With a little care, it's sure to be a show-stopper in any garden.
Osa pulchra is an extraordinary, rare endemic flowering plant found in Costa Rica. It is an ideal choice for tropical gardens, greenhouses and other outdoor spaces, as it grows to a substantial size (between 5-20 ft, or 1.5-6m) and produces masses of sweet-smelling, white or off-white flowers throughout the year. These flowers attract butterflies and hummingbirds, making it the perfect ornamental choice for those looking to invite wildlife into their garden.
Easy to care for, Osa pulhcra prefers to be grown in sheltered, warm environments and can thrive in either full sun or semi-shade. It should be watered regularly and soils should be kept moist but not overly damp. For best results, use a general-purpose or liquid fertilizer every two weeks and undertake regular pruning to promote growth and preserve its form, but be careful not to over-prune, as this will reduce flowering potential.
USDA Zones 9-11 are the ideal climate for Osa pulchra and, in colder regions, it is possible to grow the plant in large containers that can be brought indoors over the winter. It is important to check for insect or disease attack if foliage turns yellow, as this can occasionally happen.
In conclusion, Osa pulchra is an exquisite ornamental plant that is easy to look after and can add beauty and aroma to any sized garden. With the right care and conditions, it will provide a stunning and long-lasting display.
