Another California strawberry that has interest is the wood strawberry, Fragaria Californica, a plant that usually has small leaves, rather upright in growth, and producing fruit abundantly, though the fruit itself is insipid and hardly worth gathering.

This plant also varies widely in different localities. In the Yosemite Valley I found a most astonishing variation in these as well as in other strawberries. Some of the wild varieties growing there were fully equal to the cultivated strawberry, while others were insignificant to the last degree.

Some of the plants grew strictly upright; others had leaves that hugged the ground and spread in all directions. There was a wide range of variation as to form, size, foliage and fruit. This was quite the most interesting group of strawberries that I have come across anywhere. But these plants do not seem to thrive in the valleys as they do in their mountain home.

As to the latter point, I have noticed a striking propensity on the part of certain strawberries to degenerate when placed under changed conditions of soil and climate.

We have seen that plums and many other plants are stimulated to exceptional growth by precisely such a change. But when the promising wildlings from the Yosemite were transplanted to my gardens they ran to vines and produced very little fruit, although in their native habitat they had borne abundantly.

The experience was precisely the same with certain strawberries that were sent from Alaska, and from Norway, and in many of those from Chili. When the Alaskan vines came to me, they were fruited and they revealed an abundance of splendid berries. But under cultivation in my gardens they failed to thrive and such fruit as they produced was of inferior quality. The new soil and climate, which had proved such a stimulus to Japanese plums and New Zealand rhubarb and European daisies, and almost countless others, proved a handicap to the Alaskan strawberries. The new environment was not adapted to their constitution.

I have sometimes had the same experience with other plants, including certain varieties of currants, blueberries, huckleberries, and raspberries, as well as maples, beeches, hickories, and other trees from the eastern United States.
