Oncidopsis (Burrageara) Nelly Isler

Burrageara Nelly Isler 1 Orchid Nature

The Oncidopsis (Burrageara) Nelly Isler is a sympodial epiphyte orchid hybrid. It was registered in 1995 and created by J. Isler as a cross between Oncidopsis Stefan Isler and Miltoniopsis Kensington. This orchid can also be found under the name Burrageara, but recent classification places this orchid under the Oncidopsis hybrids family. The Nelly Isler is well known for its wonderful red blooms, but also for its fussiness when it comes to less than ideal conditions.

Flowers

The blooms remind of Miltoniopsis orchids, with longer narrower petals and broad lip. The flower can reach about 10 cm in diameter, while the coloration can vary from deep red, to pale red with a white tessellation. The lip has a yellow center and continues with a cascading pattern. When seen in person, the flowers of the Nelly Isler are quite striking and majestic.

The blooms are displayed on a thin flower spike which can reach 30 cm in length and can hold up to 6-10 flowers. The Nelly Isler is a fragrant orchid and opinions vary regarding its scent. The fragrance reminds of lemon fruit, which is quite delightful for most people, but for some it can be too acidic and sour. The fragrance is also quite strong and has the potential to fill up a room if not properly ventilated. The orchid releases the strongest scent in the morning hours and by evening the fragrance is gone.

The flowers last about 4 to 6 weeks, depending on environment. After the blooms fall, usually the orchid starts to produce new pseudobulbs. The spikes can be cut near the base after the blooms drop, as they will not rebloom, or produce plantlets.

It seems that in high temperatures the Nelly Isler does not produce the most desirable blooms. They appear to be tinier or slightly deformed and the white tessellation is very striking. As temperatures are cooler and more to its liking, the blooms will be a deeper red and have a nicer overall aspect.

This orchid can bloom multiple times in one year. Usually, with every maturing pseudobulb a flower spike can be produced. In some cases the orchid can produce 2 flower spikes emerging from each side of the pseudobulb.

Appearance

The pseudobulbs are about 4-6 cm in height and about 3 cm in width, with an oval shape. The normal color for this orchid is light green.  The leaves are long and slender, measuring about 30 cm in length and about 2-3 cm in width. The leaves are prone to obtain an accordion shape if the orchid is kept too dry and in too low humidity.

The roots are thin and healthy roots are white, but as they age, they can turn green when wet. When in active growth they have bright green tips. New growths usually appear from between the last exterior leaves and take between 6 to 9 months to fully mature.

Propagation of this orchid can be done through division, each division should have at least 3 fully grown pseudobulbs for a fast growth further on.

Soft spots: shriveled pseudobulbs if kept too dry, accordion leaves if kept too dry and in low humidity, this being the major drawback of this hybrid, as it is very sensitive to low humidity.

Overall the Oncidopsis Nelly Isler is a moderately hard orchid to grow. In humid environments with cool temperatures it can thrive, while in dry environments, or high temperatures it can be a nightmare.
