Iconic Tree of the Southern States




My second-most admired tree in the southern States of Florida, Alabama, Mississippi and Lousiana are the "Bald Cypress". I discovered this tree during a walk in a residential area in Florida, and the owner gave me its name.  When googling it, I realized that these are the legendary “swamp trees” in countless photographs I have seen before.

It’s hard to mistake the Bald Cypress (Taxodium distichum) for any other tree. These tall conifers with flared trunk bases are representative for the Florida Everglades and Louisiana - where it is the State Tree.

They prefer to grow in swamps and bayous of the southeastern United States from Maryland to Texas.  You will notice them later in the year for the beautiful russet-red fall color of its lacy needles.



These trees can also thrive in drier, upland soils in plant hardiness zones 4 through 9 - if watered well.  The soil should be very acidic, moist and sandy. Irrigate regularly.  Its delicate, feathery foliage is sage green when new, turns to copper-gold in autumn and then falls with the first frosts, leaving the tree "bald."

It is a large, slow-growing, and long-lived tree. It typically grows to heights of 35–120 feet (10–40 m) and has a trunk diameter of 3–6 feet.  Plant them at least 50 ft apart if you plan a group to allow “air” between the trees.  The tallest know specimen can be found near Colonial Williamsburg, Virginia, with a height of 145 ft. The oldest known living specimen, in Bladen County, North Carolina, is over 1,620 years old.

Bald Cypress Shade trees are available in Nurseries and garden centers, starting at ca. $70 for an 8 gallons pot. It might grow from 1 to 2 ft per year in favorable conditions.

Teo Spengler from SFGate explains how to grow them from seed - if you have patience:
Harvest bald cypress fruits on the ground beneath the tree in autumn. Look for round cones that have not opened. Store them in a warm location to dry for several weeks.

Break the cones into small pieces, each containing one or more seeds. Separating the seeds from the sappy cone segments is very hard, but you can plant them together.

Fill the bottom one-half of a plastic bag with wet sand. Place the seeds and cone pieces into the bag with the sand. Store the bag in a refrigerator for two to four months at a temperature between 30 and 50 degrees Fahrenheit.



Fill a planting tray with wet sphagnum moss. Remove the plastic bag from the refrigerator, and take the seeds and cone pieces from the plastic bag. Sow the seeds and cone pieces in the wet sphagnum moss. Press each seed and cone piece until it is 1/2 inch below the surface of the moss. Sow 10 seeds for every one tree you wish to grow. The germination rate for bald cypress seeds varies greatly. Saturate the moss with water, but do not flood the seeds. Maintain the wet condition of the planting medium until the seeds germinate, which generally takes one to three months.

Tropical Plant Curcuma - the New Garden Star




Curcuma is an eye-catching perennial with a tropical feel. It pairs nicely with other tropical plants, like hibiscus and elephant ears. The plant prefers plenty of water so it would be a nice companion planting on the same watering schedule as the elephant ear.

The name comes from the Sanskrit kuá¹…kuma, referring to turmeric. Turmeric has been used in India since ancient times as a substitute for saffron and other yellowish pigments.

For garden planting, choose a location that has a fertile, moist soil with good drainage that receives a little early morning sun or bright filtered shade all day.  Tubers should be planted about 1.5'' (4cm) deep and completely covered by soil to remain moist for good sprouting.  Optimal temperature is between 20-30 degrees Celsius.

Winter Care of Curcuma in Cold Climates
Costa Farm’s website gives this advice: “If you live in a cold-winter area, you’ll need to bring your Curcuma indoors to protect it from the chilly conditions. Curcuma needs to go dormant, so you can’t treat it like a houseplant. Rather, you’ll need to store the tubers in a cool, dry place."

"For Curcuma planted in the ground, carefully dig the tubers in fall, when the plant’s foliage begins to turn yellow. Gently clean loose soil from the tubers, then let them dry in a warm, sunny place for a day or so. Once the tubers are dry, store them in a container with coarse sand or peat moss. Don’t seal the container -- let it breathe. It’s best to store Curcuma tubers in a cool place (50F/10C) over winter. You don’t want the tubers to completely dry up over winter, sprinkle just a small splash of water in the sand/moss periodically."

For Curcuma in pots, you can stop watering the container once the foliage starts to go yellow. Let the potting mix dry, then store the entire pot in a cool place (50F/10C) for winter. Sprinkle just a bit of water in the pot a couple of times over winter so the tubers don’t completely dry out. Bring your Curcuma back outdoors to a shaded or partly shaded spot in spring after all danger of frost has passed.
