Indoor jasmine plant: hoop, gardenia, or a tender twiner

Updated: 22 October 2026

The hoop arrived in flower, and a week later the buds are on the table. That is the usual failure of an indoor jasmine plant, and it is usually a move, a cold night, or dry air. Three plants get sold for this job. Madagascar jasmine is Stephanotis floribunda. Cape jasmine is a gardenia. Chinese jasmine is Jasminum polyanthum, and it is not in the set on the [jasmine plant comparison](/hub/ornamental-plants/jasmine-plant). Peter F. read the Carbeth hoop and gardenia pair on 20 October 2026, with RHS and BBC Gardeners' World notes. We did not grow them.

Three indoor plants, three genera

Stephanotis floribunda is a twining houseplant. The RHS rates it H1B, a minimum band of about 10–15°C. The Carbeth listing is that plant, about 40 cm in a 12 cm pot. Cape jasmine is Gardenia jasminoides, a shrub. The species profile is H1C. Crown Jewel and Kleim's Hardy are H3, about -5 to 1°C. The pair here is titled White Crown Jewels, which does not prove that cultivar, so do not copy H3 onto the ASIN. Chinese jasmine, Jasminum polyanthum, is a tender true jasmine and it is absent here. If the label says Jasminum, you are not holding the Madagascar jasmine. Which outdoor climber to buy instead is on the jasmine plant buying guide.

Keep the hoop still and humid

Leave a stephanotis where it is while the buds are opening. BBC Gardeners' World ties dropped blooms to a move, temperature swings, uneven watering, and dry air. The Carbeth listing conflicts on sun: the bullets say out of direct sunlight, and a product-care attribute says direct sunlight. Follow the bullets. The listing and BBC Gardeners' World both say a fortnightly high-potassium feed, such as tomato food, from April to October. The RHS says mist while in growth. A decorative pot in the photograph is not in the box. Stephanotis can set a pear-like fruit, and BBC Gardeners' World says that fruit is not edible. Do not leave the hoop on a patio through a British frost.

Cape jasmine wants acid compost and rainwater

The gardenia pair is the other Carbeth listing people add to an indoor search. The seller specifies a sheltered place, moist well-drained acidic soil, and partial sun, with creamy-white double flowers. An expected-height field says 25 cm. That is the field on the page, not a mature height. The bullets do not say whether you can grow it indoors. The RHS gardenia guide asks for ericaceous peat-free compost. In a hard-water area, use rainwater. Yellow new leaves are often overwatering or iron locked up by alkaline tap water. The plant-guide page wants about 21–24°C, with nights always above 16°C. Species gardenia is H1C. It will not twine.

Chinese jasmine is not the hoop in this set

Jasminum polyanthum is the tender true jasmine people hope the hoop will be. The RHS rates it H2, about 1 to 5°C. The growing guide says keep it above 13°C. A separate RHS conservatory page allows about 5–7°C. Both figures stay, because they are not the same floor. Frost is outside either version. This comparison does not sell polyanthum. If the label says Stephanotis, follow the BBC winter minimum and do not move it while it is in bud. Fence training stays on the how to grow jasmine page.

Common questions

Can Madagascar jasmine live in the garden all year?
No. Stephanotis floribunda is RHS H1B. It can spend a warm summer outside and is grown as a houseplant, with BBC Gardeners' World suggesting a winter minimum of about 13°C. A UK patio through frost will kill it. Bring it in before nights turn cold.
Why did the flowers drop a week after delivery?
BBC Gardeners' World links stephanotis bud drop to moving the plant, temperature swings, watering mistakes, and dry air. Reviews on the Carbeth hoop, 3.6 from 99 ratings, often describe a good arrival and then a drop within days or weeks. Leave it in a bright spot out of hot sun. A plant already dead in the box is a seller complaint.
What feed does the Carbeth listing name?
A fortnightly high-potassium feed from April to October. BBC Gardeners' World gives the same season and suggests a tomato food. That is for the growing and flowering months, not a winter dose on a resting plant. The decorative pot in the photos is not included with the hoop at about £19.99.
Is cape jasmine a climber?
No. Cape jasmine is a gardenia, a shrub. The Carbeth pair is two 9 cm pots, with acidic soil in the bullets. The plant-type field says Jasmine, which is the trade name, not a twining habit. It will not cover a trellis.
Can you use tap water on a gardenia?
In a hard-water area, the RHS says use rainwater. Alkaline tap water is a common reason new leaves turn yellow, along with overwatering. Use ericaceous peat-free compost. The listing states acidic, moist, well-drained soil and does not itself say rainwater, so the rainwater rule comes from the RHS, not from a bullet on this ASIN.
Is White Crown Jewels the RHS Crown Jewel cultivar?
The names are similar and the listing does not prove they are the same plant. RHS Crown Jewel is H3. This page does not apply that rating to the Carbeth pair. Treat the plants as young gardenias that need acid compost, and read the 25 cm figure as the listing's expected-height field only.
What temperature does Chinese jasmine need?
Jasminum polyanthum must not freeze. The RHS growing guide says keep it above 13°C and bring it in before nights fall below about 13–15°C. Another RHS page allows a cool conservatory at about 5–7°C. Keep both figures. It is not the Stephanotis hoop in this set.
