Since we’ve installed several new bog gardens at JLBG this year, we’ve been experimenting with a number of new bog plants. One wonderful surprise has been Parnassia wightiana, an Asian relative of our native species, P. asarifolia, caroliniana, and grandifolia. The fimbriate flowers have been a real treat to watch. These aren’t the easiest plants to grow, and we were 0 for 9 with the 9 species we’ve tried, prior to building much better bogs, thanks to Patrick’s instructions. We’re now on the lookout for other species that might also thrive in these conditions.
And are Patrick’s instructions something you can share?
There are two keys. Planting mix is 50% sand/50% peat, and most importantly is that no runnoff can be allowed to enter.
Love the intricacy of the pretty little white flower!
