Clematis otophora and Clematis texensis

Here are a few pictures of the first flower from one of the Clematis otophora plants in my collection (plants were obtained from Far Reaches Farm).  I purchased this plant because I was interested in using it to make hybrids with Clematis texensis.  I have already been able to do this as I currently have both species flowering.  Here are some pictures.  More pictures of C. otophora yet to come.

Here are some photos of C. texensis still flowering in my garden now.  These remarkable and richly colored flowers have been produced sporadically since May.

Gentiana autumnalis

Gentiana autumnalis is flowering in my collection this year, about 10 months or so from seed.  The seed was collected in Ocean Co. NJ by a friend and sent it just after it was collected.  This resulted in a high germination percentage and many seedlings.  2 precocious individuals are flowering and I could not be happier.  I would still like to see this species in the wild and it will be interesting to see if this can be grown as a garden plant.

Sarracenia Roll Call

Many Sarracenia species and hybrids can look their best in the fall.  Some clones of Sarracenia leucophylla produce the best pitchers at this time, and can provide for a stunning show.  Here is a variety of plants in my collection that currently looking quite good.

This is a form of Sarracenia alata that I collected from a roadside in Stone Co. Mississippi.  This is the darkest colored form in my collection

 A clone of Sarracenia luecophylla I collected from a construction site in Escambia Co. Florida.  Slow growing and produces more pitchers in fall than in spring.

A form of Sarracenia leucophylla referred to as "Georgia Giant", but I am not sure if this is a legitimate cultivar name.  None-the-less this is my favorite clone.

This Sarracenia rosea may be the most fascinating and beautiful plant in my collection.  This clone resemble S. rosea f. luteola, but does not completely lack red or pink pigmentation.  The flowers are also a darker color than typical S. rosea.  Perhaps this represents the progeny of repeated backcrossing and introgression among 2 or more species.

Sarracenia rubra ssp. rubra from Taylor Co. Georgia.  This for is a bit larger than typical S. rubra and is has recently been suggested that this may represent a new, previously undescribed taxon.

This is not Lilium catesbaei

Here are some photos of the Lilium catesbaei imposter from the NARGS seed exchange.  I believe this plant to be Lilium formosanum.  Back in June, I was given 3 plants from the accession and now one os flowering and the other is in bud.  Pictures of both are attached here.  Anyone disagree with my identification?

Some fall flowering natives everyone can get excited about

This is the exceedingly rare Balduina atropurpurea, and is known in the vernacular as purple disk honeycombhead.  This denizen of pitcher plant bogs and pine savannas is quite rare in the wild; most populations can be found within the state of Georgia.  Despite being found growing in relatively sterile sand in the wild, in cultivation this plant demands a decidedly nutrient rich medium.  I did small small experiment where I planted seedlings in 50:50 sphagnum/silica sand medium and same in basic pine bark based nursery medium.  All plants have survived, but the plants in the pine bark medium have far and away out performed all others and can be seen flowering in these photos.  Those in the sphagnum/sand medium did not flower this year.  So far I have only grown these plants in containers as I am unsure of their hardiness.  

Another view of Balduina atropurpurea.  The flowers are nearly three inches across.  One of the most unusual and interesting features of this plant are the succulent leaves.

This form of Physostegia virginiana finished flowering a few weeks ago.  I collected this form from the banks of the Olentangy River in Delaware county Ohio.  This was growing in rocky, wet soil and is something quite different when compared to the forms of this species that grow in limestone barrens in southern Ohio (referable to P. virginiana var. praemorsa).  Several variants of this species have been described in the past, but current thinking lumps them all under P. virginiana.  While this may look like the common Obedient Plant that is commonly grown in gardens, a more complicated botanical question lurks in the background.  Questions like this can begin to be answered when wild-collected forms of the species are collected from throughout the range of a given taxon and grown together in the garden,

This super rarity is Silphium glutinosum, an Alabama endemic.  This seed grown plant is flowering in it's first year and I have been quite taken with the 1.75-2.5" diameter, pale yellow flowers that have been produced throughout late summer.  Accordingly, this plant is quite sticky, and in the greenhouse fungus gnats have become stuck on the plant...perhaps we are seeing early stages of carnivory?

Chelone glabra, the white turtlehead is a fantastic fall flowering native species.  This photo was taken of plants in Hocking county Ohio and are referable to C. glabra var. elatior.  In Ohio, C. glabra var. elatior is confined to the eastern portion of Ohio on the west edge of Allegheny Plateau, where the soils are derived from sandstone and generally more acidic.  Tn this habitat, the white turtlehead is associated with a different set of plants than populations from further west in Ohio.

Here is a similar form of Chelone glabra from Campbell county Tennessee

So far, my favorite forms of Chelone glabra are those found in west-central Ohio and are referable to C. glabra var. linifolia.  As the name indicates, the leaves are more linear than var. elatior, but the most obvious feature of the plant is the green apex of the flower, giving a totally different aesthetic.  This variety is a fen indicator species and grows in lime-rich, saturated soils with some of Ohio's greatest rarities such as Cypripedium reginae and Parnassia glauca
