Complete Plant Information
Overview
Lilium ‘Grand Cru’ is a spectacular addition to any garden, showcasing the vibrant, reliable performance characteristic of Asiatic hybrid lilies. This cultivar is highly valued for its striking, bicolor flowers featuring bright yellow petals sharply contrasted by deep maroon red centers. As an Asiatic lily, it typically blooms early in the summer season, providing dependable color when many other spring bulbs are fading.
Growing to a manageable height of 3 to 4 feet, Lilium ‘Grand Cru’ is noted for its rigid stems, which often negate the need for staking, making it an excellent anchor in perennial borders. Gardeners appreciate its low maintenance requirements and robust nature, which place it among the easiest lilies to cultivate successfully.
The visual impact of these mid-summer flowers ensures that Lilium ‘Grand Cru’ serves as an excellent focal point or is equally stunning when used as a fresh-cut flower arrangement component, bringing its bold color indoors.

How to Grow
Planting Lilium ‘Grand Cru’ bulbs should ideally occur in the fall, although some nurseries ship potted plants in the spring or early summer that can be planted any time before the ground freezes. These Asiatic lilies thrive in average, medium moisture, well-drained soil, preferring rich, organic composition. For optimal health, ensure the soil allows for proper drainage to prevent bulb rot, but maintain good even moisture year-round; do not let the soil dry out completely. Position bulbs 4 to 6 inches deep, spacing them about 12 inches apart, and plant in groups of three for the best visual mass.
When siting your Asiatic lily, remember the ideal condition is full sun for the top foliage while keeping the root zone cool and shaded—mulching heavily around the base helps achieve this crucial microclimate. Water requirements are medium; deep watering is preferred over frequent shallow sprinkles. While maintenance is generally low, feed lightly, focusing on balanced nutrition before bloom time.
After the glorious flowers fade in June, deadhead spent blooms to prevent seed formation. Do not prune the foliage back immediately; wait until the stems and leaves have completely turned yellow naturally, as this allows the bulb to store energy for next year’s display. Taller specimens, especially if grown in too much shade where stems may weaken, might occasionally benefit from support.
Landscape Uses
This showy flower provides immediate summer color and vital contrast within mixed perennial borders. Planting Asiatic lilies like Lilium ‘Grand Cru’ in distinct groups (threes or fives) maximizes their visual impact throughout the season. The strong vertical lines offered by these 3 to 4-foot stems work well when paired with mounding perennials or lower-growing groundcovers at their base to shade the roots and keep the soil cool.
Beyond the border, Lilium ‘Grand Cru’ performs admirably in containers. While container blooms might be slightly smaller, they offer movable bursts of color perfect for patios or decks. These lilies also serve excellently as vertical accents in foundation plantings where the early summer show is critical.
As an excellent fresh cut flower, ensure you grow enough specimens specifically for indoor enjoyment. Their bold yellow and maroon coloration complements blues, purples, and crisp whites in floral arrangements.

Potential Problems
Asiatic hybrid lilies are generally straightforward, but gardeners must remain vigilant against specific pests and diseases. Lily leaf beetles can cause significant defoliation in infested areas, requiring prompt manual removal or targeted treatment. Disease management focuses primarily on preventing bulb rot, which stems from excessive soil moisture or poor drainage—this emphasizes the need for well-drained soil when planting Lilium ‘Grand Cru’. Furthermore, aphids can transmit lily mosaic virus; controlling these vectors promptly is crucial, as there is no cure once a virus infects the plant. Staking may be necessary only if the plant is positioned in deep shade or exposed to high winds, as stems can become leggy.

Companion Planting
Selecting suitable neighbors enhances the resilience and aesthetics of your Asiatic lily planting scheme. Since ‘Grand Cru’ needs root shade, pair it with lower-growing perennials that have shallow root systems or dense foliage. Hostas with medium green or variegated leaves work perfectly to cover the base, keeping the soil moist and cool throughout the hot summer months. Similarly, low-growing Geraniums or Coral Bells (Heuchera) offer textural contrast while respecting the root zone requirements of the bulb.
When planning color combinations, utilize complementary colors to make the yellow and maroon of Lilium ‘Grand Cru’ pop. Blues and deep lavenders thrive alongside lilies, making plants like Salvia nemorosa varieties or Catmint (Nepeta) excellent choices for the foreground. These companions should have similar cultural needs, preferring medium water and generally well-drained conditions.
Seasonal Care Calendar
Spring preparation is crucial for success with this bulbous plant. As soon as the ground thaws, ensure adequate moisture returns to the soil, and apply a layer of organic mulch (compost or shredded bark) around the base of the stems to keep the root zone cool as the plant emerges. Avoid high-nitrogen fertilizers too early, as this encourages weak, floppy top growth susceptible to wind damage and mildew.
During the active summer growth and bloom period in June, maintain consistent moisture without overwatering, especially if rainfall is scarce. If stems become top-heavy from successive blooms, provide gentle support before they break. After flowering, the most important task switches to foliage stewardship: resist the urge to cut back stems immediately; allow leaves to fully yellow, which signals the bulb has successfully recharged its energy reserves.
Winter preparation for Asiatic lily is minimal, reflecting its low maintenance rating. Once stems have fully died back naturally in late fall, you can cut the dead stalks near the ground level. No extensive winter covering is usually required in Zones 4-8 if planting depth (4-6 inches) was correct, as the bulb is well-insulated by the soil itself.
