Oleander seeds

1
Fill 4-inch nursery pots with a peat-based, soil-less growing mixture. Add water until it feels very moist in the top two inches. Press one oleander seed onto the surface, and cover it with a thin layer of medium-grit perlite.

2
Place the pots inside an unventilated cold frame in full sun. Warm the pots to between 65 and 70 degrees Fahrenheit with a propagation mat or greenhouse warming coil. Do not lower the temperature at night during the germination process.

3
Moisten the growing mixture daily to ensure the oleander seeds never fully dry out. Water with a spray bottle or a garden hose with a misting nozzle. Avoid pouring water into the pots since a strong stream will dislodge the seeds.

4
Watch for germination in two to three weeks. Remove the propagation mat once that happens, and crack open the cold frame to increase air circulation around the oleander seedlings. Water whenever the growing mixture feels barely damp in the top inch.

5
Move the seedlings to a sheltered area outdoors after the last spring frost. Transplant them into 6-inch pots filled with standard potting soil once they grow to 3 inches high. Grow them under light shade and provide one inch of water weekly during their first summer.

6
Transplant the oleanders into a permanent bed in autumn. Choose a sunny site with fast-draining soil. Space multiple shrubs approximately 5 feet apart. Keep them well-watered during their first year in the garden. - In Stock

This is a beautiful shrub, which covers itself in red flowers for a long period in summer.

Oleander grows to 2 to 6 m (6.6 to 19.7 ft) tall, with erect stems that splay outward as they mature; first-year stems have a glaucous bloom, while mature stems have a grayish bark. The leaves are in pairs or whorls of three, thick and leathery, dark-green, narrow lanceolate, 5 to 21 cm (2.0 to 8.3 in) long and 1 to 3.5 cm (0.39 to 1.38 in) broad, and with an entire margin. The flowers grow in clusters at the end of each branch; they are red,2.5 to 5 cm (0.98 to 1.97 in) diameter, with a deeply 5-lobed fringed corolla round the central corolla tube.

They are often, but not always, sweet-scented. The fruit is a long narrow capsule 5 to 23 cm (2.0 to 9.1 in) long, which splits open at maturity to release numerous downy seeds.

Oleander is a vigorous grower in warm subtropical regions, where it is extensively used as an ornamental plant in parks, along roadsides, and as a windbreak.

It will tolerate occasional light frost down to -10 C (14F)., though the leaves may be damaged. The toxicity of Oleander renders it deer-resistant.

The plant is tolerant of poor soils, salt spray, and sustained drought, although it will flower and grow more vigorously with regular water. Nerium Oleander also responds well to heavy pruning, which should be done in the autumn or early spring to keep plants from becoming unruly.

In cold-winter climates Oleander can be grown in greenhouses and conservatories, or as potted indoor plants that can be kept outside in the summer.

Oleander flowers are showy, profuse, and often fragrant, which makes them very attractive in many contexts. Over 400 cultivars have been named, with several additional flower colors not found in wild plants having been selected, including red, pink, yellow, and salmon; white and a variety of pinks are the most common. Double flowered cultivars like 'Mrs Isadore Dyer' or 'Mont Blanc' are enjoyed for their large, rose-like blooms and strong fragrance.

Many dwarf cultivars have also been developed, which grow only to about 10' at maturity. In most Mediterranean climates they can be expected to bloom from April through October, with their heaviest - In Stock
