5 FLOWERS THAT ARE DEAD SIMPLE TO GROW FROM SEED
Here are five of my favorite super simple flowers to grow from seed. And when you see how much these plants cost at the nursery you'll wonder why you weren't doing it sooner.
NASTURTIUMS
'Cherry Rose' nasturtium |
Are you sick of me blabbing on about nasturtiums yet? I'm sorry, but I really can't say enough about them. To review: They are beautiful, edible (both leaves and flowers), may help fend off "bad" insects and, most importantly, are easy as pie to grow.
The seeds are quite large, usually bigger than a pea, which makes them easy to handle and easy to plant. They have a hard seed coat, so it's a good idea to soak them first. I used to soak them overnight, but then I switched to a shorter soak of two to three hours in hot water (changing the water a couple times to keep the temp up) at about 85 or 90 degrees. I haven't noticed a bit difference, but I've forgotten seeds before while soaking and that definitely isn't good.
I usually start them with three seeds in a 4-inch pot but I've also grown them in soil blocks. They are equally easy to direct sow in the garden. I'll start several kinds early inside but then I go back later and fill in empty holes in the garden by popping in a few seeds.
Nasturtiums are great for filling in empty spots in the garden. |
POPPIES
Even in a crowded border, poppies will hold their own and look great doing it. |
Equally as beautiful as the flower, or perhaps more so, the seedbeds of poppies continue to shine after the blooms are spent. |
I've grown something very similar to this in the past but this year I'm adding Iceland poppies that I think I'll start indoors just to be safe.
CALENDULA
'Geisha Girl' Calendula |
I start them in soil blocks but small pots or cells would work fine too. Plant them about 1/4 to 1/2-inch deep as they need darkness to germinate. I put them on a seed-starting heat mat at 70 degrees. Every time I've grown them I've had about 99% germination. You can certainly start them outside as well by direct sowing. I start them about eight weeks before my last frost date and they can be planted out a couple weeks before the last frost, although I don't recall ever doing that, only because I like to plant all my annuals at the same time and so many can't be planted out early.
Orange calendulas are so bright even a few random flowers stand out in a garden. (Bonus prize for counting the number of poppy seedlings coming up in this photo.) |
NICOTIANA
Nicotina alata 'Lime Green' |
I love how nicotianas look mixed in a bright annual planting. Because I start them from seed I'm able to plant them in masses for just pennies. |
They need light to germinate, so don't cover them, just gently press them down so they have contact with the soil. I also put them on the heat mat. Then be careful to only water from the bottom or use a mister until they germinate so you don't wash them away. Start them about eight weeks before the last frost, potting them up as necessary. They can be planted outside after the danger of frost has passed.
CASTOR BEANS
What kid hasn't been handed a cup full of dirt and a dried bean and been told to plant it as a grade-schooler? Kids are filled with pride as the bean quickly sprouts and grows to a size large enough to take it home and present it to their parents. Teachers pick beans because they are pretty much guaranteed to grow and the same holds true for castor beans.
I start them in 4-inch pots about six weeks before the last frost, planting them one per pot, about 1¼ inches deep. I give them some bottom heat to get them started on the seed mat. Once they germinate and start growing you have to be careful about giving them even light or rotate them at least once a day as the plants can take off in one direction seeking sunlight and never really straighten out.
The spiny flowers of castor bean are unlike anything else in the garden. |
It's important to note that all parts of castor beans are very poisonous, so some care must be taken in where you plant them. And although I love the spikey, bright red flowers, I don't bring them inside because I don't trust the cat to leave them alone.
I've grown 'Impala' and 'Gibsonii' and wouldn't be able to pick a favorite. 'Impala' is a "dwarf" variety, meaning it stays about 5 feet tall or less but 'Gibsonii' has spectacular flowers and has more of a tendency to flop later in the year, especially if they get dry.
There are many other flowers that grow very easily from seed but I've either never grown them (or not grown them for several years and have therefore forgotten their habits) or for whatever reason I personally haven't found them to be as easy as other people have so I left them off the main list. Still, they are worth checking out:
- Sunflowers
- Zinnias
- Cosmos
- Marigolds
- Violas
