Glossary of Terms

Companion Plants:
Plants which fit in well with designated plants. Aspects include size, color (flower or foliage), site condition (wet, moist, dry), light conditions (sun, partial shade, shade), growth habit, function (bank, stream side, deer resistant, salt tolerant).
Future Crop:
Expected Future Crop quantities are listed on our website and on our Current Availability. Future Crop “Ready Dates” are highly determined by the weather; please feel free to contact the office with get approximate ready dates for future crops.
New Plants:
Plants that are either new to our production this year, or those which are being reintroduced into production after being unavailable for several years. These plants were not included in the current year’s catalog.
Similar Plants:
Plants which have certain characteristics which serve the same function as the original plant (deer resistant, native, flower or foliage color, . size, exposure, soil conditions, etc.).

The Advanced Search feature has been enhanced to allow users to search for ALL plants that meet their criteria OR only plants that are currently available. This will limit the results to only display options for plants that can immediately be purchased, helping to avoid customer disappointment (plant is not currently available). Please note: This will not include or account for Future Crops. Don’t forget, you may call the office to check on future crop ready dates. The new Inventory Status searchable tool will be just on the bottom of the Advanced Search page, just above the "Begin Search" button on the bottom of the page.

Plant Characteristics Search
Bloom Times:
  • Winter: December – February
  • Spring: March – May
  • Summer: June – August
  • Fall: September – November
Sun: Greater than 6 hours
Partial Shade/Shade Tolerant: Between 3 and 6 hours of direct sun
Full Shade: Less than 3 hours of direct sun
Soil Conditions:
Dry soils- water moves rapidly through the soil; soil is moist for brief periods following precipitation.
Moist soils- hold adequate moisture through the year.
Wet soils- hold visible water for most of the year.
Winter Interest:
Flower- winter flowers or catkins
Foliage- plants whose foliage takes on attractive foliage colors in the winter months
Fruit- colorful fruit present in winter
Seedheads- attractive seedheads in winter
Structure- plants with unusual branch habits or interesting silhouettes
Zone: (USDA Hardiness Zone)
The zones on our website are based on research performed and published by the USDA, resulting in their “USDA Hardiness Zone Map”. We list the zones for the coldest temperature which the specific plant will tolerate in normal Northeastern winter conditions.
Plant Characteristics Search - ATTRIBUTES
Attracts Pollinators:
Identifies plants whose flowers serve as a significant food source for butterflies, moths, native bees, honey bees, flies, beetles, hummingbirds or bats.  The food source can be nectar and/or pollen.
Cut Branches:
Woody Plants which offer which are ornamental when brought indoors because of flowers, fruit or twig color.
Cut Flowers:
Herbaceous plants with flowers with long enough stems to be displayed in containers indoors. Includes dried flowers and grass seedheads.
Deer Resistant:
Plants which have sap or foliage which is very distasteful to deer. This refers to eating, not buck rubbing. Virtually no plant is deer proof, because in starvation conditions deer have been shown to eat almost any plant.
Drought Tolerant:
Plants which usually do not require supplemental irrigation after they are established in the landscape, even during prolonged droughts.
Dry Shade:
Plants which tolerate receiving only a few hours of direct sunlight in soils that usually have little moisture. These conditions are usually found under trees or shrubs where the shorter plants have to compete with the tree or shrub roots for moisture while growing under the drip lines. Another situation where dry shade conditions exist is in close proximity to walls or buildings where the structure makes a “rain shadow”.
Erosion Control:
Plants whose fibrous root systems and branching habit make them able to stabilize soil on a slope or on sites periodically inundated with rain runoff.
Food Source for Wildlife:
Plant which provided dependable food to insects, birds, mammals or reptiles, in the form of nectar, pollen, fruit, seeds or nuts.
Plants which spread by rhizomes, stolons, branches or roots to make an increasingly large patch which deters germination of unwanted seedlings. We classify perennials a groundcover if they are 18” or less having a spreading habit (rhizomes, stolons, rooting branches or roots) which makes an increasing large patch. We have noted in the text some taller perennials for use as a groundcover as a result of their vigorous spreading habit.
Habit: Compact
Identifies species or cultivars within a Genus that are smaller in size than the standard size.
Plants originating in the Eastern United States.
Perennial Plant of the Year:
To showcase a perennial that is a standout among its competitors. Winners are suitable for a wide range of growing climates, require low maintenance, have multiple-season interest, and are relatively pest/disease-free.
PHS Gold Medal Plant:
The Pennsylvania Horticultural Society recognizes trees, shrubs, woody vines and now perennials too of outstanding merit. Plants are evaluated and chosen for their superb eye-appeal, performance, and hardiness in the growing region of Zones 5-7 as well as for their multi-season interests (foliage, flower, form or bark).
PRN Preferred Selection:
We've been asked to highlight some of our personal garden favorites.  We have found that these plants have proved excellent in both production and landscape settings.  Some of them "lead the pack" in flower beauty, foliage color or length of bloom times.  Some show a superior growth habit and disease resistance.  Others are consistently excellent but simply underused.  Lastly, some of them offer multiple seasons of appeal and should be a staple of many landscapes.
Salt Tolerant:
Plants that survive significant exposure to ocean salt spray.   Sources: Univ. Wisconsin Extension, Greenbelt Native Plant Center & NYC Parks & Recreations.
Evergreen- covers both conifers and broadleaved trees.
Fastigiate- upright narrow habit with erect, dense branching.  Useful for tight spaces.
Ornamental- 30’ or less, with noteworthy blooms, bark and/or foliage.
Shade- greater than 30’.
Street- Single stem/Tree form, branching (5’ or higher should be the eventual starting point), the root habit (for sidewalk preservation), the soil requirements (not a fussy forest tree), and litter production (heavy fruit bearing trees are messy).
Wet Site Tolerant:
Plants which thrive in sites with constant moisture or periodic standing water.
All plants are listed by Botanical name
