Yes, thank you

four (9B near 9A) why is there a decline in monarchs?

O.E. disease (research it) is a major reason. Other reasons in site www.monarchwatch.org/

I love this off-comment thread that's wandered from Tall Verbena to Monarchs!

summercloud -- NC zone 7b i wonder how it happened....

Regarding V. bonariensis : From the beginning (tiny sprouts) to now (some qualify to be called seedlings), the green is extremely light. They look well in all other respects, incl roots. The green is much darker in photos of seedlings. Informational comments please from you V.b. gardeners.

V. bonariensis is very pretty!

@four, are your seedlings growing outdoors in the garden or in pots under lights?

If outdoors, has your weather been wet?

Outdoors, sunny, periodic sprinkly rains. Potted, rich loose soil, moisture amount ideal.

In the Netherlands V. bonariensis survives the winters. My brother-in-law had one growing in front of a white wall. He tied it up here and there, and in the end he had a very unusual angular 'climber' there. I still regret not taking a picture. It is gone now, but while it lasted it was fabulous.

Regarding the color of my V.b. plants, commented above, I can report that the cause is the growing medium.

For everything that I grow in containers, the medium is my compost. Excellent results, by the way. I had forgotten the light green leaves of the first plants (milkweed) that I grew in compost., forgotten because leaves of other plants have been of normal color.

Soon after I plant these V.b. into the ground, they begin to darken; and they continue to expected color. Thirty of them, few by few over a long time. None ever darkens while in the compost. Other conditions practically identical in both locations.

(Yes, we are left asking ourselves: why some kinds of plants and not other kinds.)

Are there ever blooms when it is not tall? (either before becoming tall, or after cutting before returning to tall)

Mine do a few lower blooms but the plants leans in all directions so it kinda fills out at all heights anyway

Thanks. Are the lower blooms at top of lower plants, or are they blooms on lower parts of tall plants?

From what I remember they ate just blooming on side stalks of the stems that eventually grow tall.

mild z7

they overwinter plus reseed freely in our region

mine a semi-feral,

grow about 4 feet tall

very transparent

few leaves (2 at each node)

as mentioned before they keep growing

produce shortish side branches on which they flower

sometimes I prune them back hard mid season because there are too many or they fell apart

and they just regrow

Bump OP's question about branching.

Very recently I cut all of them down to 3rd or fourth node from ground, in order to force branching.

Then I trimmed the cuttings, which I am rooting in water :

Any reason not to uproot the dried plants? (They flowered.)

Last year was my first summer with verbena bonariensis, I had sown the seed in early February and plants took their sweet time coming into bloom, this year had started them a month earlier and they were budding up two months ago and have been putting on quite the show ever since! They really look best in groups of three or more, wonderful striking, yet airy plants!!

Looking good there Rouge!

I love these plants @FrozeBudd_z3/4.

I now have had them for enough seasons that they come up naturally each spring from seeds dropped in the Fall and do flower by late July and then continuing.

(I know you are in a lower hardiness zone than I but might this not be the case for you also?)

I used to have raised planter boxes on either side of my driveway, that I had stick verbena in. I would watch for it every spring. And when I would cultivate or dig to do any transplant, I always watched for the verbena seedlings that were about 1/4 high, very dark green leaves and plentiful. Same with an annual dark purple verbena, I think.... that came up each year and would be an excellent weaver no matter what was there. Great in vases too. Oh the years that have come and gone...sigh LOL Hmmm I should have seed somewhere in a cupboard...... Anyway my son is pulling in his semi now for grain hauling and needs the extra space at the entrance, and the planter boxes were about shot anyway....more sigh...LOL

I like your combination with the red, Rouge! Christopher Lloyd would have approved.

When I was taking a picture of my own verbena, I heard a high, twittering sound: a little visitor had arrived!

What a great picture @gdinieontarioz5!

I have had VB in the garden for several years now. This year I made a mental note to be aware as to when the first blooms appeared. All the VB plants this season are self sown, seeds dropped in the previous Fall. And I see I got my first flowers on July 15.

I just got back from the Netherlands three weeks ago. Already halfway June they were in full bloom everywhere. The difference when they survive your winter ;). Mine here are just in bud, no flowers yet.

Rouge, my self sown VB are above my waist height and budding up, will be awhile before putting on much of a show, the transplants though are starting to make a presence. My summers are on the short side, in warmer zones, no need to start these early, for me to get the biggest bang, best I do so.

Mine (unaticipated self-seed) completed a cycle : flowered, flowers dried, plants died.

