March 2023 in the Northern Hemisphere

[MarcR]

My Nemophila; my Corydalis flexuosa and cava; my Eranmthis; my Leucojum; my Cornus mas; my Pulsatilla; and one of my roses started blooming today. My Fritelaria imperialis aeveral Erythroniums and several Anemonies and Cercis Occidentalis are in bud. My Aqiilegias anmd Lupins are showing foliage. It seems like everything everywhere all at once.

Hybrids between Corydalis solida and malkensis occur spontaneously in gardens where both are growing, I never bred them intentionally. In most cases they may be recognized by the broad lip and blush colouring. Where the solida parent was white, it´s more difficult to tell them apart. The pic shows a white corydalis with somewhat broader lip, as well as bracts that show just very slight incisions. I guess, that´s a hybrid as well. The plant in the back and left is definitely C. malkensis, showing the typically more creamy white colour of that species.

Thank you, Mariette. I had thought that C.malkensis doesn't hybridize (easily) with others, but I have also two seedlings which I was wondering if they could be hybrids with C.malkensis and C.solida? The first one has entire bracts like C.malkensis. The other one is very similar but has bracts more like C.solida. Both these flowered for the first time last spring. What do you think?

Luc, your E.hendersonii is so beautiful!

Robert, I also like your E.oregonum. I have managed to grow it from seeds to flower (no clumps yet), and it seems to grow also here, or at least it got through winter 2022 which was very bad. Now they are still under snow.
One more winter picture from yesterday when I saw badger tracks. Poor thing has woken already, I don't know what it will find to eat.

Leena,

The Erythronium oregonum in our garden have been very slow to start stooling out and forming clumps, but they are slowly spreading now.

Have you tried the North American high elevation species of Erythronium? Given your climatic conditions it seems that they would thrive in your garden. These species are extremely beautiful.

My plants are almost all grown from seed ex seeds, so they are mostly E.revolutum (hybrids) and E.oregonum (hybrids). it would be interesting to try different species. I have one year old seedlings of E.grandiflorum, but they haven't been outside for the winter yet. 'White Beauty', 'Pagoda' and 'Joanna' do well in woodland bed.
