Q. I have a black walnut tree, and I would like to plant other things near it. I have heard that black walnuts give off a toxin through their roots that kills everything you plant. Is this true?

A. Yes, walnut trees do release a toxin from their roots, but some plants don't appear to be affected.

Here is a list of these plants assembled by the University of Illinois.

Ajuga reptans (bugleweed)

Alcea rosea (hollyhock)

Asarum ...

Seattle Post-Intelligencer (Seattle, WA) ; Sanguinaria canadensis f. multiplex Double-flowered bloodroot The woodland comes alive in early spring as many bulbs and perennials begin to bloom. This includes the double-flowered bloodroot, Sanguinaria canadensis f. multiplex. This perennial grows from a rhizome, which is an underground
Branch yield components controlling soybean yield stability across plant populations.
Crop Science ; Determination of optimal plant population (the minimum population for best yield) lowers seeding costs, reduces lodging, and ameliorates disease problems (Boquet and Walker, 1980). However, previous plant population studies have shown variable results. Optimum population can be anywhere from 30 000
Inflorescence sampling improves effective population size of grasses.(Plant Genetic Resources)
Crop Science ; THE WESTERN Regional Plant Introduction Station (WRPIS) maintains more than 17 000 forage and turf grass accessions. The majority of these are self-incompatible, wind-pollinated species with high levels of heterogeneity. Initial and periodic seed regeneration is needed to maintain this collection
PLANT OF THE WEEK: SANGUINARIA CANADENSIS.(Features)
Daily Record (Glasgow, Scotland) ; CANADIAN bloodroot, also known as Sanguinaria Canadensis, doesn't sound a particularly attractive plant But this little woodland plant is one of the most entrancing plants for a shady place. It first appears in early spring. Small pinkish-grey shoots push their way up through the ground like
Plant species mediate changes in soil microbial N in response to elevated CO2.
Ecology ; INTRODUCTION Nitrogen (N) strongly limits plant growth in many terrestrial ecosystems (Vitousek and Howarth 1991), potentially constraining the response of terrestrial ecosystems to elevated C[O.sub.2] (Bazzaz and Fajer 1992, Field et al. 1992). Elevated C[O.sub.2] could modify N availability to

Daily Record (Glasgow, Scotland) ; SANGUINARIA CANADENSIS 'PLENA' This lovely plant first appears in early spring, when putty-coloured shoots push through like mushrooms. Within days these unfurl into grey-green leaves, each folded round a flower. The leaves are scalloped and frosted white on the underside, but the flowers are even
Determinants of Plant U12-Dependent Intron Splicing Efficiency
Plant Cell ; Factors affecting splicing of plant U12-dependent introns have been examined by extensive mutational analyses in an in vivo tobacco (Nicotiana tabacum) protoplast system using introns from three different Arabidopsis thaliana genes: CBP20, GSH2, and LD. The results provide evidence that splicing
