.

Gardening Glossary
vining crops
Crops that grow on vines, such as cucumbers, melons, pumpkins, and winter squash. They usually require support (staking, trellising, etc.) to keep them off the ground.
