With its deep purple to almost black flowers, Arum palaestinum is a true standout among spring-flowering plants.
Grown primarily for its near-black blooms, this is one of the darkest flowering aroids available. Often referred to as the Black Calla Lily, Solomon’s Lily, or Lords and Ladies Plant, it delivers dramatic impact in the garden regardless of the name. When in flower, it’s impossible to ignore.
Like many Arum species, Arum palaestinum is a hardy, low-maintenance bulb. It lies dormant through summer, then bursts into growth and flowering in spring. It is also frost tolerant, making it suitable for a wide range of climates.
How to Grow Arum palaestinum
- When to Buy/Plant: Dormant tubers from summer through winter.
- Position: Dappled shade preferred; full sun risks leaf scorch in hot climates like Victoria—add light afternoon shade.
- Soil: Humus-rich, well-drained (neutral pH 6-7) that retains moisture in spring but dries fully in summer dormancy.
- Watering: Moderate in active spring growth (moist but not soggy); completely dry in summer to avoid rot. Not drought tolerant when growing.
- Fertilizer: Balanced 10-10-10 every 4-6 weeks during growth; mulch with organic matter.
- Toxicity Warning: All parts contain calcium oxalate crystals causing oral irritation, swelling, and GI upset—keep from kids, pets.
Gardener Tips
Watch for slugs/snails on new shoots (use baits) and fungal rot from overwatering (apply fungicide if needed). Ideal for goth/dark gardens with its bold drama.
If you’re creating a Goth-themed or dark garden, this is a must-have black flowering plant.
Propagation
- Easy to propagate by dividing tubers every 3–4 years
- Can also be grown from seed
Seed Propagation Steps
Collect ripe seeds from orange-red berries in late summer to early fall after spathe fades. Sow fresh seeds in a well-draining seed tray mix (e.g., 50/50 sand-compost or peat-based potting soil, pH 6-7).
- Lightly press seeds into moist soil surface (do not bury deeply); cover tray loosely for humidity.
- Place in cool, shaded spot (15-20°C ideal, bright indirect light); keep evenly moist but not waterlogged—germination takes several weeks to 2-3 months.
- Thin/prick out seedlings to individual pots once 2-3 true leaves form; grow on in dappled shade, watering moderately.
Time to Flowering
Seedlings develop slowly: first-year tubers form without flowers; expect blooms in year 2-4 depending on conditions (faster in warm Melbourne springs with good fertility). Success rates improve with fresh seeds and consistent moisture during cool germination phase.
Potential Problems
- May self-seed in suitable conditions
- Not drought tolerant
- Flowers have a noticeable odor (and not a pleasant one)
A bold, unusual plant for gardeners who appreciate drama, contrast, and something a little different in the spring garden.
