Loquat – An Attractive Small Tree That Bears Tasty Fruit
Loquat trees provide nice fall color with creamy yellow buds and white flowers on their long terminal panicles. These small (20 to 35 ft. tall) evergreen trees are native to China and first appeared in Southern landscapes in the late 19th Century. They are grown commercially in subtropical and Mediterranean areas of the world and small production acreage can be found in California. They are cold tolerant down to temperatures of 8 degrees Fahrenheit, but they will drop their flowers or fruit if temperatures dip below 27 degrees Fahrenheit.

Leaves – The leaf configuration on loquat trees is classified as whorled. The leaf shape is lanceolate and the color is dark green with a nice soft brown surface underneath. These features help give the trees their tropical appearance.
Flowers – 30 to 100 flowers can be present on each terminal panicle. Individual flowers are roughly half an inch in diameter and have white petals.
Fruit – What surprises most people is that loquats are more closely related to apples and peaches than any tropical fruit. Fruit are classified as pomes and appear in clusters ranging from 4 to 30 depending on variety and fruit size. They are rounded to ovate in shape and are usually between 1.5 and 3 inches in length. Fruit are light yellow to orange in color and contain one to many seeds.

Propagation – Loquat trees are easily propagated by seed, as you will notice as soon as your tree first bears fruit. Seedlings pop up throughout yards containing even just one loquat tree. It is important to note that the trees do not come true from seed and they go through a 6- to 8-year juvenile period before flowering and fruiting. Propagation by cuttings or air layering is more difficult but rewarding, because vegitatively-propagated trees bear fruit within two years of planting. Sometimes mature trees are top-worked (grafted at the terminal ends of branches) to produce a more desirable fruit cultivar.
Loquat trees are hardy, provide an aesthetic focal point to the landscape, and produce a tasty fruit. For more information on growing loquats and a comprehensive list of cultivars, please visit the UF EDIS Publication: Loquat Growing in the Florida Home Landscape.
Pomegranates in the Panhandle
Last week at the Panhandle Fruit and Vegetable Conference, Dr. Ali Sarkhosh presented on growing pomegranate in Florida. The pomegranate (Punica granatum) is native to central Asia. The fruit made its way to North America in the 16th century. Given their origin, it makes sense that fruit quality is best in regions with cool winters and hot, dry summers (Mediterranean climate). In the United States, the majority of pomegranates are grown in California. However, the University of Florida, with the help of Dr. Sarkhosh, is conducting research trials to find out which varieties do best in our state.
In the wild, pomegranate plants are dense, bushy shrubs growing between 6-12 feet tall with thorny branches. In the garden, they can be trained as small single trunk trees from 12-20 feet tall or as slightly shorter multi-trunk (3 to 5 trunks) trees. Pomegranate plants have beautiful flowers and can be utilized as ornamentals that also bear fruit. In fact, there are a number of varieties on the market for their aesthetics alone. Pomegranate leaves are glossy, dark green, and small. Blooms range from orange to red (about 2 inches in diameter) with crinkled petals and lots of stamens. The fruit can be yellow, deep red, or any color in between depending on variety. The fruit are round with a diameter from 2 to 5 inches.

A common commercial variety, ‘Wonderful’, is widely grown in California but does not perform well in Florida’s hot and humid climate. Cultivars that have performed well in Florida include: ‘Vkusnyi’; ‘Crab’; ‘Mack Glass’; and ‘Ever Sweet’. Pomegranates are adapted to many soil types from sands to clays, however yields are lower on sandy soils and fruit color is poor on clay soils. They produce best on well-drained soils with a pH range from 5.5 to 7.0. The plants should be irrigated every 7 to 10 days if a significant rain event doesn’t occur. Flavor and fruit quality are increased when irrigation is gradually reduced during fruit maturation. Pomegranates are tolerant of some flooding, but sudden changes to irrigation amounts or timing may cause fruit to split.

Pomegranates establish best when planted in late winter or early spring (February – March). If you plan to grow them as a hedge (shrub form), space plants 6 to 9 feet apart to allow for suckers to fill the void between plants. If you plan to plant a single tree or a few trees then space the plants at least 15 feet apart. If a tree form is desired, then suckers will need to be removed frequently. Some fruit will need to be thinned each year to reduce the chances of branches breaking from heavy fruit weight.

