Starting Lisanthus And Other Flowers
Here it is early February, and many of us are itching to start some seedlings. Well don’t. Or at least don’t start your tomatoes – they only require 6 to 8 weeks and would be ready to go in the soil by April if you started them now. That’s way too early. But if you really want to get your fingers dirty and are willing to baby along plants for 4 months, there are things you can start.
Lisianthus Cinderella Echo
Many years ago I commented to a professional grower that I loved lisianthus, a flower that is often sold by florists and occasionally sold by nurseries selling starts of annual flowers. In addition to looking gorgeous in an arrangement, it lasts forever in a vase. I’ve had them look good for 3 weeks or more. But she told me they were fussy. Difficult to get started. She told me I wouldn’t be able to start them myself, but should just buy seedlings (from her, presumably). That sounded like a challenge to me, so I decided to start some.
I did a little research and discovered that there are at least three sizes, or heights of lisianthus. I bought a packet of seeds of each. And they come in 3 colors: white, pink and purple/lavender. I learned that germination is slow: it takes 10 – 18 days at a constant temperature of 72 degrees. Like any seedling, they require good light, not just the sun of a south-facing window. I set up a light stand with fluorescent lights and set the thermostat in the bathroom where they were at 72 degrees. These babies were gonna be happy!
My lisianthus germinated in 18 days. Oh boy! I had a hundred or more seedlings! I adjusted the lights so they were just 6-8 inches above their tiny leaves. Every day I checked them, watered a little if need be, made encouraging murmurs. But nothing much happened. Those tiny green leaves just sat there, glaring at me. They refused to grow. One week, nothing. Two weeks, no change. And on and on. After several weeks they were the size of week-old radish leaves.
Eventually they started to grow, and when they went outside in full sun and got into the soil they took off like foxes in front of

hounds. They grew and bloomed in prodigious quantities. When frost came I dug up big clumps of them and brought them into the house as I couldn’t bear to see them succumb to the cold. In the house they finished up their life cycle after Halloween, if memory serves me well.

But most flowers are easier to start than lisianthus. The advantage to starting by seed is simple: a $4 package of seeds will provide dozens, even hundreds of plants. If you want to overwhelm guests at an August event with bushels of blossoms, you can. And many flowers you can start later, right in the ground. Some flowers that are relatively easy to start outdoors by seed include: bachelor buttons, calendula, California poppies, cosmos, marigolds, morning glories, nasturtiums, scarlet runner beans, sunflowers and zinnias.
On the other hand, starting flowers indoors means getting blossoms earlier. Most seed catalogs are primarily interested in selling you the seeds, so they tell you all about a flower’s wonderful characteristics or history – but not necessarily much about germination time, or how many weeks from seed to flower. One exception to that is Johnny’s Select Seeds (www.johnnyseeds.com or 877-564-6697). They sell to commercial growers and home gardeners and really tell you everything you need to know.
If you are looking for truly rare and wonderful seeds to start, you might want to check out a British company, Chiltern Seeds (www.chilternseeds.co.uk) . The late Tasha Tudor introduced me to their catalog years ago when I visited her at her home in southern Vermont. Chiltern Seeds is the exact opposite of Johnny’s Seeds: they provide no growing information at all, not even hardiness zones for perennials. Of course most of the United Kingdom has a mild climate so cold hardiness is not something they focus on.

What I like about the Chiltern catalog is that it has species of perennial flowers that I can’t find in even a most extensive nursery collection. Now it may be that I do not find Dicentra scandens for sale in New Hampshire or Vermont because it is a perennial that will not grow here. It’s a relative of our bleeding hearts but is a yellow (or pink) climber that it comes from the Himalayas – so it just might. My copy of the plant encyclopedia Botanica lists it as hardy to Zone 4 (minus 30) but I went on line and most people selling seed say it is only hardy to Zone 6 (minus 10 degrees). Either way, germination can take months, even a year, so I shall not buy seeds for it.
My Johnny’s Seeds catalog tells me to plant lisianthus 12-13 weeks before lost frost, so I still have time to order seeds. They have a tall one that is supposed to be dark red that looks awfully good. But I’d better get started soon. I know they’re fussy.
