Explanation:

Perennials

Perennials are plants that can live for three or more growing seasons (oftentimes, especially in St. Louis, bulbs must be planted in autumn to produce spring-blooming plants). Garden Heights Nursery carries a wide variety of container perennials grown for sun and shade. Daylilies, peonies and hellebores are common perennial plants. Garden Heights Nursery is proud to carry a variety of native perennial plants that are beneficial to our local eco-system, providing habitat to butterflies, birds and bees!

Annual Plants:

While annuals live for only one season, they tend to have a long bloom season. They are usually bright and showy, used by gardeners to add burst of bright color to their flower beds and container gardens. Popular annuals include petunia, vinca and lantana. Garden Heights Nursery carries a vast variety of both full sun and shade annual plants in containers. Check out our selection this spring!

Parameter Angiosperms Gymnosperms

Definition These are seed-producing flowering plants whose seeds are enclosed within an ovary. These are seed-producing non-flowering plants whose seeds are unenclosed.

Seeds Their seeds are enclosed inside an ovary, usually in a fruit. Their seeds are bare and not enclosed, which are found on scales, leaves, or as cones.

Life Cycle The lifecycle of these plants is seasonal because these die during autumn/fall. These plants are evergreen in nature.

Presence These are present in flowers and can be unisexual or bisexual. These are present as cones and are unisexual.

Reproduction Reproduction is depending on the animals for spread. Here, Reproduction is depending on wind for spread.

Fibrous root:

A fibrous root is a root that consists of groups of roots of similar size and length. They do not penetrate as deeply into the soil as does a taproot.

The fibrous root is a feature of plants that are monocotyledons. Unlike the tap root, the primary root produced during development does not remain, and instead roots, known as adventitious roots, are produced from the stem of the plant.

Taproot:

A taproot is when there is one main root that grows straight down deep into the soil. It only has very few lateral roots that develop and grow off this main root.

The taproot is a feature of plants that are known as dicotyledons and it is also found in the plants known as gymnosperms

Parallel Venation

Veins are parallelly arranged with one another and mostly occurs in monocots

Presence of midveins classifies parallel venation into –

Pinnate parallel venation/unicostate parallel venation – veins emerge from evident midvein found in the centre of the leaf lamina from the base to the apex where veins develop perpendicular to the midvein towards the margin and are parallel to each other. Example- as seen in banana leaves

Palmate parallel venation/multicostate parallel venation – several prominent veins, running parallel to each other. It, in turn, can be of two types – convergent parallel venation and divergent parallel venation. Example – Borassus, Grass

Reticulate venation

Veins are arranged in the form of a network and mostly occurs in dicots

It can be classified into the following two types:

Pinnate reticulate venation/unicostate reticulate venation – one midvein is present and all other veins form a mesh-like structure

Example – as seen in Mangifera leaves

Palmate reticulate venation/multicostate reticulate venation – Midribs are found, others veins form a network. The venation here is of two types – convergent and divergent reticulate venation
