The photo above shows guttation on native strawberry. It's a funny-sounding word, but an interesting phenomenon. The drops on the leaf margins are not dew, but the result of a process called guttation. Guttation occurs at night, when plants accumulate excess water through their roots, but transpiration through stomata on leaf surfaces has stopped. The excess water is released through pores on the leaf margins. Plant is native wild strawberry, or Virginia strawberry, Fragaria virginiana, and photographed on 25 March 2012 in our Biodiversity Garden. Native wild strawberry is an incredibly fast-growing and spreading, sun-loving ground cover with pretty white and yellow flowers and delicious edible fruits. Plant it this season instead of non-native ground covers, such as the invasive periwinkle, Vinca minor.

The strawberry patch in our Biodiversity Garden is the subject of a mini photo-documentary. Every few weeks I'll photograph the same patch and post it here, in order to track the changes it undergoes throughout the year. Plant is native wild strawberry, Fragaria virginiana.
