Comment

Very Hardy. Being stoloniferous, the plant tends to spread out. Further details in Azaleas.

"Azalea viscosum is a tough native plant in America with fragrant blooms in summer. This deciduous azalea blooms in summer. The abundant white flowers have a spicy, clove-like fragrance that fills the garden. The flowers attract butterflies and hummingbirds. Plants grow into multi-stemmed shrubs that put on a show in fall with their flame red foliage.

True to its name, swamp azalea enjoys a soggy spot but can not have its roots submerged in water. It will tolerate some drought. Grow in full sun or partial shade in acidic soil. Prune after flowering for best shape.

Its native range is wooded and open swamps, streamsides; Maine to Ohio south to southeastern Texas and Florida." from American Beauties Native Plants.

"Rhododendron viscosum now includes two closely related forms that were perviously considered separate species, R. serrulatum and R. oblongifolium. The fragrant flowers are generally white to pale pink, and bloom after the leaves have fully expanded. Flowers vary in size from 0.75 to 1.5 inches across depending upon the form, but have a long narrow tupe covered with sticky glandular hairs. The species has a wide distribution from Maine to Florda, and westward to Texas.

R. viscosum was the first North American azalea grown in England. Bishop Henry Compton raised the plant in 1680 from seed collected by John Bannister, an English Missionary. The species was an important parent in early hybridzing efforts with deciduous azaleas. It can be distinguished from the other late blooming white, R. arborescens in that the stamens are greenish white rather than red, and the stems are not smooth but contain hairs." from Special Studies Group of the Middle Atlantic Chapter of the American Rhododendron Society. Further details from S and J Perkins and Ladybird Johnson Wildflower Center.

THE 2 EUREKA EFFECT PAGES FOR UNDERSTANDING SOIL AND HOW PLANTS INTERACT WITH IT OUT OF 15,000:-


Explanation of Structure of this Website with User Guidelines Page for those photo galleries with Photos
(of either ones I have taken myself or others which have been loaned only for use on this website from external sources)

 

or

 

when I do not have my own or ones from mail-order nursery photos , then from March 2016, if you want to start from the uppermost design levels through to your choice of cultivated and wildflower plants to change your Plant Selection Process then use the following galleries:-

  • Create and input all plants known by Amateur Gardening inserted into their Sanders' Encyclopaedia from their edition published in 1960 (originally published by them in 1895) into these
    • Stage 1 - Garden Style Index Gallery,
      then
    • Stage 2 - Infill Plants Index Gallery being the only gallery from these 7 with photos (from Wikimedia Commons) ,
      then
    • Stage 3 - All Plants Index Gallery with each plant species in its own Plant Type Page followed by choice from Stage 4a, 4b, 4c and/or 4d REMEMBERING THE CONSTRAINTS ON THE SELECTION FROM THE CHOICES MADE IN STAGES 1 AND 2
    • Stage 4a - 12 Bloom Colours per Month Index Gallery,
    • Stage 4b - 12 Foliage Colours per Month Index Gallery with
    • Stage 4c - Cultivation, Position, Use Index Gallery and
    • Stage 4d - Shape, Form Index Gallery
    • Unfortunately, if you want to have 100's of choices on selection of plants from 1000's of 1200 pixels wide by up to 16,300 pixels in length webpages, which you can jump to from almost any of the pages in these 7 galleries above, you have to put up with those links to those choices being on
      • the left topic menu table,
      • the header of the middle data table and on
      • the page/index menu table on the right of every page of those galleries.

Site design and content copyright ©January 2007. Page structure amended November 2012. Index structure changed and links from thumbnail to another new page changed from adding that new page to changing page to that new page November 2015. Chris Garnons-Williams.

DISCLAIMER: Links to external sites are provided as a courtesy to visitors. Ivydene Horticultural Services are not responsible for the content and/or quality of external web sites linked from this site.  

 

I am requesting since January 2007 the donation of the following colour photographs of plants for display in this section:-

  • Flower - to show the shape and colour of the whole flower.
  • Foliage - to show the shape of the leaf and its colour. If its colour changes in the year, then a picture of each changed colour.
  • Form - to show the natural shape/growth habit of the whole plant. If the plant is deciduous, then one with foliage and one without.
  • Fruit - to show the shape and colour of the whole fruit/nut/seed produced after it has flowered.
  • Flower Bed - to show the overall effect of a group of plants together, preferably with the names of each of the plants displayed.

Each main photograph will be displayed in a 150 x 150 pixels graphic item. Each thumbnail photograph will be displayed in 50 x 50 pixels graphic item. Freeway allocates 72 pixels per inch. The photographs require to be in JPEG Format and send to Chris Garnons-Williams at 1 Eastmoor Farm Cottages, Moor Street, Rainham, Kent, ME8 8QE England.

Please give the Latin name of the plant and your contact details (It would be preferable that it is either your website or email address rather than your phone number). These will then appear with the relevant photograph. If you happen to be a Nursery, then this link could provide a means for people getting that plant; that they require.
