About Chinese Ground Orchid

Bletilla striata · also called Hardy Orchid, Urn Orchid · flowering

Bletilla striata is a terrestrial orchid native to China and Japan, one of the hardiest orchids in cultivation. It produces upright stems bearing several purple-pink, lily-like flowers in late spring to early summer. Unlike most orchids, it tolerates outdoor conditions in temperate gardens. Orchidaceae; considered pet-safe.

Plant type: flowering

Watch for — Failure to flower: Insufficient light or premature transplanting of underdeveloped pseudocorms are the common causes; allow clumps to establish for 2-3 years before dividing.

The reasons chinese ground orchid isn't blooming

Almost every non-blooming chinese ground orchid traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding chinese ground orchid a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get chinese ground orchid to flower

Maximise sun. Give chinese ground orchid the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for chinese ground orchid and get the feeding right with the chinese ground orchid fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Chinese Ground Orchid flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

For everything else this plant needs day to day, see the full chinese ground orchid care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Chinese Ground Orchid blooming — frequently asked questions

Why won't my chinese ground orchid flower?

Chinese Ground Orchid blooms on the season's growth given enough sun, warmth and the right feed — there is no cold or photoperiod trick, just good growing conditions and a bloom-leaning feed. The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
