Indigo in August

Oh my, this particular species (Indigofera Suffruticosa) does NOT like Calgary’s cooler nights! I noticed every time the temperature dips below 15C, it folds its leaves down, almost looking like the old “sensitive plant” mimosa pudica! We haven’t had many “heat waves” this summer either, a phenomenon in Alberta that is called hot when the temp goes to 28-30C (82.4-86F) for 2 days in a row šŸ™‚

OOO, it’s grown a magnificent 3″ since i transplanted the beginning of August. Much sarcastic joy.

But at the rate it’s grown since it was sown in the middle of May, i don’t hold out much hope for a crop beyond a few handfuls. I’ve tried moving it to a pot with richer soil than it had been started in, and have greenhoused it with a plastic bag suspended over a peony cage, with nothing to lose at this point. We’ll see how it does by the end of August. That’s when temps start dropping even more at night, sometimes down to 6C (42.8F). Not knowing either how “mature” a plant needs to be before harvesting also leaves me thinking there will be little indigotin in whatever i do manage to strip off. Deb’s is past the stage of growing, and is now processing hers and using it…..

I doubt i’ll get flowers, and if i do, i doubt even more that they’ll mature enough for me to collect seed for next year. I’ll chance planting next spring the seeds i have leftover from Deb in Texas this year, but since indigo is notorious for needing fresh seed for each year, who knows what the germination rate, if any, will be. I may try a different indigo type next year, as my first grow attempt in 2014, was Polygonum/Persicaria tinctorium which grew to a very leafy 3 foot height before it was destroyed by hail, another Alberta garden fact.

I have also realized that the way our townhouse is situated that it’s unlikely i will ever have a stupendous garden here, even as tiny and easily manageable labour wise as it is. Late May and June’s sunlight was magnificent, but of course as the angle of the earth turns through the seasons, much less full sunlight hits the backyard…… I REALLY miss the daylong full on Southern exposure the Old House had!!!!!!!!!!!!!

    • Had deer at the Old House, but all they ever ate in my garden was the raspberry leaves in the fall. Next year indigo will be tried in a large pot with a polytunnel cap, and the two varieties i now have. (Assuming they germinate the second year, as they’re notorious for only first year seeding….)
