At maturity, the typical Vegetable Hummingbird (Grandiflora) will reach up to 20 feet high, with a maximum height at 20 years of 20 feet.

The Vegetable Hummingbird (Grandiflora) is easily found in nurseries, garden stores and other plant dealers and distributors. It can be propagated by bare root, container, seed. It has a slow ability to spread through seed production and the seedlings have medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 49°F. has high tolerance to drought and restricted water conditions.
