OT: Black Walnuts--More juglone tolerant plants

The Borer happily noted that these irises will tolerate juglone:

<<bearded irises - all types, siberians, japanese,reticulata.... and hosta,
daylilies, aquilega, hollyhocks, primula (all kinds), ferns, pulmonaria,
heuchera, delphiniums.>>

To which the article adds, and I add for all those living with this juglone
issue:

Weeds:

Vericona filiformis.

And The Borer continues: 

<< Plants that I can't grow, so gave up trying:  tomatoes (not a problem....
they
 sell them here), cherry/weeping cherry tree,......I suspect astilbe>>

Astilbe should grow okay if it is getting enough moisture. It's on the
tolerant list. 

Tomatoes are very, very susceptible according to the article, and plants
growing in clean soil in pots were severely stunted when leaves and fruits
fell into the pots. And you can give up on the weeping cherry if it is Prunus
subhirtella "Pendula".  

Also apparently susceptible:

All trumpet and large flowered flat cupped narcissus including "King Alfred",
"John elyn", Unsurpassable", and "Ice Follies", some tulip cultivars including
"Merry Widow" and "West Point" ,Aquilegia coerulea, Aquilegia canadensis,
Lilium "Enchantment" and other Asian hybrids.

Juglone proved fatal to: Aronia arbutifolia, Baptisia australis, Pinus
mugo,Rhododendron "PJM" and "Purple Gem", and Viburnum plicatum "Mariesii. 

Roses were injured by the application of a compost containing black walnut
sawdust.

The author, Frank Robinson, who at the time of the writing of this article was
living near Charlottesville, Virginia but who is now the Director of the Lewis
Ginter Botanical Garden in Richmond, spoke from his experiences on his own
property, which he said was not compulsively gardened. The article resulted in
several letters in reply: in the January 1987 Issue of Horticulture it was
noted by others that the following do fine with black walnuts: Picea abies,
Bumelia lycioides, Crataegus phaenopyrum, Thuga sp., Physostegia sp.,
Kolkwitizia amabilis, Juniperus communis, Syringa vulgaris, Dicentra
spectabilis, and Viburnum lantana. Other questions caused Robinson to respond
that from observation these were apparently fine with Black Walnuts: Cornus
florida, Castanea dentata, Koelreuteria paniculata, Fagus sylviatica, Buxus
sempervirens, Ligustrum vulgare, Wisteria floribunda, Forsythia x intermedia,
....and Iris x germanica.
