Thinking of bulbs for the garden? Summer is not necessarily the time of year that gardeners think about beautiful blooms from bulbs and bulb-like plants, but there are many that bloom in the summer garden.
In general, many types of plants with an underground storage organ are classified as a bulb. These include plants with tubers, rhizomes, or corms. True bulbs including Lycoris and Crinum lily are compressed stems with a growing point surrounded by thick, fleshy scales. Corms such as Crocosmia are solid masses of stem tissue with a terminal bud and side nodes. The rhizome is an underground stem that grows laterally, with representatives of this type being blackberry lily and ginger.
It is likely that your garden is full of bulb-like plants and you were just not aware of their underground beginnings. If you want to consider a few more for the summer garden, here are some good choices.
Blackberry lily is a member of the Iris family that offers good summer bloom in our northern Florida gardens. Plants form sprays of foliage about 2 feet in height with stalks of orange flowers with red spots. Plant in full sun or partial shade and supply with well drained, amended soil.

Another bright summertime bloomer is Croscomia. Commonly overlooked early in the year as foliage regrows from the cold, the bright orange flowers that emerge in summer make it a feature in garden beds. Plants grow well in both full sun and partial shade but clumps can expand easily beyond the desirable planting area. Thin out every few seasons to keep the clump manageable.
A tuberous perennial that will have stunning flowers closer to eye level is the Gloriosa or flame lily. Plant stems will wind around a trellis or garden feature, hold on with tendrils, and support large upward-curved petals. Flower colors are red, yellow, orange, or mixes of several colors. Flame lily prefers sunny locations and lots of moisture in the growing season. Winter soils should be drier to prevent tubers from rotting.

All of these options can enhance your garden and extend your bulb growing season beyond the spring. Happy Gardening!

Gaillardia is a favorite one of many wildflowers throughout the United States. It is a member of the Aster family, and is most commonly known as Indian Blanket or Blanket Flower. Individual plants can reach up to 2 feet high. They are heat and drought tolerant and, in Northwest Florida, flower from summer through fall.
The entrance to the Gadsden County Extension Office is flanked on either side by stands of Indian Blankets. Blooms are an array of red, orange, and yellow. While it may be rare to find a flower with the center cone and petals completely yellow or orange, they are evident in our garden. What most people find peculiar is appearance of tubular, trumpet-like, florets on the flower ray.

The striking display of flower color Indian Blanket offers is not its only feature. It is also a source of nectar for many different butterfly species. Stephen Brown, a horticulture agent in Lee County Florida, has an excellent publication on Gaillardia pulchella that lists this plant species’ interesting attributes.

Bring your own blend of fireworks to the garden this July by adding the Red Rocket Russelia, Russelia sarmentosa to a full sun area.

A favorite perennial to those who grow it, the Red Rocket has many positive qualities that make it a must have for everyone. Plants form a large group of arching stems that grow 5-6 feet in height. Clusters of tubular red flower occur at each node, covering the entire stem in color. Flowering occurs soon after regrowth from winter cold and continues until the first frost. Once established plants perform well with occasional irrigation or a routine rain shower. The added bonus of this colorful perennial is that hummingbirds visit flowers often to feed on nectar.

Butterflies are not only beautiful to look at in the landscape; they serve as important pollinators of fruiting plants. Attracting them to the garden and incorporating some features to get them to stay and reproduce involves advanced planning. Some steps to achieve butterfly garden optimization are outlined below.
- Choose a location that provides some protection from wind. Trees and shrubs that provide wind protection also serve as a safe harbor from rain and predators.
- The garden should offer both sunny and partially sunny environments.
- Ensure that any new plantings have access to a convenient irrigation source. A plentiful water source allows butterflies to be successfully established and maintained in good health.
Now plants need to be chosen. Adults feed on the nectar of many flowering trees, shrubs, perennials, and annuals. Fortunately, there are usually many choices that will meet diverse site requirements and varied taste preferences. In order to retain garden butterflies, certain plants need to be available to serve as host plants for their young. Here are a few hits to assist with this selection process.
- Determine which species of butterfly is common in a given geographical area. Most species have very few plants on which the caterpillars can feed, so host plants need to be chosen wisely.
- Determine whether any of the existing plants are host plants and if they are appropriate for a butterfly garden. For example, cassia is a host plant for the Cloudless Sulphur and citrus is a host plant for the Giant Swallowtail.
- In choosing nectar plants, select those that are native or Florida-Friendly as they are lower maintenance, and less troublesome in the long run.
- Choose plants that have flowers in a variety of color, size, and shape. Different butterflies like to feed at different elevations, so choose trees, shrubs, perennials, and annuals of varying heights.
- In order to have nectar available throughout the time when the butterflies occur, include plants that bloom at different times of the year. And include some plants that bloom all the time, like pentas or moss verbena.
Larger plants should be placed in the background with smaller plants layered in the foreground. When planting smaller annuals and perennials, place them in masses to better attract the butterflies. Consider placing host plants in an area that is in close proximity to the nectar plants, but in an area of your garden that is not a focal point. Host plants can get quite ragged looking from hungry caterpillars!
Good maintenance practices will enhance garden health. Regular fertilization, and as needed irrigation, will help keep garden plants in bloom and healthy – healthy plants are less susceptible to disease and pests. Avoid pesticides as they may harm butterflies and other beneficial insects. Never use a Bt or systemic pesticide since these target butterfly larvae. Lower risk oils or soaps are useful in treating localized insect infestations however. Lastly, be aware of beneficial insects that will help achieve satisfactory pest control.
Once the plants are placed there are several things to do to complete the butterfly garden.
- Add a spot where water can puddle on the ground for the adult butterflies to drink. They require minerals from the soil that get dissolved in the water.
- Also add a rock or log in a sunny spot where butterflies can rest and sun themselves.
- Consider placing a comfortable place for you to sit and enjoy the beauty of your garden and its inhabitants!
