Tropical sage: a Florida native wildflower

Tropical sage (Salvia coccinea) is a beautiful, easy-to-grow Florida native wildflower in the mint family, Lamiaceae. It has a long blooming cycle and its flowers are usually scarlet red, but sometimes are pink, even in natural areas. In addition to attracting hummingbirds, butterflies and native bees, tropical sage is the larval host for several sphynx moths. 

It's considered to be an annual, but I've had many that have lasted for two seasons and it's a prolific reseeder. So this plant is a wonderful addition to your pollinator gardens and wildflower meadows.

Roselle: Florida's cranberry

Roselle (Hibiscus sabdariffa)

The calyces subtend and support the petals. The flower lasts for only one day and when the petals fall off, the sepals begin to swell to surround the developing fruit. 

The five overlapping petals of the roselle flower are pale yellow tinged with burgundy on the edges and becoming deep burgundy in the center of the flower where the pistil emerges.

The mallow family: Malvaceae

Removing invasive plants in Florida costs $54 million per year

a Category I invasive in all of Florida.

Yet, many of these plants are still for sale

How did we get into this situation?

A few hundred years ago, once world travel was readily available, many plants and animals were transported from their native habitats where natural checks and balances evolved over millennia so that predator & food sources were in balance. (I will be talking about plants in this post, but invasive animal species are also a huge problem in Florida.) 

People moved thousands of plant species for a number of reasons:
- to bring food crops with them as they settled into new places.
- they collected beautiful plants from around the world to plant in gardens as a novelty or for prestige.
- Some plants were imported for their utility such as stopping erosion (such as kudzu (Pueraria montana)) or building fast-growing hedges (such as, Brazilian pepper (Schinus terebinthifolia)).
- Many non-native plants have been favored in the landscaping industry because most local insects and other critters do not feed on them, so they are easier to grow and sell, because they "look good."
and...
- Sometimes the plants were introduced to new regions by accident as hitchhikers with other plants or with other products that were being transported.

What is "invasive" and how is that status determined?

Wild sweet basil

Wild sweet basil has lavender flowers
unlike sweet basil and lime basil which
have white flowers.

Florida's native basil

Wild sweet basil (Ocimum campechianum) is warm-weather herb related to sweet basil (O. basilicum) and lime basil (O. americanum). (Lime basil can tolerate Florida's hot wet summers, which I wrote about in two previous posts.) Unlike those traditional basils so popular in the Mediterranean cooking, which are native to India, Africa and Southeast Asia, this wild basil is native to the southernmost Florida counties, the Caribbean islands, Mexico, Central America, and most of South America.

Since we live in northeast Florida, this plant is not a true native here, but South Florida is MUCH closer to home than Africa or India, so this species of basil would be a regional native that should be better adapted to our climate with our hot, wet summers. Sweet basil often suffers from fungal diseases during our wet summers. 

Peat moss is never sustainable

There are many reasons why peat moss is never recommended for gardening.

Leeks: Growing and using this garlic relative

Freshly harvested leeks have had most of
their leaves chopped off above their fat stems.

Leeks (Allium ampeloprasum) are native to the Mediterranean region and were developed as a crop in Europe and their mild taste makes them a favorite for soups. They form a thick stem at the base that continues fairly high into the plant. The flat, solid leaves are folded and grow on opposite sides of the stem, but no true bulb is formed. Because the leaves are flat, leeks are on the garlic side of this genus and indeed elephant garlic is a cultivar of this species (A. ampeloprasum var. ampeloprasum). The onion side of this genus has hollow leaves like chives.

Bountiful harvests of early summer

Cooking to the harvests

Because of the pandemic, we haven't been traveling since March 2020, which has resulted in many more crops and harvests that would not have been possible otherwise. Normally, we would have been traveling at various times during this period--mostly to be a guest presenter on cruise ships--so we would not have been able to accomplish this.

Our freedom lawn

We let our lawn go wild!

When we first moved into our house, the lawn-care guys who had worked for the former owner stopped by to offer to continue their services. When I refused, they said that without their poisons (fungicides, insecticides, and herbicides) and their specially-formulated fertilizer and weed & feed applications that our lawn would die. Well, as it turns out, a few months later some brown spots did develop, but they were soon taken over by other plants, which those lawn guys would probably have condemned as "weeds."

Science-based companion planting

by Jessica Walliser at Amazon.

Much has been written about which plants work well together, and often the various human emotions, such as love and hate, accompany these descriptions. Extension agents, university professors, and other scientists had debunked most of the anecdotal benefits of traditional companion planting. 

But now there is new science on using various plants to:
- act as trap crops to lure pests away from crops,
- attract predatory insects that will reduce pest problems on crops,
- add diversity, which may confuse pest organisms.
- reduce weeds,
- increase pollinator populations,
- add nutrients, and more.

Jessica Walliser's new book, "Plant  Partners: Science-Based Companion Strategies for the Vegetable Garden" (published by Storey Publishing) is the winner of a 2021 The American Horticultural Society Book Award. Jessica is a rare two-time winner of this prestigious award and her book compiles this latest research on using plants to accomplish several benefits in vegetable gardens. 

The lettuces

Lettuces: fast, easy-to-grow, cool-weather crops

I planted four types of lettuce in this bed: oakleaf,
black-seeded Simpson, drunken woman, & romaine.

Here in North Florida, we grow our cool-weather crops right through the winter. At the end of September, I planted four types of lettuces in a bed next to the house and also planted a curly parsley row there as well. The lettuces were oakleaf, black-seeded Simpson, drunken woman (which was new for us), and romaine. They all did very well, but the romaine gave us the longest and best harvest. I was remiss in not taking any good photos of this bed while it was in its peak. 

With leaf lettuces, you can harvest the outer leaves as needed or you can cut the plant off just above ground level with the hope that the plant would produce new leaves for a second or maybe a third harvest while the weather is still cool, This works best in Florida with varieties of lettuce that are more tolerant of warm weather or ones that are described as "slow-to-bolt."
