Both and the abandoned garden survived the bleak winter and produced an abundance of flowers the following spring.,

The answer to be able to appropriately fill in the blank on the question: Both ___ and ___,  the abandoned garden survived the bleak winter and produced an abundance of flowers the following spring, would be: Hardy and profuse. As such, the full sentence would be: Both hardy and profuse, the abandoned garden survived the bleak winter and produced an abundance of flowers the following spring.

Explanation:

The reason comes from the sentence itself and the clues that the words after the blanks give us regarding the type of words we would need. Because the sentence is basically underlining the strength and also the abundance that is present in the garden, despite having been left abandoned, and having been put through the harshness of winter, the two words whose meaning would adapt to serve the purpose and message of the sentence would be the two last ones: hardy, since it means strong and resistant, and profuse, which means abundant or plentiful.
