Size and light are the two limits for a small apartment. The sources give sizes for several plants: the RHS lists compact English lavenders at 0.1 to 0.5 m, Illinois Extension: Scented Geranium describes scented geraniums from two to three feet tall to nearly cascading, and UF/IFAS gives paperwhite stems of 12 to 18 inches. Stephanotis and osmanthus are far larger in the RHS records, 4 to 8 m and 2.5 to 4 m.
Sizes from the sources
| Plant | Size the source gives | Source |
|---|---|---|
| Compact English lavender (Hidcote, Miss Muffet, Nana Alba) | 0.1 to 0.5 m tall | RHS lavender |
| Scented geranium | Two to three feet tall to nearly cascading | Illinois Extension |
| Paperwhite narcissus | Flower stems 12 to 18 inches | UF/IFAS |
| Stephanotis | 4 to 8 m tall, 1 to 1.5 m wide; needs support | RHS |
| Osmanthus | 2.5 to 4 m tall, 1.5 to 2.5 m wide | RHS |
Light matters more than size
Every plant above still wants strong light: lavender full sun, scented geranium a full sun location, paperwhites a sunny, cool spot, stephanotis full light. If a flat has limited light, see Lavender Light Indoors and How Much Light Do Plants Need to Flower?.
Smaller options in the guides
Best Lavender for Pots, Scented Geranium Indoors and Paperwhites Indoors cover the compact choices. The larger plants are covered in Stephanotis Indoor Care and Osmanthus Fragrans Indoors.
What the sources do not cover
The RHS sizes for stephanotis and osmanthus are potential sizes, and the pages give no pot-grown size, so a pot-grown plant may stay smaller. They also do not describe apartment conditions such as low light or shared heating.
