Orchid & Succulent Arrangements
These one-of-a-kind arrangements are exclusively created by Sandra Charles, Orchid Greenhouse volunteer, and available for sale at the San Mateo Arboretum Society Orchid Greenhouse. Various types of orchids are accented with succulents & planted in Canary Date Palm Tree frond base/planter.
Den. Victoria-Reginae: Is a cool to intermediate temperature plant, which apparently requires no rest. Superb blue-lavender flowers are produced at varying times of the year when mature. These plants can lose their leaves during the fall winter months this is normal. The growths are very narrow at the base and the plant grows in a pendulous way in nature.
Stanhopea ‘Wardii’: Bloom period is fall to winter with 3 to 10 flowers that may last 2-4 days. Flowers are 5″ wide and very pleasant and clean fragrant. Plant should be grown in shade, kept warm and watered regularly. Plants are usually grown in baskets in sphagnum moss or in medium fir because of its pendant flowers. The fragrance of the Stanhopea is rather intense lemon/citrus at first.
Pleione: Are a small group of cool and alpine growing orchids which are the easiest orchids to grow and propagate. The flowers are large, delicately colored and exotic looking. They are all deciduous and need a rest during the winter at which time the round squat bulbs should be stored on a shelf in the greenhouse or a cool room with diffused light. They like good light during the growing season and can be left out doors during the summer. Water them weekly during the growing season between February and October.
Phalaenopsis aka Phals are one of the easiest orchids to grow in the home. Watering will depend on the potting medium. Bark retains less water than moss. If potted in bark watering once a week is generally sufficient. If your plant is potted in moss, water when the top feels dry. They grow best in an east window and can be grown in a south or west window if protected by a sheer curtain. Phals like the same temperatures we do – above 60º F at night & a range of 70º F to 80º F or higher during the day. Feed weakly (half strength of balanced fertilizer) weekly works well. When the blooms are finished, cut the spike down to the level of the leaves leaving two nodes (those little brown lines on the stem below where the flowers were) on the stem. The plant will bloom with larger flowers and a strong stem within a year.
Oncidium orchids are generally easy to grow, adapting well to intermediate temperatures and tolerating an occasional missed watering without damage. They are great for beginners and orchid experts alike. The brilliant and exquisite sprays/spikes of the larger oncidiums are dramatic and elegant. The flowers appear to be soft and delicate but the petals actually have a firm almost leathery feel to them.
Nepenthes: Popularly known as tropical pitcher plants or monkey cups, are a genus of carnivorous plants. Nepenthes attract & kill their prey through active production of sugary nectar and sweet scents. They like bright light without much direct sun. Do not allow them to dry out they benefit from moist media and occasional flooding to wash away any accumulated salts. After situating the plant, add a little water to the pitchers, about 1/2- 3/4 inch. Pitchers and leaves die naturally as the plant grows & these should be trimmed off, pruning the green stems back to encourage side shoots and a fuller plant.
Cattleya Patricia Lines (C. Barbara Billingsley x C. Bob Betts) 1957: Heirloom, great winter/spring bloomer with 6”+ white/yellow lip, excellent shape, very fragrant long lasting blooms, a good grower.
