To turn Hydrangea macrophylla blue use a fertilizer low in phosphorus and high in potassi- um, or the organic approach, Espoma Holly~Tone as directed or 1 tablespoon aluminum sul- phate per gallon of water before buds set in July and then again in August. The more acidic your soil, the more likely your hydrangeas will be blue (pH of 5.5 or below). -

A Gap Analysis of the Morris Arboretum Hydrangea Collection: Sections Asperae and Chinensis This report is available at ScholarlyCommons: https://repository.upenn.edu/morrisarboretum_internreports/68 Title: A Gap Analysis of the Morris Arboretum Hydrangea Collection: Sections Asperae and Chinensis Author: Emily Conn The Martha J. Wallace Endowed Plant Propagation Intern Date: January 2020 Abstract: In this gap analysis of the Morris Arboretum’s Hydrangea collection, I will assess the hydrangea collection with a focus on the “fuzzy leaf” varieties that fall under two classifications: Section Asperae and Section Chinenses. Within these fuzzy leaf groupings, this project will include an analysis of the collection at the species and cultivar level and will outline which hydrangeas are missing from or underrepresented in our collection, as well as recommendations for suitable additions. These recommendations favor wild collected species and species available from the collections at regional arboreta. Discussion of the controversy over nomenclature verification methods, phylogenic treatments, and theories of biological classification systems are explored in the body of this paper. This project also entails seed propagation of target species growing at the Arboretum, and cutting propagation of desired species from local institutions to diversify this growing collection. -

Box 50017, SE-104 05 Stockholm, Sweden Received 25 September 2001; received in revised form 4 February 2002 Abstract Asterids comprise 1/4–1/3 of all flowering plants and are classified in 10 orders and >100 families. The phylogeny of asterids is here explored with jackknife parsimony analysis of chloroplast DNA from 132 genera representing 103 families and all higher groups of asterids. Six different markers were used, three of the markers represent protein coding genes, rbcL, ndhF, and matK, and three other represent non-coding DNA; a region including trnL exons and the intron and intergenic spacers between trnT (UGU) to trnF (GAA); another region including trnV exons and intron, trnM and intergenic spacers between trnV (UAC) and atpE, and the rps16 intron. -

Hydrangeas More Than You Ever Wanted to Know (MTYEWTK)
Hydrangeas More Than You Ever Wanted to Know (MTYEWTK) When I first got interested in hydrangeas, I have to admit I considered the ones I had seen to be kind of “grandma plants” not worth a place in my garden. Then one day at the Washington Park Arboretum I ran into a magnificent hydrangea aspera in peak flower and a new “kick” was born. Maybe it was the hydrangea and maybe it was the fact that I am now a grandpa, but I fell in love. Since then, Bethany and I have scoured wholesale nurseries and botanical gardens to find beautiful hydrangeas for Lael’s Moon Garden and some of our favorites are described below. Hydrangea aspera ‘Macrophylla’ has stunning lace cap flowers of soft purple with stark white sterile florets surrounding them. The plant has large, dark green fuzzy leaves and the flowers extend above the leaves giving it a distinctive look. (A friend called it the Hydrangea from Mars.) This is a large shrub growing to eight feet tall and wide. Afternoon shade is a must; it will sunburn in hot sun. Prune hard when young to develop good branching; thereafter prune lightly to remove dead, crossing or poorly formed branches in late winter or early spring. Hydrangea macrophylla ‘Oregon Pride’ is a stunner. It has dark burgundy stems and strong pink mop head flowers. But there’s more! In our slightly acid soil it has a variety of flower colors all on one plant. Some flowers are the expected strong pink, some are a vibrant purple and some are shades in between. -

A Plantsman's Observations on the Genus Hydrangea
Davidsonia 14:2 31 A Plantsman’s Observations on the Genus Hydrangea The hydrangea family, Hydrangeaceae, is a respectable conglomeration of shrubs, vines and herbaceous perennials resulting from a recent extraction from a behemoth institution known as the Saxifragaceae. The herbaceous components, in the respective genera of Cardiandra and Deinanthe proffer ornamental species for cultivation although it is the woody taxa of shrubs and lianas of this family, in the genera Hydrangea, Deutzia, Philadelphus, Platycrater and Schizophragma, that are by far the most familiar. Other than the exceptions of Hydrangea paniculata and H. quercifolia, the prototypical hydrangea inflorescence is a corymb; a rounded disc of numerous small, fertile flowers that possess insignificant sepals and four or five small often white, pink or blue petals. This cluster of ‘utility’ is surrounded by the advertising agency of sterile florets, or ray flowers, that provide the stuff of ornament. The ovaries are, as a rule, inferior (i.e., enclosed in the receptacle), while the dehiscent capsules, sometimes in the shape of a Grecian water jar, gave rise to the genus name; hydro, water and angeion, a vessel. The foliage is, without exception, arranged in pairs. This floral strategy of sacrificing the fertility of a few flowers to provoke a bit of curiosity by commuting pollinators has co-evolved in other non- related groups, most notably in the genus Viburnum. Thus, it would not come as a complete surprise to those who have grown a double-file viburnum, Viburnum plicatum, that the second Asiatic hydrangea to be noted by Western botanists (in Japan, in 1777) was named Viburnum serratum. -
