    Calla lilies, including the Zantedeschia 'Gold Medal', prefer being watered thoroughly once the top inch of soil feels dry to the touch; this usually means watering once a week, though this frequency may increase during hot, dry spells. To water properly, pour water slowly at the base of the plant until it's saturated and the excess water drains from the bottom of the pot. Each plant will typically require about one gallon of water every seven to ten days, but always be wary of waterlogging as calla lilies do not like to sit in water.

  • circleLife cycle

    The life cycle of the Zantedeschia 'Gold Medal', commonly known as the Calla Lily 'Gold Medal', begins with seed germination or vegetative propagation through division of rhizomes. The plant then enters a growth phase where it develops long, arrow-shaped leaves and eventually produces a distinct spathe, a flaring trumpet-shaped bract that surrounds the spadix (flower spike). After pollination, which is often facilitated by insects, the plant produces berries containing seeds, completing its reproductive cycle. During its growing season, the Calla Lily 'Gold Medal' requires plenty of water and good sunlight to flourish. As it enters dormancy, typically triggered by cooler temperatures and shorter daylight hours, the plant's foliage dies back, and the rhizome rests underground. With the return of warmer weather and longer days, the cycle begins anew as the rhizome sends up new growth, reinitiating the life process.

    • Propogation time

      Spring-Early Summer

    • Propogation: The Zantedeschia 'Gold Medal', commonly known as a cultivar of Calla Lily, can be propagated through division, which is the most popular method for this ornamental plant. The ideal time for this form of propagation is in the fall, after the foliage has died back, or in the spring before growth begins. To propagate by division, carefully lift the rhizomes from the ground using a garden fork, ensuring that each division has at least one growing point or "eye". These divisions can then be replanted immediately in well-draining soil at a depth of about 4 inches (approximately 10 centimeters). Water the newly planted rhizomes sparingly until new growth appears, signifying that they have successfully established themselves and started to grow.
