- (of soil) With a ph value of less than 7. Plants growing in more acidic soils are less able to absorb nitrogen, phosphorus, and potassium. If you have a soil that is high in acidity an easy way to remedy this is to add organic material or lime. This will bring the ph level up and create a more hospitable environment for your plants.Most perennials grow best in soil with a ph of 6-7.
- (of soil)With a ph value of more than 7.Plants grown in more alkaline soil are less able to absorb phosphorus, iron, and manganese.If you have a soil that is highly alkaline an easy way to make the soil more neutral is by adding organic material.Most perennials grow best in soil with a ph around 6-7. Amendments Soil amendments are materials which are worked into the soil to enhance the soil properties. Examples include organic matter such as compost.
- A plant that completes it growth cycle in one season.
- The darker colored area of a daylily flower that is positioned just above the watermark on the petals only.
- Bare Root
- Of plants sold with their roots devoid of soil. Also referred to as Eco-Roots™ an environmental plant. Examples include: daylilies, hostas.Anything shipped in this form needs to be planted immediately.
- Basal Leaf
- A basal leaf grows from the lowest part of the stem.Basal, refers to the base of the structure.Certain plants, like Scabiosa, retain their basal foliage both in winter and spring.
- A plant that flowers and dies in the second growing season after germination.
- Botanical Name
- Standard, universal names that allow you to purchase the plant you want.It is best to shop by botanical name since a common name can apply to more than one plant.
- Of trees or shrubs with broad, flat leaves rather than needlelike foliage.
- Unexpanded leaf, stem, or flower that will develop at a later time.
- A modified stem acting as a storage organ.The stems and leaves are not usually recognized as such.
- Clay Soil
- Soil composed of many very fine particles, sticky when wet but hard when dry; water and air have a hard time moving through the clay soil.This soil requires amendments in order to grow an array of garden plants successfully.
- Common Name
- Common Names are what most of us grew up on and can vary from region to region. Example: Hemerocallis is the botanical name, where daylilies is the common name. Compost Material that is rich in organic matter, formed by decomposed plant remains. Examples include: manure, garden waste, kitchen scraps, leaves, grass clippings, straw. Although compost is not high in nutrients, it is a valuable soil amendment because it can help improve soil structure.
- Gardening Plants grown in containers with soil.
- Usually evergreen trees and shrubs, that are distinguished from flowering plants.
- The plant crown is where the plant meets the root. Most plants are planted so that the crown is at soil level.Some plant crowns like to be planted higher such as Platycodon, while other plant crowns such as Clematis benefits by being planted a few inches below the soil.
- A contraction of "cultivated variety" -a group of cultivated plants that has been selected either from the wild or from gardens and grown in cultivation, and whose characteristics are by some means of controlled propagation (such as cuttings, root cuttings).New cultivar selections are rapidly gaining in popularity because of improvements in such areas as disease resistance, improved habit, color, etc.Cultivars are always designated in single quotes such as Leucanthemum superbum 'Becky'.
- Stir the soil surface to eliminate weeds, aerate the soil, and promote water absorption.
- The removal of spent flowers or flower heads. Deadheading is accomplished by pruning spent flowers with your hand, small hand held pruner, or knife.Most perennials and annuals will continue to bloom throughout the season if deadheaded.An excellent book, by Tracy Disabato-Aust called 'The Well-Tended Perennial Garden' explains in detail the processing of deadheading by plant. Note:This is a maintenance step that takes time, but your efforts will be rewarded with continuous bloom!
- Plants that shed their leaves at the end of the growing season.An example of this is Hydrangea. Plants that do not shed their leaves are referred to as evergreen.
- A plant with two basic sets of chromosones.
- A method of increasing plants by dividing them into pieces, each with a root system and one or more shoots.As a general rule, many plants can be divided in the fall or early spring.Hostas for example can be divided throughout its growing cycle, but you can damage their beautiful leaves if divided during the summer.
- The state of temporary cessation of growth, especially during the winter.As a general rule, most hardy plants require a dormancy period (rest period).
- The passage of excess water through soil.
- Early Bloom
- (Daylilies)Having a bloom time early in the season which is typically late June to early July.
- A select group of bare root plants. Not all bare root plants lend themselves well to the storing, shipping, and handling process before they arrive to the gardener.Eco-Roots™ are carefully scrutinized for their performance and handling along with the added benefit of cost-saving and environmental friendly.
- Plants that retain a substantial portion of their foliage for more than one growing season. Semi-evergreen retain only a small proportion of their leaves for more than one season.

- A category in plant classification, a grouping together of related genera.
- Any of a large number of organize and synthetic materials that are spread on or worked into the soil to increase capacity to support plant growth.
- Fibrous root system is usally formed by by thin, moderately branching roots growing from the stem.
- The part of the flower containing the reproductive organs usually surrounded by sepals and petals. Single flower has one row of usually four to six petals. Semidouble, with two or three times the normal number of petals in several rows. Fully double, flowers usually rounded in shape, with densely packed petals and with stamens obscured or absent.
- Flower gardening
- The practice of gardening with plants.
- Flower head
- A mass of small flowers or florets that together appear to form a single flower. Full Shade Full shade is defined as fewer than 4 hours of direct sunlight per day. This term is often used interchangeable with part shade.
