Signs of Spring

Just as before, it seems that our ecoroofs seem to know when the season is about to change before anything else does. Over the last week or so, camas has been popping up all over the place on both of our roofs that have some. This year, we also have a new early spring indicator, violets:

If anyone is able to identify this for us, we’re curious to know exactly what it is… But some time last spring a small patch of violets started growing on the ecoroof just outside our bedroom. We really didn’t expect it to last the summer, but its still here, doing quite well, and we would be happy to see it spread a little.

New Plants

This weekend we picked up a handfull of new plants from the One Green World Plant Mobile: yuzu, cranberries, and saffron crocuses. Even though most citrus has difficulties with the Pacific Northwest, yuzu is one of the few that can grow outside all year. I’ve read hardiness claims from 15°F to 0°F. Either way, we’re pretty safe and we’re hopeful for a harvest at the end of the year.

  1. Your violet is most likely Viola odorata (sweet violet), an introduced perennial, native to Eurasia, that is now broadly distributed across North America. A similar native species is Viola adunca(Western Dog violet), which might make a nice addition to your assemblage.

    Isn’t it nice to have a sister-in-law botanist in your pocket? I can confirm when I see you next week!
