Sugar-apple

Annona squamosa (also called sugar-pineapple or sweetsop) is a species of Annona native to the tropical Americas and widely grown in Colombia, El Salvador, India, Pakistan and the Philippines. Its exact native range is unknown due to extensive cultivation, but thought to be in the Caribbean; the species was described from Jamaica.

It is a semi-evergreen shrub or small tree reaching 6–8 meters (20–26 ft) tall. The leaves are alternate, simple, oblong-lanceolate, 5–17 cm (2.0–6.7 in) long and 2–5 centimeters (0.79–2.0 in) broad. The flowers are produced in clusters of 3-4, each flower 1.5–3 cm (0.59–1.2 in) across, with three large petals and three minute ones, yellow-green spotted purple at the base.

The fruit is usually round, slightly pine cone-like, 6–10 cm (2.4–3.9 in) diameter and weighing 100–230 g (3.5–8.1 oz), with a scaly or lumpy skin. There are variations in shape and size. The fruit flesh is sweet, white to light yellow, and resembles and tastes like custard. The edible portion coats the seeds generously; a bit like the gooey portion of a tomato seed. Sugar-apple has a very distinct, sweet-smelling fragrance. The texture of the flesh that coats the seeds is a bit like the center of a very ripe guava (excluding the seeds). It is slightly grainy, a bit slippery, very sweet and very soft. The seeds are scattered through the fruit flesh; the seed coats are blackish-brown, 12–18 mm (0.47–0.71 in) long, and hard and shiny.

There are also new varieties being developed in Taiwan. The atemoya or "pineapple sugar-apple", a hybrid between the Sugar Apple and the Cherimoya, is popular in Taiwan, although it was first developed in the USA in 1908. The fruit is similar in sweetness to the sugar apple but has a very different taste. Like the name suggests, it tastes like pineapple. The arrangement of seeds is in spaced rows, with the fruit's flesh filling most of the fruit and making grooves for the seeds, instead of the flesh only occurring around the seeds. Unlike other Annona fruits, the Sugar Apple has segmented flesh.

Hippeastrum


Hippeastrum /ˌhɪpiːˈæstrəm/ is a genus of about 90 species and 600+ hybrids and cultivars of bulbous plants in the family Amaryllidaceae, subfamily Amaryllidoideae, native to tropical and subtropical regions of the Americas from Argentina north to Mexico and the Caribbean. Some species are grown for their large showy flowers. For many years there was confusion amongst botanists over the generic names Amaryllis and Hippeastrum, one result of which is that the common name "amaryllis" is mainly used for cultivars of this genus, which are widely used as indoor flowering bulbs. The generic name Amaryllis applies to bulbs from South Africa, usually grown outdoors.

Amaryllis


Amaryllis is a bulbous plant, with each bulb being 5–10 cm in diameter. It has several strap-shaped, green leaves, 30–50 cm long and 2–3 cm broad, arranged in two rows. The leaves are produced in the autumn or early spring in warm climates depending on the onset of rain and eventually die down by late spring. The bulb is then dormant until late summer. The plant is not frost-tolerant, nor does it do well in tropical environments since they require a dry resting period between leaf growth and flower spike production.

From the dry ground in late summer (August in zone 7) each bulb produces one or two leafless stems 30–60 cm tall, each of which bears a cluster of 2 to 12 funnel-shaped flowers at their tops. Each flower is 6–10 cm diameter with six tepals (three outer sepals, three inner petals, with similar appearance to each other). The usual color is white with crimson veins, but pink or purple also occur naturally. The common name "naked lady" stems from the plant's pattern of flowering when the foliage has died down.

The species was introduced into cultivation at the beginning of the eighteenth century. They reproduce slowly either by bulb division or seeds and have gradually naturalized from plantings in urban and suburban areas throughout the lower elevations and coastal areas in much of the West Coast of the USA since these environments mimic their native South African habitat.

Many bulbs sold as Amaryllis and described as 'ready to bloom for the holidays' actually belong to the allied genus Hippeastrum, despite being labeled as 'Amaryllis' by sellers and nurseries. Adding to the name confusion, some bulbs of other species with a similar growth and flowering pattern are also sometimes called this plant's common name "naked ladies". Some of those species have their own more widely used and accepted common names, such as the Resurrection Lily (Lycoris squamigera).
