How do I go about starting lupine seeds?
Do I have to chill them?
Do I soak them in water, H2O2, bleach water?
Do I nick the seed coat?
I have read many ways to do it, but which way gets the best results?
I have never had any luck with them, but I would really like to try them again. Any help would be great!!!
I started Lupine seeds back on 3/06 with just nicking the seeds and putting them in peat seed starters (I'll never use peat pots again - suck the water right out of the soil) and they are doing well. Germination period was about 6 or 7 days. Once they sprouted I moved them to larger pots.
Next time I will nick the seeds, soak in mixture of 50/50 Peroxide/warm water for 2 hours under a lamp, then put in damp coffee filter inside a ziploc baggie. Then put the ziploc baggie in a dark warm place for 24 - 36 hours and they will germinate much faster. I used this method recently with moonflower seeds and had great success.
I always just soak them in warm water for 24 hours. Works great. In my zone 7a, they really aren't perennial, so I just treat them like biennials. I start them in late summer in peat wafers and transplant them directly to their permanent residence. I hadn't even considered treating them like annuals and starting them in early spring. Does anyone know if you can do this? Would they bloom the same year?
I wake this thread up for some follow up result. How did your Lupines turn out? Did they bloom within a year, or are they bi-ennual?
Several years ago, I had lucks with sowing Lupines, but it was pure lucks, since I sowed them in a pot of cannas. It must have been in the spring when I did so, and it bloomed for the season. I'd like to have some Lupines this year again, or perhaps next. I love all pea-like flowers lest it be Wisteria or lupines or what's not. Thanks.
I planted fresh seed I had put in a plastic container with sharp gravel and shook for 15 minutes in late mid-August, about covered 1/4" and they germinated in the yard under shade in about 3-4 days, like hair on a dog! I moved them to a spot sunny in the AM when they had a couple leaves. About Thanksgiving, I covered with plastic and 6 inches of mulch. I am in zone 4/5. I expect them to bloom mid-to-late June this year. I have tried other methods (not winter sowing) and often got poor germination.
Olivia, thanks for responding. Your methods reveals that perhaps it's a biennial. Please wish me lucks, I purchased some seeds packages from local box stores. I'll try to scarify them a bit, and put them out this spring for an experiment and will see how they do. I've missed seeing those lovely blooms in my garden.
Ok, so I'm thinking about taking half the seeds (or so) that I have and trying the "shaking with gravel" trick, then soaking them in warm water for 24 hours, and then sowing them with a sprinkling of soil (1/4 inch) where they are going to be.
Any thoughts on that? If I only do half, then I still have some if I mess it up! lol
I have grown a lupine(zone5-6) am right on the line on zone. They didn`t bloom for a couple of years and didn`t even see the plant. I thought I lost it entirely. then 2 years ago it came up and had alot of flowers. Well, last year it was so large and full of blooms just gorgeous. I took the seeds and cleaned them off and let them dry. I got hundreds of seeds. I now have them in a 72 cell planter and so far only 4 have come up. One finally has the look of a lupine with the spicky leaves!! so now I hope the rest make it too. they are a deep purple and beautiful . and today I see the mother plant is coming up again strongly -lots of shoots and leaves.
Two years ago I got great germination by soaking 24 hours in H2O2:water 1:10, then the Deno method (damp paper towel in a baggy) in the fridge. They sprouted in 3-4 weeks.
From my understanding they are short lived perennials, they bloom themselves out. Gertrude Jekyll said, 'To prolong the life of plants, each branch should be cut back 2/3 after flowering, as soon as seed pods begin to form.' I just came across this again, I hope I remember to do it this year!
I had two varieties this season. Instructions: freeze seed for 48 hrs, then soak for 24 hrs. A goodly number from both packages germinated. After soaking, I sowed in individual 3" pots as Lupines don't like root disturbance.
As Lupines bloom, one can get a second flush of blooms by removing the initial blooms as soon as the first florets appear to go to seed... at the bottom of the inflorescence. It is also a good idea to remove the bloom stem before the seeds scatter. Lupines are a common roadside wildflower on the island of Newfoundland.
I started lupines in southern Ohio one year. The seedlings grew fine until I transplanted them. Then they went down hill. I gave them the best soil, the best care, and shade and they died in no time. I was so discouraged! I heard that transplanting is usually their downfall.
When I sowed lupine, several years ago, I did not nick them, but I did wintersow them. I had many, if not all germinate. I suppose if I were to sow any now, I would follow Pam and put them in the fridge after either sowing or Deno, since it is too warm now to even consider starting them in the ground.
Karin ~ Was the weather warm or cool when you transplanted them? I think it makes a difference as I found that they can be handled while being careful in cool weather. If it is warm they would have to be put in pots and grown to a good size before setting them out. They do not tolerate drought.
I think it was in May and warm. I remember transplanting them under a Norway spruce in a raised flower bed which was normally fairly dry there. I love the arrangement of their leaves and their physical size. Do you set the flower pots in the soil or the seedlings? I didn't try them again!
