Answer: This plant is not a fast grower in general. However, with an established root system, it is more likely to fill in quickly than a new plant would. I would be surprised if you are able to locate a fully grown specimen for replanting, however that would provide the immediate size you need. On the other hand, it might or might not be of precisely the same variety (or seed strain or cutting source). Since you have a matched set, I would suggest you be patient with the one you have and allow it to recover. To help it grow faster, you could make sure the soil is kept evenly moist and top dress with compost. An early summer application of a granular completre all purpose fertilizer such as 10-10-10 might also help. Follow the instructions on the label and do not overfertilize as this can do more harm than good.
