Pulsatilla

After trying to research the descriptions for the various species we list, we have come to the following conclusions: 1. The taxonomy is screwed up beyond belief. 2. There are only two species, the dayglow orange one that has yet to be discovered and the other one listed below. Perhaps that’s a bit harsh, most of the species we offer are quite distinct, the problem has more to do with the nature of botany. Like many European plants, they have a long history in cultivation and have been described in several languages, which tends to confuse the literature. You can call them Anemones if you prefer just make sure and grow a good selection they are indispensable plants in the spring garden.

Beautiful silvery gray vegetable sheep from New Zealand this species forms ground hugging cushions of intensely silver tiny leaves. I find it relatively easy in pots and troughs but kill it quickly every time I plant it out, customers who live nearby report yard wide mats, I wish I could figure out what it wants in the garden. "Been there killed lots and lots of that".

 

Raoulia hookeri var. albo-sericea PRICE 1@ $6.50

At first glance much like australis, on closer inspection the rosettes are slightly larger, and the cushion has a different texture; a nice silvery mat former, easy as long as you don’t dry it to a crunch.

 

Rehmannia elata ................. PRICE 1@ $5.50

Named for the Russian botanist Joseph Rehmann, Rehmannia has been classified both a Scroph and a Gesnariad and the debate is still not settled.

RODGERSIA AESCULIFOLIA PRICE 1@ $12.00

After growing Rodgersias for a number of years, I’ve come to the conclusion that none of the pure species exist in cultivation. Even if the plants look right like these, with Horse Chestnut foliage and so forth they are probably hybrids, which is actually good from a garden standpoint, being more amenable to cultivation with a bit of hybrid vigor and all.

 

RODGERSIA RED HYBRIDS . PRICE 1@ $12.00

Deep red to pink flowers, and foliage that is often red tinged as well, this strain has produced some of the showiest plants we have seen.

 

RODGERSIA HENRICI HYBRIDS PRICE 1@ $12.00

much like pinnata but taller, with dark red seed capsules and a darker general aspect. be sure to allow plenty of space for all Rodgersias, since they grow slowly but eventually reach an impressive size. these are my favorite discounting the fact that Astilboides has been removed from the genus, but it is after all in a class by itself.

 

RODGERSIA PINNATA .......... PRICE 1@ $12.00

The parent of many of the garden hybrids and a fine plant in its own right, a Chinese species usually with pink flowers.

 

RODGERSIA SAMBUCIFOLIA PRICE 1@ $12.00

Roscoea auriculata ......... PRICE 1@ $8.00

A large broad leafed species, rather stout stemmed that is native to Sikkim, Nepal and Tibet; somewhat intermediate between purpurea and humeana, distinguished by eared appendages at the base of the clasping cauline leaves; flowers are very showy purple orchid like affairs with a 3.7cm upper petal and a 4.8cm lip produced in succession in late summer and autumn.

 

Roscoea humeana ............. PRICE 1@ $12.00

These have not yet flowered but we have high hopes they are the real deal, see the plate in the Ags Encyclopedia if you don’t know what they look like.

 

Rosmarinus ‘irene’ ............. PRICE 1@ $6.50

A trailing cascading variety, hardy for John at H&H, a trifle over hyped but outstanding.

 

rosmarinus 'salem' ........... PRICE 1@ $6.50

Also winter hardy, this makes neat upright plants, my favorite Rosemary.

 

Rosmarinus officianalis 'Silver Spire'            PRICE 1@ $6.50

Outstanding variegated rosemary, stiffly upright, it looks fantastic and has great flavor as well, hardiness is likely to be shaky here although I have not tried it outside.

 

Rosularia aizoon ................ PRICE 1@ $6.50

Similar to chrysantha but with smaller rosettes and deeper yellow flowers Jurasek collected this seldom offered Turkish species so it should be right, usually plants offered under this name turn out to be misidentified.

Holubec’s 1997 collections from the limestones of Ala Dag at 1800m A variable species the form we grow has mid sized glaucous gray rosettes, quite distinctive; I consider it the best of the bunch.

Rudbeckia lacinata 'Goldquelle' PRICE 1@ $6.50

Rudbeckia maxima ............... PRICE 1@ $6.50

Dan Crow turned us on to this one, the huge rounded glaucous blue leaves are very un-Rudbeckia-like, reaching 6'; flowers have tall central cone and are of course yellow. A stunning landscape plant if used properly, Dan has the magic touch.

A rare southeastern species that Dick bought us from woodlanders years ago, we finally propagated enough to offer, it is quite distinct and might produce some interesting hybrids.

Ruellia carolinensis ...... PRICE 1@ $6.50

The well-known wild petunia, large long tubed lavender funnels arise from the leaf axils, I’m surprised that no one has produced tetraploid forms of this.

 

ruellia humilis .................... PRICE 1@ $6.50

Acanthacaea, 2" violet blue Petunia like flowers in the upper leaf axils native to the Eastern States but far to seldom seen in gardens.
