what size pots now Lyn? You will lose them if you plant them out now I think. My own rooted plants vary from a few inches in 9cm pots to bigger in 3 litres and they will all have some protection either by fleece or gh. Those in the garden will stay out and I will know which are hardiest. Black Adder and Sangria have survived 2 years outside already
kathy, Amistad is not hardy everywhere but cuttings will produce large plants in. Following summer. If you get a plant keep it in gh and plant out in spring. Not too late for Amistad cuttings now....easy peasy
Lyn, i find agastache cuttings best taken in late spring and summer...they enjoy the heat. Have a feeling it might be a little late now but worth a try. they do best for me when soaked for half an hour then dipped in hormone rooting powder. I have cuttings of most if not all of my agastaches but some are slow or resistant. I would keep those plants outside for a while longer but protect inside when it gets colder
One purple that is showing her class now is salvia Amistad. Flowering since mid summer but its now that the colour really shines. And the flowers look larger at this time of year too.
You might like salvia uliginosa Fairy....yes pale blue but with white. Subtle, elegant and classy..oops! ..talking about me again
Never really stop mowing here. Prob Dec /Jan though
All fading a little now but had several weeks of colour
Annmarie, is it reasonably sunny? A shady veg plot is not ideal
to add to already suggested how about a clump of rhubarb.....rhubarb in the veg patch is like custard and,,,,,,,er,,rhubarb
......but not invasive like forget me nots.......still shocked Fairy! You don't like blue flowers? I grow scores of blue plants and love em all.
incidentally, does anyone actually grow a true blue perennial penstemon? True Blue, Heavenly Blue, Sour Grapes, glabra and others are all purple blue. I grew a couple ....Eileen Grenfell rings a bell and another I forget....but they were exceedingly weak growers.
Yes Fairy I do. I'm on display in the tropical dome next to a very rare canna.
