Another beautiful garden I had the pleasure of seeing was that of Sir Heaton Rhodes at Tai Tapu...
In this garden were the best plants of Mabel Morse I have ever seen. Unfortunately, the blooms were over, but one could easily see that they had carried a fine lot. This Rose is probably the best of all the yellows when it can be got to grow.

Unfortunately, Mabel Morse and Golden Emblem simply will not grow in Auckland, but both are excellent in parts of the South Island. The climbers of these latter varieties are more satisfactory up north.
