Diamond Crown ISG Hardy Water Lily

Diamond Crown ISG Hardy Water Lily — Speckled Purple Showpiece with Tropical Flair

The Diamond Crown ISG Hardy Water Lily (hardy × tropical cross) delivers tropical-style, speckled purple-to-pink blooms (≈5–7") on a plant that overwinters like a hardy water lily. In warm water and full sun, Diamond Crown throws showy, freckled petals above clean green pads—an instant centerpiece for lined ponds, wide containers, or earth-bottom shelves.

• Steady to heavy bloomer in warm water with regular tablets

• Great value centerpiece for medium and large water gardens

Plant Requirements (quick reference)

• Sun: Full sun, 6+ hours of strong midday light

• Container: 16–20"+ wide, shallow aquatic container (fabric pots preferred)

• Depth (soil surface → water surface): 8–16" (shallow = more flowers)

• Spread: ~4–6 ft with room

• Soil: Heavy loam topsoil only (no bagged mix, peat, “aquatic media,” or gravel)

• Hardiness: USDA Zones 6–11/12; emerges later than standard hardies

Care & Fertilizing (simple schedule)

• Fertilizer tablets: 6–8 tablets on the 1st & 15th each month (May–September)

• Application: Press tablets 3–4" into soil around (not on) the crown

• Warm-water cue: ISGs flower best once water at crown level is ≈70°F (21°C)+

• Maintenance: Trim spent blooms/yellow leaves; divide annually if crowded

Water Lily Planting Tips

• Plant shallow (8–12") to warm the crown and ramp up buds

• Choose wide, shallow containers; more rhizome run = more flowers

• Keep surface water open and unshaded—pads are your “solar panels”

• Avoid splashing/aeration directly over pads; still water shows freckles best

• Start with normal feeding, then increase to ISG rates as growth surges

Do’s & Don’ts

Do

• Plant in full sun and heavy loam for best performance

• Fertilize twice monthly at ISG rates (6–8 tabs)

• Repot immediately on arrival; keep all parts wet while planting

Don’t

• ❌ Don’t use compost/peat mixes, “aquatic media,” or gravel (they float, rot, or smother crowns)

• ❌ Don’t let floating plants shade Diamond Crown—light drives flowering

• ❌ Don’t plant too deep (>16–18") if you want frequent blooms

• ❌ Don’t place in cold spring water—ISGs stall below ~70°F at the crown
