There are many species of Hawthorns and confusing species, as Eloise Butler describes at the bottom of the page. The large Garden specimen is on Geranium Lane. Martha Crone wrote in the April 1961 issue of The Fringed Gentian™ "The trees in May offer many lovely sights, but none finer than when in bloom, especially the wild cherries, plum and hawthorns." Read Eloise Butler's notes below.
Hawthorns will grow into small trees up to 25 feet in height. Tree or shrub, they have a round-top form with branches having a few long sharp thorns. Tree shapes may develop several trunks branching from the lower main stem. Stems of 8 inches diameter would be considered very large. Bark is a scaly dark brown. Twigs are mostly hairless.
The leaves are 1-1/2 to 2+ inches long, ovate to round, stalked, with very shallow lobes above the middle and doubly serrate coarse teeth on the margins. The upper surface is a dull to shiny dark green with sunken veins, the underside paler in color with fine hair on the veins and sparse hair on the surface. The lower teeth, at a minimum, are gland-tipped.
The inflorescence is a loose cluster of 8 to 15 stalked flowers appearing with the new leaves and rising from the leaf axil. Flower clusters and leaves appear at the outer edges of the twigs.
The flowers are 5/8 to 7/8 inches wide, 5-parted, white petals, 5 to 10 stamens with yellowish anthers that turn reddish-brown at pollen maturity. There are 3 or 4 styles. Around the base of the stamens are a cluster of yellowish nectar glands. The calyx has 5 sharply pointed lobes, which persist onto the fruit.
The fruit of this species matures to a fleshy red berry (A POME), 3/8 to 1/2 inch in diameter. Prior to maturity, the calyx lobes of the flower are reflexed on the immature fruit. The pulp is somewhat sweet and holds 3 or 4 nutlets.
Habitat: Fireberry Hawthorn and many others will grown in a wide range of soils that are not acidity. Full sun is best for shapely growth but the plant will grow and flower in the understory if it gets partial sunlight during the season and more sunlight in the spring before the over-story gets dense. The root systems goes deep so older specimens should not be transplanted. This is a slow-growing and long-lived plant.
Names: The genus Crataegus is from the Greek name for the tree, derived from kratos, meaning 'strength' and alluding to the strength or hardness of the wood. The species name, chrysocarpa, is derived from the Greek chrysos, meaning 'golden' and carpa meaning 'fruit'. Irregardless of that, the fruit of this species however passes through the golden stage to a deep red which gives this species its current common name of 'Fireberry'. The author name for the plant classification - ‘Ashe’ refers to William Willard Ashe (1872-1932) American forester and botanist, plant collector, member of the Torrey Botanical Club and was employed in numerous positions by the U.S. Forest Service from 1905 until his death.
Comparisons: As Eloise Butler explains below, Hawthorns are very confusing. There are a number of very similar trees and one must look at the type of thorns, the size of the pome, number of flowers and the leaf. The MN DNR lists 13 species that are native to Minnesota with 7 of those found in Hennepin County. Fortunately botanists have consolidated many species, previously described as separate species or varieties. However the list in North America is still hugh. There are 27 previously listed species alone that have been consolidated into C. chrysocarpa. Red Haw is classified as C. chrysocarpa ashe var. chrysocarpa.

Notes: Hawthorn is native to Minnesota in most counties from the central area northward and a few counties in southern Minnesota. Fireberry Hawthorn is widespread in Minnesota, absent mainly in counties around and south of the Minnesota River. In North America is is found in all the lower Canadian Provinces except British Columbia and in the U.S. it is found in the eastern 2/3rds of the states except for the Old South, and in the west it is found in the mountain ranges at lower elevations.
Hawthorns are indigenous to the Garden area. Eloise Butler catalogued six species in her Garden Logs as early as April 29, 1907. One early one was listed as Crataegus rotundifolia, which is now classified as C. chrysocarpa Ashe var. chrysocarpa. In her 1926 article Shrubs in the Wild Garden she listed this as one of the 10 most common shrubs in the Wild Garden. In Martha Crone's 1951 Garden census, she listed three hawthorns as present in the Garden: Big-fruited (Crataegus macrosperma), listed simply as Hawthorn on her list; Downy Hawthorn (C. millis - should be "mollis"), and Dotted Hawthorn (C. punctata) which she mis-identified as "large-fruited" - that is actually the name for C. macrosperma. These three were also part of the six listed in Eloise Butler's logs. Curiously, Martha Crone does not list C. chrysocarpa, which is the identification of the Garden species on the 1986 census, and is also the earliest identified species on Eloise Butler's logs. The most recent census simply lists Crataegus ssp.
Eloise Butler wrote: "Many are the allusions to the hawthorns of England in poetry and prose. Indeed, the very name, England, calls up to the observer of plants a mental picture of hawthorn thickets and hedges. It is pertinent to ask why writers neglect to extol the American species. For our hawthorn trees or shrubs are of extreme beauty, when covered with their snowy fleece of bloom, or when glowing with the sweet tasting, stony bright red “thorn apples.” The leaves of the hawthorn may have margins varying from toothed to lobed or divided. The thorns may be long and stout, or few and feeble; thus belying the name.
Of all the botanical mazes, that of the hawthorn is the most intricate. In Gray’s seventh edition, no less than sixty-five species of the genus are described, as well as many varieties. Some botanists go so far as to affirm that every individual is a different species. When the ordinary student wearies of cudgeling his brain over minute differences of stamen, nutlet or whatnot, he ignominiously names the species “Crataegus sp.?” or passes on the puzzle to the greatest authority, Professor Sargent, the director of the renowned Arnold Arboretum of Boston. Those desirous of extending their acquaintance of hawthorns may see grouped together in this arboretum the largest collection of both native and foreign species known to the world." Published June 4, 1911, Sunday Minneapolis Tribune (read entire article).
Superstition: There is an old English superstition that bringing Hawthorn blossoms into the house would be followed by illness and death. It was asserted in Medieval times that the smell of the blossoms was similar to the smell from the Great Plaque. It would be years later before botanists would discover that the hawthorn blossom contains the chemical trimethylamine (N(CH3)3, which turns out to be one of the chemicals formed in the decay of animal tissue.
