ACIDIC SOIL

Soil with a pH of less than 7.0 is called acidic soil.  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.

ALBESCENT COLOR CHANGE (Hosta)

The word alba means white, and hostas that whiten from yellow or chartreuse to white are called albescent.

ALKALINE SOIL

Soil with a pH of more than 7.0 -- Plants growing in more alkaline (or basic) 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 the mineral lime. It can be purchased in powder form at most garden centers.  Most perennials grow best in soil with a pH of about 6 or 7.

ANNUAL
A plant that completes its growth cycle in one season.
ASEXUAL REPRODUCTION

The typical method of plant propagation that involves vegetative division of a clump, rooting of proliferations, or cutting of mature crowns. Asexual propagation produces clones, i.e., plants that are identical in all attributes to the mother plant and to one another. Daylilies cannot be propagated true-to-form from seed.
