Gardeners' Notes:

A friend gave me 3 plume poppy plants last year. I was very impressed by their lovely leavesand the speed and height of their growth, even though where I planted them is shaded most of the time. They multiplied (via runners) soon enough that I was able to plant some offspring in another bed, on the other side of my house. Again, I was impressed by how they managed to thrive, even though they were right next to the house, so got little moisture.


This year I discovered those plants growing all over both garden plots. Like the dreaded chameleon plant, it has fleshy runners that break easily, so I was never sure if I was getting the entire runner out of the ground. Every day new plants appearand they're coming up in the middle of other plants, so they're... read more

Flowered the first year from seed, at about 2 feet. I planted them in very deep shade so it did not grow very tall, and got a bit floppy, but they have very unique leaves. I am moving them when it cools off a bit this fall to a brighter location, and leaving one as a backup in it current location in case the transplant does not work. But from the way it sounds I am pretty sure the transplant wont be a problem. I cant comment on the aggressiveness yet as its too small, but I will be cutting off the flowers after they finish blooming each year just in case. I did not get high germination, 4 out of about 50 seeds, but I dont see any reason to save anymore as everyone's description says they multiply like crazy. The flat seed pods seem to remain on the stems while they all ripen, so should giv... read more

This is a wonderful architectural plant but seems to only survive in Alaska when planted against the foundation of a building where it gets some protection from wind and drying out too much. It does spread quickly along the foundation, but is easy enough to dig out every year to manage the size of the patch. Where happy it gets six to ten feet tall and wide here, so it needs some space and staking.

A very beautiful plant, grown mainly for its bold and beautiful foliage, blue-green on top and silver below. I've seen this grow to 7-8' tall. The pale apricot colored flowers are attractive but very transient.

BE FOREWARNED: it sends out long underground runners at lightning speed. I have friends who're willing to dig them out as the price to be paid for the glorious foliage. (At least the runners are fairly shallow.) I've decided that this plant isn't worth the effort.

It doesn't like being confined to a big sunken bottomless pot. I don't know how it knows, but it stayed short when I confined it to a 10 gallon pot.

I find self-sown seedlings a hundred feet or more from the parent, not in great numbers but often in places where they may not be ... read more

Attracts HONEYBEES! Since they are on the decline, this is a very important plant.

I planted three small plants in a moderately sunny, well drained bed. I thought two died, but they just had done their work underground, making inroads into the back of the bed, eventually popping up in six spots. One year old now they are healthy and about three feet tall. I like their erect, free-standing manner at the back of the bed. They look nice with spirea, salvia, astilbe, daisies, penstemmon and bee balm. My border contains dianthus, hakone grass, small hosta, and variegated ajuga. The combination is really complemented by the grayish green of the plume poppy. I can see that the poppies will need to be controlled as they are a bit invasive.

Yes, it can be invasive, but if you're careful, it's controllable.
It grows FAST. My clump came from a single sliced shovelfull of roots and within three years is probably 3' in circumference. I have mine in a small corner of the yard between our driveway and where the neighbors park and give it no special attention. Watered it a few times in the first year to get it established, but that's it. Chose the location partly because the plant is agressive and partly so that the plumes would catch the evening sun. Am very pleased with the effect.

Don't be fooled by the "poppy" name. We picked up three wee plants at a spring sale, and they grew huge and shot out the long tubers and runners and are spreading all over the place! I'm digging them out but a friend has some in a more appropriate spot and they are lovely -- tall and feathery and the birds like them. Exercise caution and enjoy.

Plume Poppy grows well in our area next to a shaded gate
next to a giant Black Walnut tree.

The foliage is simpy adorable, the leaf shapes render
material for many craft projects.

It appears to enjoy frequent watering, but in our gardens,
tolerates drought well. It is adored in our gardens and I
cannot wait until it begins to multiply.

mine grow about 7 feet tall. They get sun for only about 4 hours per day (N.E. exposure). The leaves are spectacular and it forms a great backdrop. everyone comments on the tropical looking gigantic foilage, not realizing its a very easily grown and completely trouble-free plant. Very hardy here in my zone 3 garden. Self seeds with abandon, but seedlings are not difficult to pull out. I cut back the main stems in late spring to create a more compact and full shrub. Flowers are somewhat attractive but insignificant, they are a light tan color. I water this plant deeply, but only every 2 weeks.

The flowers on mine are a washed out pink\peach colour and mine gets taller than 6ft. Needs to be kept in check if you don't want it wandering into your other plants close by.

Although a bit invasive (I took out about 8 new ones this year for each of my 3 locations!) - I like this plant. The flowers are very fragrant and when dried are quite an interesting addition to a dried arrangement.

Heavy alkaline clay soil seems to kill this one.

Seed has very low fertility rates: sow as soon as possible for best results, no cold-stratification required.
