關於雙囊石斛

Dendrobium bigibbum, the Cooktown Orchid from northeastern Australia, bears up to 20 reddish-purple blooms on arching spikes — the wild ancestor of many Dendrobium phalaenopsis hybrids.

開始照料雙囊石斛前需要了解的7件事

1. 1Light & Placement

   This species loves strong light. Give it light shade only from direct midsummer sun, and plenty of sunlight the rest of the year. Native to the tropical lowlands, it dislikes cold, so keep it on a warm indoor windowsill in winter, away from drafts and frost.

2. 2Watering by Season

   During the growing season, water thoroughly whenever the medium has dried out. In winter, hold back on water and let the plant rest, and don't resume watering until new shoots have grown to about 5 to 7 cm; this is considered the key to getting it to flower.

3. 3Well-Draining Media

   As an epiphytic orchid, it prefers airy, fast-draining media such as sphagnum moss or bark chips. Good airflow around the pot also helps prevent the roots from staying too wet.

4. 4When to Repot

   Because the canes grow long over time, it's time to repot once they outgrow the pot or the medium starts breaking down. Use a fast-draining medium such as bark in a fairly small pot, and repot around the time new growth starts to emerge.

5. 5Protecting from Cold

   Native to the warmer parts of northeastern Australia, this orchid has limited cold tolerance. Bring it indoors to a bright spot once temperatures start dropping rather than leaving it outside.

6. 6Encouraging Blooms

   Letting the plant rest fairly dry in winter helps flowers form on both leafy and leafless canes. Waiting until new shoots reach 5 to 7 cm before resuming watering, and building up strong growth in good light during the growing season, also supports blooming.

7. 7Choosing a Healthy Plant

   Look for a plant with plump, firm canes, which is a good sign of strong growth. Leaves free of damage or dark spots, along with roots that are well anchored in the medium, make for an easier start.

雙囊石斛的常見問題

Q.Can beginners grow this orchid?

A.It's generally considered suited to growers with some experience, since temperature and watering need a bit of attention. Once you learn the basics, it's a manageable step up for anyone who has grown orchids before.

Q.How large does it grow?

A.The canes can reach roughly 20 to 120 cm, with flower spikes around 20 to 40 cm and individual blooms about 3 to 7 cm across. A more mature, well-grown plant tends to produce more flowers.

Q.How long can I keep enjoying this plant?

A.It's a perennial orchid that can be grown for many years by dividing the clump as it grows. Detailed lifespan data is limited, but with good care it can be maintained and renewed season after season.

Q.What do the flowers look like?

A.Rounded, reddish-purple flowers cluster along arching flower spikes, with as many as twenty blooms on a single spike. The full clusters give the plant an especially showy look when in bloom.

Q.Is this the same as a Dendrobium phalaenopsis hybrid (Den-Phal)?

A.No, it's a distinct species. Dendrobium bigibbum is one of the wild ancestors behind Den-Phal type hybrids, so while related, it's considered separate from them.
