Like many other edible members of the Solanaceae family, eggplantsare an excellent addition to the home garden. These large and heavy yieldingplants reward warm season gardeners with delicious, fresh eggplant fruit. Whilediversity among different varietiesof eggplant may not be as apparent as in other plants, openpollinated varieties and newly introduced hybrids allow growers to find plants thatwill thrive in their home gardens. One hybrid, called ‘Orient Charm,’ producesbeautiful pinkish-purple oblong fruits. Read on for tips on growing OrientCharm eggplants in the garden.
So, what is an Orient Charm eggplant? These plants are ahybrid cultivar of Asian eggplant. The oblong fruits are generally pinkishpurple in color and reach sizes of around 8 inches (20 cm.). Maturing in aslittle as 65 days, this variety of eggplant is an excellent choice forgardeners with short growing seasons.
The process of growing Orient Charm eggplants is verysimilar to that of growing other varieties. First, growers will need to decidehow they want to start their eggplant. Orient Charm may be available asseedlings at garden centers in early spring. However, it is more likely thatgardeners will need to start these plants from seed themselves.
Seeds can be started indoors using seed starting trays andgrow lights about 6-8 weeks before the last predicted frost date of the season.To sow, fill the trays with seedstarting mix. Add one or two seeds to each cell in the seed tray.Place the tray in a warm location and keep it consistently moist untilgermination takes place.
For many, germination may be improved with the help of aseed starting warming mat. Once the seeds have germinated, grow the plants in asunny window until all chance of frost has passed in the garden. Lastly, beginthe process of hardeningoff the plants and transplantingoutdoors into their growing location.
Select a well-draining and amended garden bed which receivesfull sunlight, or plant in a deep container. Consistent and frequent wateringthroughout the season will also help to ensure even growth from plants. Asgrowth continues, heavy bearing plants may require staking or the support of atrellis to remain upright.

Eggplant is thought to have been cultivated in India and China more than 1,500 years ago. A Chinese cookbook from the fifth century mentions eggplant, and ancient Chinese brides were required to have eggplant recipes as part of their dowry.
Colonialization and trade brought the fruit (though most commonly regarded as a vegetable) to Africa, Europe, and eventually to America in the 1800s.
Part of the nightshade (Solanaceae) family, eggplant was once thought to be poisonous. When eggplant arrived in Italy, it was called the “mad apple” and reputed to make people who ate it go crazy. The leaves and flowers, when consumed in large quantities, can be poisonous, but not the fruit.
Eggplant is related to tomatoes, potatoes, and peppers, and goes by many names including eggfruit, aubergine, brinjal, tomato-fruited eggplant, gilos, guinea squash, mad apple, and nasubi.
Types & Varieties
Eggplant comes in two basic families: Solanum melongena, the traditional eggplant with a solid, fleshy inside, and Solanum integrifolium and Solanum gilo which are more like tomatoes with a soft inside and hence called “tomato-fruit eggplant.”
Common eggplant is dark purple or black, 6 to 9 inches long, bulb-shaped, and 3 to 4 inches wide at the base. Varieties include Black Bell, Black Beauty, and Black Magic. Other large-fruit varieties include Dusky, Epic, Classic, Burpee Hybrid, and Ghostbuster.
Eggplant also comes in elongated varieties such as the Ichiban, Slim Jim, and Little Fingers. There are several popular Asian cultivars including Orient Express, Orient Charm, Calliope, and Machiaw, as well as ornamental varieties including the Easter Egg.
Asian varieties have softer skin and ornamental varieties are small, oval-shaped, and often whitish in color. Tomato-fruit eggplant can range in color from green to red to orange, and even be striped or bicolored.
As a crop, eggplant loves heat and full sunlight but does not like frost. It grows best in rich sandy or loamy well-drained soils with a pH between 5.5 and 7. Plants require several months of sun to bear fruit, so seedlings should be planted well before the last frost is expected.
Plants prefer temperatures between 70 and 85°F. Flowering and fruiting can slow or stop at temperatures below 60°F and above 95°F.
Star-shaped flowers will grow on thick stems and self-pollinate, producing various sizes of purple, black, and sometimes white or striped fruit, depending on the variety.
Mature plants can reach 8 feet in height. Fruit can be harvested when skin is firm and shiny, and is edible from about one-third of full size through maturity. Too-mature fruit can become hard and bitter.
To produce larger eggplant, remove other fruit to allow the plant to send nutrients to just one or two. Harvesting by hand with clippers is best typically the cap and a short piece of stem are left on.
Pests & Diseases
Eggplant is susceptible to several pests and diseases including flea beetles, aphids, and spider mites that damage leaves in young plants and can impact yield. Pests can be managed with insecticide and row covers.
Diseases include verticillium wilt which causes yellowing and wilting and can stunt or kill plants, as well as postharvest diseases such as black or grey mold rot and hairy rot that can damage fruit.
Eggplant should be cooled quickly after harvest (forced air or hydrocooling) to maintain moisture. Chill to 50°F and 90 to 95% relative humidity to maintain freshness for up to 2 weeks.
Cooling below 50°F for storage or transportation can result in chilling injury, leading to pitting or browning of flesh and seeds. Normal decay after 2 weeks occurs as loss of surface sheen, wrinkling, browning of the stem or top, and spongy pulp tissue.
Waxed cartons can reduce moisture loss and decay. Stacking cartons and overpacking can cause bruising and decay.

Eggplant are divided into U.S. Fancy, U.S. No. 1, and U.S. No. 2 grades: U.S. Fancy should exhibit similar varietal characteristics (except as a mixed or specialty pack the same is true for U.S. No. 1), fruit should be well colored and shaped, firm, clean, and free from decay or worn holes and injury from scars, freezing, disease, insects, or mechanical means.
For U.S. No 1, eggplant should be fairly well colored and shaped, firm, clean, and free from the above decay and injuries U.S. No. 2 should be firm, free from decay, and with no serious damage from freezing, disease, insects, or mechanical injury.
Generally speaking, the percentage of defects shown on a timely government inspection certificate should not exceed the percentage of allowable defects, provided: (1) transportation conditions were normal (2) the USDA or CFIA inspection was timely and (3) the entire lot was inspected.

There are no good arrival guidelines for this commodity specific to Canada U.S. guidelines apply to shipments unless otherwise agreed by contract.
• There is no requirement for the color of the calyx a calyx turning brown and dry is not a defect
• For U.S. No. 1, eggplant must be reasonably uniform in size: the weight of the smallest fruit is not less than half the weight of the largest
• Brown discoloration is scored as a defect when affecting more than 10% of the surface
• Shriveling is scored as a defect and serious damage when affecting more than 5% of the surface.
