Winter joys II

*Hepatica x media ‘Silberprinzessin’ in the feature image.

Modest snow and by the weekend back to spring-like temperatures! It seems we’ll admire for quite a while our “winter joys” in S. Ontario this year.

I will start the second part of this series with Phlomis russeliana, another underused species, in my opinion. The Jerusalem sage, a native of the Middle Eastern regions, is perfectly cold hardy and will grow well in well drained locations, sun to part-shade to form a nice groundcover of large, light green/fuzzy underneath leaves with a felt-like texture. Tall flowering stems with whorls of yellow flowers form in the summer. It spreads slowly by very tight rhizomes, so don’t be afraid, it won’t take over the garden. It grows part-shaded by a large spruce, which also ensures a good drainage.

To its left,  Helleborus foetidus (Bear’s foot or stinking Hellebore), another ‘winter joy’, like all the Helleborus. The more you have, the better. One would think they are widespread in all the gardens here but actually that is not the case. Maybe too expensive? But they are so easy to grow from seeds and you will end up with seedlings to share with all the friends. You can expect the first flowers in the third or fourth year and there is usually a great variation, ie. nice surprises!

The next best thing to the Helleborus spp. are the evergreen Epimediums (few species and hybrids). A subject dear to me, they can be expensive  but worthwhile; long lived and with beautiful foliage all year long. Just like for Helleborus, new foliage will grow up in the spring (also the best time to cut back the old stems/foliage to enjoy the flowers).

I am starting to like more and more the biennial and/or monocarpic species. Many of them develop ornamental leaves rosettes in the first year and remain as such over the winter: Digitalis purpurea, D. ferruginea, some Erysimum species, Ipomopsis rubra, various Cirsiums, Symphyandra, to mention just  a few. You get to know and enjoy the flowers in the second year and then, a choice: grow them again/let reseed or move on to something else :) After all, there is only that much space available and so many other species to grow! I am looking fdw to D. ferruginea ssp. schischkinii to flower next near and will always welcome Ipomopsis rubra and Erysimum witmannii ssp. transsilvanicum.

Last summer the beautiful & monocarpic Cirsium macounii var. edule also flowered and it was source of delight for all, including the pollinators, especially the sweat bees.
Being realistic I admit that I do not have the space to make it a permanent garden resident. It was fun to grow it though and I can share seeds with others more fortunate in garden space.

Other great biennial or short-lived perennials that overwinter as rosettes are: Capnoides sempervirens, Corydalis ophiocarpa, Pseudofumaria alba and P. lutea (Pseudofumaria ssp. remain perennials in this zone).  I already talked about Corydalis and aliases a few times, so will end of the post here.

There are many other plants that remain beautiful over the winter in a cold climate: various ferns and grasses (mostly Carex, Luzula), Mitella diphylla, Tiarella, Tellima, Pachyphragma, Geum triflorum….and probably more could be added to the list.
