Petunias are moderately easy to grow from seed, and extremely easy to grow from commercially grown seedlings. The low growing types are ideal for the front of a flower border, in planters near doorways and windows, or in containers in the back of the house. Prunus serrulata is an evergreen shrub or small tree that can grow up to 10 feet tall.
It can be used as an ornamental or as a ground cover. This plant is very drought tolerant and will tolerate a wide range of soil types and temperatures. Prunus is a very hardy plant that will grow well in a variety of soils, including sandy loam, peat moss, sand, clay, silt, organic matter, composted manure, manure-based fertilizers, potting soil and organic mulch.

Do petunias multiply?
The most common types of seeds are those that are produced by hybridization. Hybridization is the process by which two plants of the same species are crossed to produce a new plant that is genetically identical to the parent. The resulting plant is called a “cross-pollinated” plant, and is often referred to as an “inbred” or “hybridized” variety.
In the case of hybridized seeds, the two parent plants are grown together in a controlled environment, such as a greenhouse, to ensure that the resulting plants have the desired characteristics of both parents. For example, if one parent is a tomato plant and the other is an apple tree, then the result will be a hybrid tomato and an inbred apple.
How many petunias are in a 12 inch basket?
