| Hi Joseph - The SOH photos as commonly used to market SOH show a deep crimson flower soaked to the bottom of the tube with this deep rich crimson color and these depictions corresponds with descriptions from 1939 first used to describe SOH , but the photos as used to market SOH are most often copies of the few old catalog pictorials and rarely any new original photos of recent origin... The old catalog descriptions of SOH may include reference to some variegation present on the leaves... The SOH strain of Ipomoea nil can gain or loose genes responsible for any feature of the blooms of leaves just like any other Ipomoea nil... The SOH strains most often encountered today are usually some shade of pink or a burgundy-pink color with some degree of red on the limb and most often with a white tube or throat ( which look like "Wine & Roses")
contrary to the original form of SOH... The SOH stock should be continually selected for plants having the deepest red coloration including solid red tubes otherwise these traits will become 'lost' features and apparently this is what has happened after some generations of sloppy breeding... The plant that you are displaying in this thread may have digressed from a SOH type of plant or a "Candy Pink" which (in overall form) looks like a pink version of SOH...or your plant may have originated from stock that resembles SOH regarding some basic features... Those are my thoughts regarding the plant you are showing in this thread... TTY,... Ron |
