Ive had the same heliopsis for 12 years. I keep dividing it, scattering it's seeds, etc. it's pretty long lived. Ive had success growing these in almost full shade and on slopes.

@growitbuildit 3 года назад

That's encouraging to hear you've had some live so long. I didn't take a close survey of my patch this year. But I finally have a decent number of volunteers popping up around our backyard prairie. I'm going to have to try growing some on shady slopes. I've got a partial-open wood slope that faces North and has large competition from many invasive plants. This could be a big help in fighting that. Perhaps I will grow some in larger pots next year and see if I can get them to take.

My Heliopsis gets HUGE, 6 to 6.5 feet. NOT a short-lived perennial - I dug this plant up from my friend's garden 20 years ago and it's still going strong in my garden. I do not feed or water it and it is gorgeous! I have to thin it out every few years which will give me more of these beautiful plants to spread around my other flower gardens. Just like Olga mentioned below, I don't get seedlings either but my plants increase tremendously in size. Also, I do not stake this plant. The tall stalks are strong enough to stabilize on their own. Highly recommend this plant.

@growitbuildit 2 года назад

My plants are going on 5 years, still going strong. I have had self-seeding in the area, but since it is a wildflower area I don't mind it.

A short-lived perennial is one that only lives for 2-3 years such as gaillardia or columbine, but it sometimes varies from region to region and also based on soil conditions. Please keep these great videos coming!

@growitbuildit 4 года назад

Thank you for the clarification. So, I guess my plants are about 100 in 'short lived perennial' years - haha. I knew they weren't biennials, and I figured I should be replacing them soon. Perhaps I should germinate a few more then, as I already planted out the 6-pack of seedlings I showed in the video. And thank you for the nice compliment! I'll try to maintain the quality level. It just takes a long time to get the necessary footage for a video like this. Please be patient as I don't want to put out "filler" just to maintain a schedule.

Hi, will weight in on a couple of things. I have been growing Heliopsis for 9 years. I still have my original plant and it looks like it can go on indefinitely. If it sods in too much to where it gets a dead center, then just divide it up in the fall or early spring. I am in zone 6b Central Missouri. I have experienced pretty heavy deer browse and also rabbits just love to eat the plants, they can take a tall plant and cut it off then simply eat the cut off stem like spaghetti. So, I have had to resort to fencing with chicken wire at the bottom to keep out deer and rabbits.

@growitbuildit 3 года назад

Thanks for the input. This is one plant that the deer and rabbits seem to avoid. At least for me they seem to for the most part. I've learned that plants listed as 'deer and rabbit' resistant is only a suggestion. It seems to vary by location to location.

@g1o2r3a4z5d6 2 года назад

That's a great video of one of my favourite perennials. They also don't seem to be short-lived for me so I'm wondering if that's only a myth that has been sticking around. Anyway, they're growing in our garden in zone 10 in a Mediterranean climate and they do great in the toughest red clay soil. They did need a few more years to get established but after that, they have impressed me with their drought tolerance. They could go all the summer with temps above 30 degrees C / 90 degrees F and only sometimes get a little wilted in the sun but they bounce right back the next morning. I only water them because I love them so much and not because they actually needed any supplemental water. So I would say they are even good xeriscape plants. I grow variety scabra which is said to be even more drought tolerant and a little more compact and I just love the cultivars "Bleeding Hearts" and "Burning Hearts". They even come true from seed. They are fantastic perennials.

These are my favorite native plant. If you want a modified short version, Heliopsis Sunstruck has the same blooms and beautiful varigated leaves and only grows 12-18". They also attract all kinds of pollinators. If you allow them to self seed they'll keep propagating. I just break the stem in half and create a birds nest. That supports over wintering insects and allows them to self seed.

That butterfly is a fritillary. These plants are beset by red aphids. Also, “get ahead of the birds?” Cause they can just go to the grocery store for their food, eh? How many seeds do you need to start a plant this vigorously growing and prolifically seeding? A few seeds. Leave the rest for food for wildlife. I don’t think the birds are eating all the seeds. My seedheads remain all trough winter and next spring and I don’t have seedlings popping up either but the clumps do increase. I keep meaning to transplant and miss the window when they’re young cause they grow so fast.

@growitbuildit 15 дней назад

Hi - if you leave the flowers up over winter, then birds will eat the seed. But if you want to cut them back, just wait until the plant goes dormant/dies back. This should happen as nighttime temperatures are getting fairly cold. You can deadhead flowers to encourage more blooms, even now. just cut a stalk back to the next junction of leaves.

What time of year would you cut these back in order to have them bloom at a shorter height?

@growitbuildit 6 месяцев назад

Hi - the seeds need a cold stratification period to break dormancy. I spoke about it around the 4 or 5 minute mark. But once they have been cold stratified, and outside temps are above 70, or overnight temps approach 60, they should start germinating. If you want to plant in the summer, and stratify in the fridge, I would expect germination within a week or so.

But with other plants, the common treatment is usually allowing for airflow, etc. Also a diluted mixture of hydrogen peroxide can treat it, and diluted milk w/ water can help prevent it.

@growitbuildit 4 года назад

Hi - I just looked it up and it is Heliopsis, so the seed treatment would be the same. But what I couldn't find out is whether Sunstruck was a hybrid or cultivar. I'm guessing it's a hybrid based on the leaves. Hybrids are often sterile or revert back to one of the parent plants. So be aware of that. But, it's worth a shot to try to start some from seed. I would do the same treatment as I showed in this video. But maybe wintersow the seeds in January just so you are sure you have plenty of stratification time.

Cool. Perennial sunflower-like flowers are difficult to ID. I have several species. If it wasn't for bloom time n duration,

Do deer tend to ignore these? 🤔

@growitbuildit 2 года назад

When foliage is young, it can get browsed. But by and large they seem to leave these alone pretty well.

@@growitbuildit Thank you! Are yours exposed? We live on a deer path, so I have been selectively experimenting. We have an enclosed flower/veggie garden, but I an working on adding Flora to our remaining 2 acres. Always looking for ideas. I'm going to winter sow these false sunflowers. 🙏

Hi again - mine are very exposed. Sometimes (though not all the time) I spray the back area with liquid fence. I mainly do this on plants deer prefer. But I can tell you that one year I tested my plants by not spraying at all, and every single False Sunflower survived. My yard backs up to a forest that has a decent deer population. We see them daily in the Winter (no foliage). If nothing else, spray the plants with liquid fence. It really works. You have to keep up with it and reapply after rain, but it will truly keep the deer away. See here (aff link) - amzn.to/3kL8p8n

@@growitbuildit Thank you! I will experiment. I don't think we have access to Liquid Fence in Canada, but we have a product by Bobbex that may be equivalent. I'll look into it!

It basically smells like rotten eggs when you apply it, but you won't smell it in 24 hrs.

These are NOT short lived. I've had mine for over a decade and they reproduce invasively.

Hi - I agree! I was quoting reference material, and my plants were 3 years old at the time of filming (I think). But I'm going on year six, and they are all going strong.
