Gardeners' Notes:

Positive dellswick On Jul 24, 2014, dellswick from Quogue, NY wrote:

Yes, this plant has been very deer resistant for me. I live down the street from a wildlife preserve, the deer view my backyard as home. Even with those beautifu stems waving in the breeze, they have not touched them. I have them for about 6 years now, very nice mid border.

I have a question about this plant.....can anyone tell me if the deer like it or not? Looking for proven deer proof plantings. Thank you!!!

A very sweet & delicate looking, but apparently tough addition to a new perennial garden in a new area (for me) here in Fairbanks, Alaska. Bought the original plant our Farmer's Market from a woman who has had perennial sales for years. I always wanted a 'rue'; well it has just come up after a second Fairbanks winter, (with lows last winter at -40F) and it's not even June yet.
This plant would appear better if planted en mass, as the flowers are very light when contrasted with any background, natural or building. I am hoping that it will become broader in it's spot.
I have it planted in partial sun which it shares with some columbine and ornamental onions.

Positive coriaceous On Feb 12, 2014, coriaceous from ROSLINDALE, MA wrote:

This is an especially valuable garden perennial, with elegant architecture, beautifully divided foliage (looks a bit like columbine), and clouds of showy lavender flowers for a long season in mid-late summer. Stems are usually self-supporting. This can be a scrim or see-through plant that works in the front of a border as well as in the rear.

Habit is quite narrow-upright to 6' tall. To create a drift, spacing should be around 18" or even less.

Does best here with consistent soil moisture and some protection from the hottest sun.

Individual plants can be short-lived, but where happy they perpetuate themselves in the garden through self-sowing---lightly and not aggressively.

I bought this plant at the end of last summer and it was an ethereal mass of lovely lavender flowers about 2 1/2 ft. tall at a time when not much was blooming. I was shocked in early May to find that it had grown to 6 ft. tall. (mild winter here in NE PA) Now it is at least 10 ft. tall and so gorgeous. This plant is a winner!

Positive ltalent On Nov 10, 2007, ltalent from New York, NY wrote:

Lovely, delicate bloom that lasts. Although meadow rue is gorgeous in a mass planting, a single plant can be used effectively in a patio garden because of its architectural spine. The lower leaves do fall off -- it's not your fault debilu -so it does need some maintenance. Cut to the ground in the fall.

Neutral debi_k On May 24, 2007, debi_k from S of Lake Ontario, NY (Zone 6a) wrote:

I planted this last year, and both last year and this year, some of the new leaf growth will wilt and dry. I checked the soil moisture and it seemed to be ok, it is in medium dappled shade - I'm not sure why I get some wilt, unless it needs a bit more sun. It seems to do ok otherwise - it still produces foilage and flowers.

Ooopps! I posted the wrong plant! My comment's for Thalictrum delavayi. It's over there now.....

Positive PerryPost On Aug 16, 2005, PerryPost from Minneapolis, MN wrote:

Reseeds itself regularly. Best in a full patch with multiple plants because the flower head is so wispy that one plant won't show very well. Extremely strong stems, stays upright all season.

Kayzie, if you can collect seedheads from somebody or find seeds, this plant is pretty reliable for seedlings. Get enough of them started and some are bound to survive past the deer!

Positive Kayzie On Jun 28, 2003, Kayzie wrote:

This is an elegant plant. Sturdy stalk and yet with whispy delicate flowers. Put together with doppled sunlight and you have a meadow aesthetic from heaven. It was in my very first garden and when I moved I was so excited to plant one in my new garden, but alas, the deer loved it too----sheered the foilage of the branches right off and as the plant grew new foilage, the critter came back to eat the next newly grown gourmet meal I was offering in my yard. I am determined to have meadow rue in my life, I'm not just sure how.

the plant will self seed and seeds will 'take' if they are in the right location (some what moist and partial shade). One of my favorite plants.

An elegant plant for the back of the border. Lacy foliage and lavender flowers appear in fluffy clusters in late summer.
