Tag Archive for: Hepatica americana forms

The melting of the snow in some areas brought to light a few Hepatica leaves in the garden. Among a small pile of pots and containers, the first buds of various seedlings and Hepatica japonica are trying to reach for the sun.

Coincidentally, I am working to update the Hepatica pages, especially assigning collection numbers or names to worthy specimens. The page is not entirely redone yet, but I know that almost everyone is thinking about flowers now, so it is nice to review a few of them :)

Collection numbers and/or names must be kept for records and future references. I am of the opinion that, for genera displaying a large variability like Hepatica, not every single plant must be named. But there are a few ‘special’ ones standing out from the crowd.

I present the newly named Hepatica americana for now, before I am done with all updatings:

Hepatica americana offered as fo. diversiloba in 2022 was named ‘Harlequin’. There is no formal name published/accepted for fo. diversiloba, plus there may be others with different flowers. On this single specimen, besides the leaves with extra lobes, the flowers are variously colored: white or pink or white with pink flushes.

Hepatica americana deep purple of last year was named ‘Purplelicious’. The gorgeous Hepatica americana multipetal white, also a 2022 offering, was named ‘Mihail’.

To review a couple of ‘old’ ones:

Hepatica americana ‘Apple Blossoms’ (offered for a couple of years as H. americana white-pink flares).
And the now famous Hepatica americana ‘#1’. Few seedlings flowered last spring resembling well the mother-plant :)

! There is no guarantee that Hepatica seeds will be collected/available this spring (late May-June), because I intend to do more controlled pollinations and make re-arrangements in the Hepatica collection. It all depends very much on the weather.!

The colder than usual spring this year (2019) has had one advantage: both Hepatica acutiloba and Hepatica americana have remained much longer in flower which allowed me to have a better look at various populations from which I collect seeds.
I followed few previously known specimens from buds to full flowering and then to fading; this allowed me to understand more about their colors in particular.

I mentioned before that most populations of Hepatica americana where I collect seeds are not blue, there is a fair amount of purple; in ‘real’ they are in the blue-violet range (from pastel to pure). I also never liked to use the ‘pink’ name because none are really pink. Light/pastel blue flowered plants are present only in mixed populations.

Last year I postpone it but I finally made the chart seen above (using the RGB palette) which will be used from now on when talking about Hepatica americana/ and H. acutiloba flowers colors.

Hepatica americana typical for the population where seeds are collected

One phenomenon of this spring was that some plants I knew perfectly as being white, flowered with tinges of pink.
It seems that the amount of antocyanins in flowers varies with the temperature, increasing with the cold weather; this is known to happen to other species as well.

Also, in some cases there can be quite a dramatic change from bud to full flowering color – see the transition in H. americana offered as deep pink in 2018; ‘deep pink’ for sure didn’t described it well.
The buds just when they open are actually deep violet. First I thought I was looking at a wrong plant, if not for my label! During flowering the color changes gradually.

Enjoy the flowers pictures, and a new finding with larger than usual flowers. What color is it? Use the chart.
