Utricularia gibba ( Bladderwort )

This is a floating aquatic annual or perennial with mat-forming stolons. Produces slender stems, feathery, bladder-bearing leaves. Bears pouched, red-veined, yellow flowers above the water. In general, bladderworts may be either free-floating, terrestrial, or epiphytic annuals or perennials. These insectivores live in waters that attract mosquitos. For the most part rootless, these free-floaters have specially developed leaves that have bladders that catch, trap and absorb insects. Flowers are borne atop leafless stems and held above the water. Requires acid water and full sun. Water temperature needs to be 54 to 59 degrees Farenheit for hardy species and at least 66 degrees for tender species. Divide large floating mats in summer.

Plant Care

Fertilizing

Light

Conditions : Sun

Sun is defined as the continuous, direct, exposure to 6 hours (or more) of sunlight per day.

Conditions : Light Conditions

Unless a site is completely exposed, light conditions will change during the day and even during the year. The northern and eastern sides of a house receive the least amount of light, with the northern exposure being the shadiest. The western and southern sides of a house receive the most light and are considered the hottest exposures due to intense afternoon sun.

You will notice that sun and shade patterns change during the day. The western side of a house may even be shady due to shadows cast by large trees or a structure from an adjacent property. If you have just bought a new home or just beginning to garden in your older home, take time to map sun and shade throughout the day. You will get a more accurate feel for your site's true light conditions.

Conditions : Full to Partial Sun

Full sunlight is needed for many plants to assume their full potential. Many of these plants will do fine with a little less sunlight, although they may not flower as heavily or their foliage as vibrant. Areas on the southern and western sides of buildings usually are the sunniest. The only exception is when houses or buildings are so close together, shadows are cast from neighboring properties. Full sun usually means 6 or more hours of direct unobstructed sunlight on a sunny day. Partial sun receives less than 6 hours of sun, but more than 3 hours. Plants able to take full sun in some climates may only be able to tolerate part sun in other climates. Know the culture of the plant before you buy and plant it!

Conditions : Light and Plant Selection

For best plant performance, it is desirable to match the correct plant with the available light conditions. Right plant, right place! Plants which do not receive sufficient light may become pale in color, have fewer leaves and a "leggy" stretched-out appearance. Also expect plants to grow slower and have fewer blooms when light is less than desirable. It is possible to provide supplemental lighting for indoor plants with lamps. Plants can also receive too much light. If a shade loving plant is exposed to direct sun, it may wilt and/or cause leaves to be sunburned or otherwise damaged.

Conditions : Full Sun

Full Sun is defined as exposure to more than 6 hours of continuous, direct sun per day.

Watering

Conditions : Wet

Wet is defined as year-round standing water, such as a concave area of the ground or pond.

Planting

Problems

Miscellaneous

Glossary : Low Maintenance

Low maintenance does not mean no maintenance. It does mean that once a plant is established, very little needs to be done in the way of water, fertilizing, pruning, or treatment in order for the plant to remain healthy and attractive. A well-designed garden, which takes your lifestyle into consideration, can greatly reduce maintenance.

Glossary : Annual

An annual is any plant that completes its life cycle in one growing season.

Glossary : Aquatic

An aquatic is any plant that is grown in water, whether as a floater or rooted in wet soil.

Glossary : Carnivorous Plants

Carnivorous plants are plants which obtain nutrients by trapping and digesting insects or other creatures.

Glossary : Perennial

Perennial: traditionally a non-woody plant that lives for two or more growing seasons.

Glossary : Plant Characteristics

Plant characteristics define the plant, enabling a search that finds specific types of plants such as bulbs, trees, shrubs, grass, perennials, etc.

Glossary : Flower Characteristics

Flower characteristics can vary greatly and may help you decide on a ""look or feel"" for your garden. If you're looking for fragrance or large, showy flowers, click these boxes and possibilities that fit your cultural conditions will be shown. If you have no preference, leave boxes unchecked to return a greater number of possibilities.

Glossary : Foliage Characteristics

By searching foliage characteristics, you will have the opportunity to look for foliage with distinguishable features such as variegated leaves, aromatic foliage, or unusual texture, color or shape. This field will be most helpful to you if you are looking for accent plants. If you have no preference, leave this field blank to return a larger selection of plants.

Glossary : Water Plants

Water plants, often called aquatics, thrive when roots are submerged in water or when soil is boggy or constantly wet. Water level will vary depending on the individual plant. Some aquatics thrive in deep water and actually float on the surface, while others are better suited to swampy margins. Know the care and culture of the plants you are using. Some water plants, such as tropical water lilies, may not be hardy where frost is present and should be stored for the winter, while others, such as iris will do just fine.
