Like you, I use to use the free seed packets off mags, then it proceeded to be buying selected varieties over the years after reading such mags with the plants that are fashionable at the time. I've made loads of mistakes over those years, and still do, as seeds/plants are quite particular in where they are happy to grow and thrive. In the wild, you'll see plants thrive and that's because the conditions are perfect for them, but then later on, unpredictable weather happens and it dies as it got either too hot or cold for them or too little water or too much water. So, you either mollycoddle them to keep them alive, or you leave it to nature's ways (or my way - neglect!)
Atm, what's flowering is the last dreds of Bowles Mauve wallflower (flower practically all-year round if you like this kind of thing - good for pollinators). This month, I'll have:
viburnam Dawn
daphne Jaqueline Postil
Hellebore - though mainly in early Feb. long lasting to end of March
Crocus
Narcissi - some early varieties, maybe
As the year turns, more and more plants/shrubs and trees come through.
I grow mainly for pollinators and scent. My faves are:
Roses; salvias, sweet peas, cherry blossom (I have Prunus beni-chidori - 2nd time bought, so hopefully, it'll last another year and bloom well for me); hellebores; cyclamen (scented); violas (not big, blowsy pansies); stocks... So many to choose from really.
I try to grow perennials from seed, but I struggle with them as they're a bit harder to germinate, plus some need cold stratisfying or heat and/or take a lot longer to come up. I don't have trouble usually growing annuals, though.
Yesterday, I started a grey oyster mushroom kit for indoors and have bought these as presents for family, so we're charting our progress as we go along. (Met the farmer who's lovely and gave me a tour of his small business and an in-depth talk about his work). This'll keep me going for a bit.
