Spathiphyllum Diamond ('SP7018')

The story behind Spathiphyllum Diamond

Diamond is the trade name for cultivar ‘SP7018’, bred by Wim A. J. Brouwer in Nootdorp, the Netherlands, from two compact green-leaved Spathiphyllum parents. It was selected in 2014 for dense growth and distinctive marbled variegation.

Together, the compact growth, soft leaves and pale mottling give Diamond its distinctive look. It may also be listed as ‘Brojedia’.

Keeping Spathiphyllum Diamond healthy

• Light: Choose bright indirect light to support both growth and the variegated pattern. Lower light is tolerated, but growth and flowering can slow. Protect the cream and white areas from strong direct sun.
• Water: Water when the surface has started to dry and the pot feels a little lighter, then drain it fully. Use the drying surface and lighter pot as the regular watering cue; severe wilting means the plant has become too dry.
• Humidity: Moderate to high humidity is useful because pale areas show dry-air damage more easily. Keep the plant away from strong, hot airflow from radiators or vents.
• Temperature: Keep it in warm, stable indoor conditions and away from cold draughts, air-conditioning outlets and direct heat.
• Potting mix: Use an airy mix that holds some moisture but still drains promptly. Bark, perlite or another chunky ingredient can improve drainage and leave more air around the roots.
• Feeding: Feed lightly and regularly while new leaves are forming, following the fertiliser label. Excess fertiliser can contribute to browned tips, especially where water is mineral-rich.
• Repotting: Repot when roots have clearly filled the container or water moves through the old mix too quickly. Move up only one pot size at a time.
• Flowering: If the plant is healthy and flowering has paused, improve the indirect light. Leaves with a high proportion of pale tissue have less green tissue, so low light can slow both growth and flowering.
• Grooming: Remove fully yellow or dead leaves and spent flower stalks. Leave healthy white leaf sections in place because they are part of the variegation.

Problems and solutions for Spathiphyllum Diamond

• White areas turn crisp or tan: Pale areas are more easily damaged by direct sun, dry air and repeated drought. Move the plant out of harsh light, water more consistently and improve humidity before trimming only the fully dead tissue.
• The whole plant droops: Test the mix first. Dry roots can make a peace lily collapse quickly, but a wet root ball with limp foliage suggests stressed or damaged roots rather than a need for more water.
• Leaves yellow from the base: An occasional old leaf is normal. If several leaves turn yellow together, especially while the mix stays wet, check the drainage and roots. Use the yellow-leaf guide to compare patterns.
• Roots are dark and soft: Stop treating the plant as simply thirsty. Cut away rotten roots with clean, disinfected tools, discard the removed material and repot into fresh, freely draining mix. Follow the root-rot guide for step-by-step recovery advice.
• New leaves are scarred, silvered or misshapen: Look closely for thrips, mites and mealybugs around unfurling leaves and on the undersides. Isolate confirmed infestations, clean the foliage, then use a treatment labelled for the pest and repeat at the interval stated on the label. If you are not sure which pest is present, send clear photos to Foliage Factory before treating.

Spathiphyllum ‘Diamond’ is toxic to people and pets

• Keep this plant away from children, cats and dogs.
• Its leaves and stems contain insoluble calcium oxalate crystals, which can irritate the mouth, throat, skin and eyes.
• Chewing may cause burning pain, drooling, swelling, vomiting or difficulty swallowing. Contact a veterinarian or medical professional after exposure, especially if swelling or breathing problems occur.

What does the name Spathiphyllum mean?

Spathiphyllum arose from Greek spathē, meaning a blade or spathe, and phyllon, leaf.

Heinrich Wilhelm Schott established the genus Spathiphyllum in 1832 in Meletemata Botanica, page 22.
