Here is my Habenaria radiata, aka Pecteilis radiata - egret orchid from 2016. It did not survive the 2016-2017 winter, much to my same. It was potted in a lovely Bunzan pot, beautiful blue glaze with yellow highlights.
How to grow and things to do different next time.
Potting mix, mine worked well enough. blend of fine fir bark for seedling orchids, Kanuma, perlite, chopped long fiber sphagnum, a small portion of fine sand (play sand) top dress with a layer of sphagnum moss, then plant living ''crack in the sidewalk moss''. They want a mildly acidic, water retentive mix that breathes well, allowing good air penetration.
Water - these never want to dry out completely - in nature they come from edges of bogs and swampy areas. Usually in grassy hummocks, where the bulb is above the water but roots can head down to get into water. They are somewhat sensitive to excess Calcium, use rainwater as much as possible. If you use tap water, try to follow up with rain water the next day. If you use liquid fertilizer, use the one for acid loving trees and shrubs. Organic fertilizers should be no problem. Keep fertilizer solution dilute, one half or one quarter strength.
Sun, should have 3 to 8 hours of direct sun daily. Morning sun is best.
Leave outdoors until light frost. Then either unpot bulbs, pack in damp moss and refrigerate for winter in a plastic bag or put whole pot in the refrigerator. Replant, repot or set outside after danger of frost has past in spring. Hardy through zone 8, possibly into zone 7.
Things to do different. - most important. This orchid is thin and grassy, needs support when blooming. In order to get flower stems to stand up straight without unnatural props, stakes, bamboo skewers or whatever, you should plant a thin, not too aggressive sedge or grass in the pot with the orchid. The blades of grass will provide support for the orchid flower stems. The grass roots will help move water (requiring more water) which will keep the mix fresher. The grass will shade the leaves of the orchid a little, allowing to give the orchid more direct sun. They really do want sun. A larger pot with a mix of ferns and grasses would result in hardier growth of the orchid. Adding grasses or sedges also makes the planting a true kusamono. Kusamono means grass planting.
