| Marsh Marigold (Caltha palustris) |
A Marsh Marigold plant is now in full flower in our pond. Seemingly nothing unusual about that at this time of year, but note there is another Marsh Marigold plant in the pond which is only just coming into leaf. There was a time difference in flowering time last year as well, but not as great as this. Are they simply different varieties which flower at different times? The one flowering now has slightly paler leaves. Or could there be any other explanation? The two plants do have different origins - the one flowering now came from a (garden) pond near Ruthin at about 220 metres above sea level, while the other from one in the Midlands at about 70 metres. It is tempting to wonder whether the altitude, which will affect the temperature, might be relevant. It would be interesting to know whether these plants are flowering at the same time as other specimens from the original ponds.
