Range map incorrect

The map shows the red bud range ending in southern Pennsylvania but the article states that it extends to southern New England and does well in New York, New Jersey and points south. How do we chagne the range map? Wkharrisjr (talk) 11:52, 11 April 2013 (UTC)[reply]

As the caption to the map says, this map shows the "natural" range of the redbud tree, at least what was considered to be its native range at the time the map was made. Even though redbuds will grow fairly well outside this range if planted (or if they spread accidentally from cultivation), that doesn't mean they are native outside the range shown. They probably grow quite well under the right conditions in Europe, Asia and Africa too. Many plants actually grow better outside their native range because nothing there has evolved to eat them. These can become quite invasive, and provide little support for native habitats (not necessarily that redbud itself has been found to be invasive anywhere). So for ecological reasons, it is important to know the actual native range of plants, not just where they will grow well. -- Nonenmac (talk) 14:42, 28 August 2015 (UTC)[reply]

Error in Description

The article: "The flowers are pollinated by long-tongued bees such as blueberry bees and carpenter bees. Short-tongued bees apparently cannot reach the nectaries." I don't think this is correct. The western or European honey bee (Apis mellifera) does work this plant. In some areas (western Tennessee) it actually produces a surplus honey flow. John Lovell in Honey Plants of North America on page 194, states "The pink-purple flowers appear from March to May, and yield both nectar and pollen." — Preceding unsigned comment added by 50.96.64.54 (talk) 08:03, 22 January 2017 (UTC)[reply]

Confusing statement

The introductory paragraph states "Species thrive as far west as California and as far north as southern Ontario, roughly corresponding to USDA hardiness zone 5b."

This article is about a single species. I don't understand what "Species thrive ..." means. What species? Does this mean "Other Cercis species," or "Individuals of this species"?

The referenced fact sheet describes a cultivar of Cercis canadensis and, without mentioning California or Ontario, includes a "potential planting range" map that shows that this cultivar might be planted in these areas. This estimation of potential does not support either of the possible meanings of "Species thrive...." Woody832 (talk) 14:03, 7 April 2023 (UTC)[reply]
