This one is so simple to grow - just give it any non-chalky soil, any exposure, and water in times of drought. It spreads slowly, not unlike clumping bamboo, and is very easy to propagate; just dig out reasonably strong canes and plant them wherever you want them, provide regular watering, and wait for the flowers.
It is ubiquitous in Bulgaria.

I inherited this plant with my home purchase 4 years ago. It is in a spot that receives morning sun and afternoon shade. It does take cutting back to keep it healthy and happy. Mine gets a big flush of bright blooms in spring and sporatic blooms through until fall. I deadhead mine so maybe that's part of it's reblooming process. I have recently taken cuttings and I'm not sure yet if they are going to be sucessful. I highly recommend this plant for it's heat and humidity tolerance.

It did not like full morning sun. Always got burnt. So I am trying it in a more shady place. Spring 2008

We've had a plant growing in our yard since I was a child. In the winter when the snow was thick on the ground, the stems of the plant would bend under the weight of the snow and form a cave. We loved to play in our nature-made fort. the blossoms are gorgeous and it's like a golden shower when the winds pick up blossoms as they drop.

One note of caution: The leaves contain small amounts of Hydrogen cyanide, so some caution should be taken with small children and pets.

This plant can really take over once established. It spreads quickly by underground roots much like peppermint. I dig up the wayward "daughters" several times a year and give them to neighbors and friends. It's hard to find in this area at nurseries but well worth having. The bright green stems stand out well when placed adjacent to red trigged dog wood for winter color.

I acquired this plant at a Master Gardener plant swap in a suburb of Atlanta, Georgia. I planted it in a tough spot, up on a hill, shade in the morning, sun in the afternoon, and it is flourishing and quite a sight after being in the ground for three years--this is in my son's yard.

The plant was about five feet tall and had quite established roots, so it was already of some age. I first planted it in a pot with good potting soil, and waited until early Fall to put it in the ground so it wouldn't be stressed by the Summer heat. It is now quite large in the ground, and it's arching branches fill a difficult space up above a parking area on a steep slope.

As just about everything is grey or brown in the winter up at an altitude of about a thousand feet in the Piedmont area near Atlanta--the winters can be harsh--this guy fits right in--with its bare, brown branches in winter--and it comes back reliably every year, bigger and more floriferous than ever. A most satisfactory plant.

I received my start from my sister who lived in Nashville, Tennessee at that time. Once planted, it started growing and blooming for me and has never slackened its pace. Blooming profusely right now in Pensacola, Florida, on August 10th, 2003 in a mostly shaded area. Old things are always worth keeping, plants anyway!.

My mother-in-law gave me this plant several years ago and I have moved it three times. It is in a corner of my shade garden. It gets about 3 ft high in late summer. It has one double yellow/gold flower. Its not my favorate but what could I do but take the gift and plant it? My hubby thinks its just wonderful.

Positive asturnut On May 17, 2003, asturnut from Maurice River Township, NJ (Zone 7a) wrote:

Very low maintaince. Grows in my shady, alkaline, horrible clay soil. Gets no watering or attention. Still flowers so in my book it's a winner. I just don't like that it's diciduous- it looks terrible in winter.

William Kerr introduced the single form in 1804. Its double had been known in Europe since 1700. Has been growing in my yard for many years in filtered sun. I say filtered because it is on the outskirts of a large pecan tree.