When I grew it in Texas it quickly became too much of a good thing. It spread by seed, it spread by clumps, it seemed to able to sprout out of thin air, anywhere in the garden. It could grow a big tall clump from a tiny crevice in the concrete.

Mine comes back every year, but i don’t know whether it is the same plant or from self seeding. It is an airy plant and goes well with roses, and different perennial flowers

>"big tall clump from a tiny crevice in the concrete" ___ Surely yours came from another planet.

>"...thin air" ___ Now THAT would be a fitting name for mine; they have no substance. Never knew that flowers could float freely.

Mine come back every year from seed…with mildew! I really like them for the pollinatots but I’m over the disease. I’m ripping them out tomorrow

"I’m ripping them out tomorrow"

Probably just as well! Verbena bonariensis is on the WA State Noxious Weeds Monitor listing, indicating that it has shown invasive characteristics in this area and its spread into natural areas is being closely followed.

Verbena bonariensis attracts more Monarch butterflies, year after year, than any plant in my New England garden. I also enjoy growing Verbena hastata, which attracts a few bees here and there.

Several times I have bought a four pack of v.b. for $3.99. Usually it self seeds. This year I didnt see any seedlings, so I paid $10 for two plants!! Anyway, a week or two passed and I know have probably 30 seedlings that I had not noticed before! I have seen a monarch or two in my Massachusetts garden every day lately, but mostly on coneflowers and butterfly bushes.

I've decided to start pulling my VB out as well! I'm tired of it getting mildew, the flowers aren't worth it. It does self-sow but less than the sweetgum tree, and both plants and seedlings are easy to pull out.

The butterflies love the Verbena bonariensis, but yeah, once you have one of that plant, you have thousands. I think they're very easy to pull out and that's what I do. I try not to let it get too crowded, so I just take hold of a handful of plants and tug. Voila! Instant plant thinning. I had an Eastern Tiger Swallowtail and a Giant here today nectaring on the VB. Actually, the very first GST that I got here some years back was on the verbena. I keep it here because of the love the butterflies have for it, and I also have a 3 butterfly bushes here even though they're considered invasive in PA. I go around deadheading mine and keep a routine of it.

>"once you have one of that plant, you have thousands" ___ Let us qualify that, by adding : PROVIDED THAT you are in a favorable region. ( I am not.)

Verbena bonariensis attracts more Monarch butterflies

Thought of your comment @Coneflower4 when I saw this guy this morning on a stalk of our VB:

UPDATE: July 2/2023

As expected I have hundreds of VB seedlings...most only 12 inches tall or less. But each year I have a few that apparently survive the winter as they are way further along than all the others and flower so much earlier than the seedlings. This one or two showed flowers last week...that's really early.

They must be very well protected by something or other, Rouge. I have never noticed any surviving my winter. If I remember, I will cover a few with pine needles this fall. Maybe that will keep them alive. Btw, they were in bloom in the second week of June in the Netherlands...

It would be the underground part that survives. Yes, heavy covering this fall would increase your odds. I would be inclined to keep intact the above-ground stems, bent flat, even though they will die.

I use the pine needles a neighbour gives me to get Ajania pacifica through the winter. I just cover the whole plant, about a foot high, and it has worked for four winters. I will try the Verbena if I have enough needles and if I remember ;-).

Anyone try the Lollipop Verbena Bonariensis from Annie’s Annuals? I like the idea of a bit shorter version since everything seems to get bigger here than what the tags say.

Ajania pacifica through the winter.

You know @gdinieontarioz5 that the AP that you gifted me is my fave Fall flower? Such neat flowers and cool foliage.

They are now in bloom "everywhere" in our garden. (IMO one of the hardest flowers to photograph.)

(For the life of me I cannot get these plants to successfully self seed just beyond our property in a wild and woolly area of a public space. Each fall for several years I have dispersed seeds there and yet I have never have a seen a mature plant.)

Ha, I intentionally PULL the ones out of the more wild area here because I don't want them to get away and become invasive. In central PA (I'm also in 6A) V. bonariensis self-seeds very readily. The butterflies love it though so I continue to let it grow here, pulling all the extras out every year. If I don't, I think it would totally take over and crowd out all of my other garden plants except maybe the coneflowers. I don't have any other garden plants here that seed so vigorously, and I have a lot of different kinds of plants since I've been butterfly gardening since 2005. V. bonariensis is the very first plant that I saw my first Giant Swallowtail nectaring on. It's a great plant to have for them in the garden, but I control its spread and limit it to my garden and ONLY in the section that has been allocated for it.

Rouge, have you tried setting out a small start of VB? All you need is for one to take.