Anthracnose is the most common disease of pomegranates. Symptoms include small, circular, reddish-brown spots (0.25 inch diameter) on leaves, stems, flowers, and fruit. Copper fungicide applications can greatly reduce disease damage. Common insects include scales and mites. Sulfur dust can be used for mite control and horticultural oil can be used to control scales.
New Flavors with Edible Flowers
More and more homeowners are incorporating edible plants into their home landscape in order to enjoy the fresh taste of fruits and vegetables. Another trend to consider this coming cool season is to start a few common flowers that can serve as flavor enhancements for many of your dishes.
There are numerous plants that we commonly grow that have edible flowers but before striking out on your first taste test, be sure to research first. Always remember the common saying that every flower is edible once. Find a reputable reference guide from a friendly neighborhood Extension office for a list of common edible flowers, then be ready to start from seeds. It is best not to purchase transplants from an ornamental nursery unless you are sure of all the treatments for that plants. Nurseries are often selling these for beauty alone, not with intention that they will be eaten.
Here are a few edible flowers to try:
Pot marigold or Calendula is a wonderful cool season flower on its own. Brightly colored orange or yellow flowers improve the drab colors of our cool season and plants are sturdy annuals for borders, mass plantings, or in containers. Petals have a peppery flavor and add spice to salads and sandwiches. You may also add flowers to soups, fishes and butters for added coloring. Calendula petals can be a saffron substitute.

The well known dianthus is a great transition plant as our days cool and warm up again the spring. Use as front of the border plantings or in containers as a filler. When harvesting petals of dianthus, you will want to remove the white petal base which is a little bitter. The flavor is a little more delicate than cloves so you can add petals to punches, desserts, and fruit salads.
If you like a little more spice, try nasturtiums. We often plant these after the last frost and they grow until we get too hot. Since our fall weather is so unpredictable, you may be able to start some seeds for a fall planting and have flowers before our first cold spell. Either way, nasturtium flowers are often sliced for salads and sandwiches as a mustard or pepper substitute. You can also mince flowers to add to a butter. If you let some flowers go to seed, collect the unripe seeds to make a caper substitute vinegar.

If you are going to use edible flowers from your garden remember to keep all non food labeled pesticides away from plants. Harvest flowers at their peak after the dew dries. Separate petals from other flower parts and if you have allergies be sure to remove any pollen. Place flowers in a moist towel in the refrigerator if you will not use them immediately. Rinse carefully so not to damage tender petals.
There are many other ornamental plants that offer edible flowers you may want to consider growing in the future. These flowers not only enhance the look of the dish but can offer unique flavoring from a locally grown source – your own backyard.
Eggplants Aren’t Always Purple

Mid-summer in the Panhandle vegetable garden is prime time to be offering up a great crop of eggplant. This is one of my favorite summertime fruits to grow! (Yes, it is botanically speaking a ‘fruit’ and not a ‘vegetable’.)
Many home gardeners are familiar with the standard ‘Black Beauty’ variety that produces large plump fruit, but there are many other eggplant varieties to try. Take a look at Heirloom Eggplant Varieties in Florida to get some ideas. Gardeners can access dozens of varieties through online seed vendors. Eggplants can be dark purple, purple-striped, pale purple, white, green and even orange. They come in all shapes and sizes and all are delicious to eat, j make sure you learn when to harvest the variety you choose for optimum enjoyment. For example, the Turkish Orange illustrated in the photo should be picked before it turns all orange to avoid any bitterness.
In the panhandle, plant eggplant anytime February through August for harvest late spring through fall. Eggplant is in the nightshade (Solanaceae) family along with tomato, pepper, and potato. Keep that in mind when you are planning your garden for next year to avoid planting members of the same family in the same spot year after year, which encourages recurring disease and pest issues.
Eggplant loves rich soil and benefits from regular fertilization with commercial fertilizers or applications of compost. Eggplant is considered a long season crop and one can expect harvest to begin around 90-110 days after planting seed or 75-90 days if setting out transplants. Eggplant is, in general, more drought tolerant than tomato but it is still good practice keep them consistently moist and avoid letting them completely dry out. Also, while eggplant is self-pollinating, it is an excellent pollinator plant, as many species are attracted to the pretty blooms.
Eggplant is also relatively easy to grow, not generally requiring pruning or staking. Many of the same pests of tomato and pepper will also be attracted to eggplant. Be on the lookout for tomato hornworm and other caterpillar pests. For natural pest control methods, consult Natural Products for Managing Landscape and Garden Pests in Florida
