Phormium is a superb plant with a colorful, abundant and very ornamental clump.

Type – perennial
Height – 6 ½ feet (2 meters)

Ideal in a pot on a deck or terrace, it’s also wonderful planted in a sunny garden.
Its low hardiness means it will have trouble surviving through cold temperatures (21°F or -6°C). If winter gets any colder, then grow it in a pot and bring it indoors for shelter.
- In a pot, you’ll only need to put soil mix, perhaps with a little sand mixed in.
- In the ground, you’ll get a batch ready with garden soil + fresh soil mix, again possibly with sand.
- In any case, the soil must drain well.
Multiply phormium easily through clump division after the blooming in fall.
Sowing seeds is also feasible, but more difficult to succeed in.
Caring for Phormium
Once the blooming has subsided, remove floral scapes from the phormium, cutting them as short as you can reach.
- Only remove the leaves themselves when they’ve fully dried out.
- Protect the base in winter with a good layer of dried leaf mulch.
- If in a pot, bring it under shelter so it won’t freeze, but not to a room with heating.
- Leaves wither and dry naturally during the life of the plant: remove them when dry.
Mineral mulch truly highlights the colors of this surprising perennial.
In the ground, water abundantly when the weather is hot, especially during the 2 first years.
- In summer, watering in the evening reduces evaporation and contributes to saving water.
Watering for potted phormium must be much more regular than if it’s planted in the ground. If many phormium leaves dry out at once, it’s certainly the sign that it doesn’t get enough water.
