Beautiful Eichhornia crassipe

This water hyacinth flower, produced by the aquatic plant Eichhornia crassipes, is highly ornamental and eye-catching. The flowers appear in upright spikes rising above the floating leaves, usually bearing 8–15 delicate blooms on a single stalk. Each flower is lavender to violet-blue in color, with six petals, the uppermost petal marked by a distinctive yellow spot surrounded by deep blue or purple, which helps attract pollinators.

Plant description – Eichhornia crassipes

A bunch of Eichhornia flower plants growing in a garden pond or water container creates a lush, vibrant display. The plants float gracefully on the water surface, forming dense clusters of glossy green leaves supported by swollen, spongy stalks.

From the center of each plant rise upright flower spikes, carrying multiple lavender to violet-blue blooms that stand above the foliage.

The flowers are delicate yet striking, each marked with a yellow and deep-blue patch on the upper petal, giving the bunch a colorful, ornamental look.

Care Tips for Flowering in Tubs or Ponds – Eichhornia crassipe

Sunlight (Most Important)

• Keep tubs in full sunlight
• Minimum 5–6 hours of direct sun daily
• Less sun = more leaves, fewer flowers

Water Quality & Depth

• Use clean, standing water
• Ideal water depth: 20–60 cm
• Change part of the water every 10–15 days to avoid foul smell

Spacing & Thinning

• Do not overcrowd
• Leave space between plant bunches.
• Remove excess plants regularly to allow flowering.

Nutrition (Bloom Booster)

• Add liquid organic manure once every 15 days
  (vermiwash, cow dung water, or compost tea)
• You can also place a small mud + compost ball at the bottom of the tub.
• Avoid excess fertilizer—too much nitrogen causes leaf growth only.

Seasonal Care

• Flowers best in warm months.
• Growth and flowering slow down in cold weather.
• Protect from very heavy rain to avoid plant damage.

Pest & Disease Care

• Generally pest-free
• Remove yellow or damaged leaves immediately.
• If the water smells bad, reduce the number of plants and refresh water.

Maintenance

• Cut old flower stalks after blooming.
• Remove decaying plants to keep water clean.
• Use removed plants for composting.

Important Caution

• Grow only in closed tubs or controlled ponds (it is invasive)

Extra Tip for More Flowers

• Slight stress (limited space + strong sun) often triggers flowering.
• Keep plants healthy but not overcrowded.

Primary Growth Medium: Water

• Grows directly on water, with roots hanging freely

• Suitable for ponds, tubs, cement tanks, barrels, and water gardens

• Water should be still or slow-moving

 Ideal Water Conditions

• Clean, non-salty water

• Slightly nutrient-rich water promotes fast growth

• Optimum pH: 6.5–7.5

• Water depth: 20–60 cm (minimum 15 cm)

Optional Nutrient Medium (For Better Growth & Flowering)

Although not planted in soil, nutrients can be provided by:

• A mud + compost placed at the bottom of the tub

• Cow dung water, compost tea, or vermiwash (once every 15 days)

• Natural pond mud is ideal

 Avoid chemical fertilizers – excess nitrogen causes overgrowth and poor flowering.
