I bring my Cordylines inside as I have ample space and enjoy the red or purple/black foliage as contrast to so many green foliage plants. I have left one outside but it came back the following spring too slowly...it was just 12" and didn't put on that much growth this summer, whereas the ones wintered inside just took off immediately. My favorite, Alternanthera dentata "Purple Knight", will grow to 36 inches here and will do well inside in pot, hold it's color, even have small fuzzy insignificant white blooms under a lamp or on windowsill. It can be pruned back easily to branch more and form smaller stockier plant. I have a couple of other Alternanthera, no label, one has bright red leaves and another butgundy foliage but only grows to 15" or so. Same care applies. I often cut tall stems along with various large Coleus and Ipomoea batata "Marguerite" or "Blackie" to make a big "bouquet" in water. Rinsing and removing dying leaves is necessary for a week or so but easy and once roots start I have a "living bouquet" until spring...just keep topped up with water. In spring I don't try and plant whole plant with roots...I just make new cuttings and discard roots formed in water. The better the light the more vibrant the colors but sun isn't necessary, just a windowsill...at least here in AL. Even a tall lamp with 150 watt bulb will do. This method also works with Cordylines, by the way...I've cut tops off and put in large floor vase stabilized with black Japanese water stones...or in ceramic pot with just plain rocks. There again, I just make top cuttings in spring to root in soil...the roots formed in water don't adjust well to soil in my experience. I find it easier to grow in water than in a large pot and easier to top up wth water with no aggravation from too much water drainage into overflowing saucer or underwatering. (I have about 100 other plants to care for...LOL). Good luck. josh

Hi, I have zebra grass seeds for trade. I would be interested in your musk mallow or lupines. plmk Lisa

Go figure. I had placed planters with flowers etc. by my purple fountain grass. Now I have purple fountain grass growing in my containers. It's a "natural" arrangement. I've heard the seeds are sterile. But I have some growing. It did happen on it's own though.

Purple fountain grass (Pennisetum Rubrum) does not set viable seed. You'll need to buy actively growing plants or produce by division from larger plants.
