Good morning, Bron.
I have had plants in the house my entire life, and bringing plants in for the winter was a natural transition. I just had to work out the details to accommodate daylilies.
The house temperature ranges from night time 62° to daytime 68°. There is central humidifier which is great for my skin, and makes sleeping comfortable for me, and of course, the plants also benefit.
Presently I have over one hundred daylily seedlings under light, and near a sunny window in an extra bedroom. I have noticed that the seedlings germinate and grow better without a heating pad. However, tomato and pepper seeds and seedlings grow better with the heating pad.
Currently I have Mystic Image with a young scape which should bloom early January. Between now and March, hopefully, there will be many more scapes on many other plants.
I have also pollinated a few daylilies blooming in my livingroom. A few have been self pollinated, and I am most anxious to see what this will produce. Of course, it will be a long wait.
I am a sixty-five-year-old breast cancer survivor, and I hope to live another twenty-five years to watch my grandson grow and mature. Along the way, I will also watch my plants produce babies and grandbabies, and .... I have heard many gardeners say that they are too old to grow from seeds, or to grow hostas from tissue culture.
Take a chance and grow them. Inspire a young person to garden with you and see the fruits of your love for nature.
