Average Landscape Size: 5–7 ft. tall × 5–6 ft. wide; upright and spreading habit.
Sun Requirements: Full sun to partial shade; in Houston, it thrives with plenty of light but appreciates afternoon shade to keep its massive leaves from wilting in July.
Water Needs: High; this variety is a water-lover and thrives in boggy soils or near water features. Never let the soil dry out completely.
Deer Resistance: Medium
Cold Hardiness: USDA Zones 7–11; in the Houston area, it will go dormant after a freeze but reliably returns from the large tuber in late spring.
Fertilization & Pruning: This is a very heavy feeder. Apply a high-nitrogen fertilizer every 2–3 weeks during the growing season to reach maximum size. Remove tattered or yellowing lower leaves to maintain its clean, tropical look.
Detailed Description: 'Jack's Giant' is the king of the Colocasia family for a reason. It is significantly larger than the common Elephant Ear and grows at a staggering pace when provided with enough water and food. The leaves are a rich, vibrant green with a slight matte finish, held high on thick, sturdy stems. For Houston gardeners, this is the ultimate "privacy screen" or focal point for a tropical-themed backyard. It creates deep, cool shade underneath its leaves, making it a perfect companion for smaller shade-loving plants. Whether planted in the ground or a massive container, 'Jack's Giant' is guaranteed to be the biggest plant in the neighborhood.
