Plant Gardens 101

While selecting flowers seeds for gardens or for landscaping purposes, an increasing number of people are selecting wildflower varieties. Botanists and flower enthusiasts advocate against the usage of the term “wildflower”. Expressions such as “native”, “exotic” or “introduced species” are recommended to refer to flowers not logically occurring in an area. Other frequently used terms are invasive species and imported or naturalized varieties. These terms are used to refer to plants launched in an area much earlier and now considered as native to the location.

A wildflower is a type of flower that grows in uncultivated places, indicating that it was not seeded or planted by humans with a purpose. Taking this into consideration, it may seem strange that wildflower seeds of a few mixed species are being sold in seed packets. (more…)

The Amazon jungles, mangroves, virgin forests, tropical forests and even plants in a kitchen garden have all originated from seeds. Many plants have survived over the ages through wind dispersals and alternative forms of reproduction. However, the predominance of gymnosperm and angiosperm plants in all landscapes confirms the importance of a seed.

A ripened ovule of a gymnosperm or angiosperm is called a seed. An angiosperm or a flowering plant has a seed enclosed in the ovary that later forms a fruit. Gymnosperm, conifer and related plants seeds lie open to the elements. A seed contains an embryo, which facilitates growth of a new plant under favorable circumstances. It also has a supply of accumulated food and is wrapped in a seed coat. This stored food is initially a tissue called endosperm derived from the parent plant. Over time, the endosperm becomes rich in oil starch and protein. In some species, the embryo is embedded in the endosperm, which will be used later by the sapling, upon germination. In some other species, the embryo absorbs it as it grows within the developing seed. (more…)

Flowers have been grown and nurtured over years for personal and business purposes. A flower provides visual bliss in addition to a soothing aroma and an array of delightful colors. One can give cut flowers as gifts to celebrate events, express feelings or just grow them in a backyard.

It may sound strange when a botanist refers to singular divisions of a flower while referring to male and female reproductive organs. However, this is true. Flowers are used as a reproductive organ only in certain angiosperms plants. A pistil is located in the center of a flower and it contains female organs. It has a rounded lower base, which is the ovary. These contain reproductive cells called ovule. (more…)
